RISK FACTORS

      In addition to the other information contained in this prospectus and in the documents incorporated herein by reference, including our consolidated financial statements and the related notes, you should carefully consider the following factors. If any of the following risks actually occurs, our business could be harmed.

Risks Related to the Offering of the Notes

	We have a significant amount of fixed obligations that could impair our ability to make principal and interest payments on our debt obligations, including the notes, and lease payments on our lease obligations.

      We have, and will continue to have, a significant amount of fixed obligations. Due to our high fixed costs, including aircraft lease obligations and debt service, a decrease in revenues results in a disproportional greater percentage decrease in earnings. As of March 31, 2004, we had approximately $2.0 billion of future lease obligations payable over the next 16 years and we had approximately $605.7 million of indebtedness outstanding (including current maturities), comprised of $253.9 million in notes payable related to 11 of our CRJ-700 and CRJ-900 aircraft, $25.3 million of notes payable on interim financing of regional jets, $97.5 million outstanding under notes payable related to our fleet of Beechcraft 1900D turboprop aircraft, $100.1 million outstanding related to the issuance of the senior convertible notes due 2023, $100.0 million outstanding related to the issuance of these senior convertible notes due 2024, $23.8 million related to two CRJ-200 aircraft, $3.8 million related to the settlement of past contractual claims of an aircraft manufacturer, $1.0 million related to a mortgage note on one of our real estate properties and other miscellaneous debt totaling $0.3 million. In addition, we had $11.6 million in letters of credit outstanding at March 31, 2004 under our credit facility with Fleet Capital Corporation.

      Our outstanding indebtedness and lease obligations could have important consequences to you. For example, it could:

	•	make it more difficult for us to satisfy our obligations with respect to these notes;
	•	limit our ability to obtain additional financing for funding the expansion of our aircraft fleet, capital expenditures, acquisitions, working capital or other purposes;
	•	require us to dedicate a material portion of our operating cash flow to fund interest payments on our indebtedness, thereby reducing funds available for the expansion of our aircraft fleet, capital expenditures, acquisitions, working capital and other purposes; and
	•	reduce our flexibility in responding to changing business and economic conditions, including reacting to any changes in the relationships we have with our code-share partners.

	Your right to receive payments on the notes is effectively subordinated to the rights of our and the guarantors’ existing and future secured creditors. The notes, in certain other circumstances, may effectively be subordinated to any existing and future liabilities of Mesa Air and its subsidiaries.

      Holders of our secured indebtedness and the secured indebtedness of the guarantors will have claims that are senior to your claims as holders of the notes to the extent of the value of the assets securing that other indebtedness. The notes are effectively subordinated to our secured indebtedness. In the event of any distribution or payment of our assets in any foreclosure, dissolution, winding-up, liquidation, reorganization, or other bankruptcy proceeding, holders of secured indebtedness will have prior claim to those assets that constitute their collateral. Holders of the notes will participate ratably with all holders of our unsecured indebtedness that is deemed to be of the same class as the notes, and potentially with all of our other general creditors, based upon the respective amounts owed to each holder or creditor, in our remaining assets. In any of the foregoing events, we cannot assure you that there will be sufficient assets to pay amounts due on the notes. As a result, holders of notes may receive less, ratably, than holders of secured indebtedness.

      As of March 31, 2004, the aggregate amount of our and our subsidiaries’ senior secured indebtedness was $401.5 million, which primarily consisted of $253.9 million in notes payable related to 11 of our CRJ-700 and

7

---

 

      In addition, the notes are effectively subordinated to all existing and future liabilities, including claims with respect to trade payables, of any subsidiary which is not a guarantor of the notes. All of our existing wholly-owned domestic subsidiaries are guarantors of the notes and all future wholly-owned domestic subsidiaries will be required to guarantee the notes. In addition, our wholly-owned foreign subsidiary, MAGI Insurance, Ltd., is a guarantor of the notes on an unsecured senior basis and we may, in certain circumstances, add any newly formed or acquired wholly-owned foreign subsidiaries as guarantors in the future. Each of our other non-domestic subsidiaries and non-wholly-owned domestic subsidiaries will be required to guarantee the notes only so long as such subsidiary guarantees other indebtedness of ours. As a result, in the future, we may have subsidiaries that are not guarantors of the notes.

      Furthermore, if we fail to deliver our common stock upon conversion of a note and thereafter become the subject of bankruptcy proceedings, a holder’s claim for damages arising from such failure could be subordinated to all of our and our subsidiaries’ existing and future obligations.

	Our financial results may be adversely impacted if we are subsequently held liable for the obligations of our former subsidiary CCAir, Inc.

      In the fourth quarter of fiscal 2002 we established a reserve related to CCAir of $19.8 million for restructuring and impairment charges. Of these restructuring charges, $12.0 million was subsequently reversed in the second quarter of fiscal 2003, upon the determination, after consultation with counsel, that we are not liable for the aircraft lease obligations and aircraft related return costs incurred solely by CCAir and not guaranteed by us. In the event this determination is challenged and we are subsequently determined to be liable for such CCAir obligations, our financial results and our ability to make payments on the notes could be adversely impacted.

	We are a holding company, and we may not have access to the cash flow and other assets of the subsidiaries that may be needed to make payment on the notes.

      Although substantially all of our business is conducted through our subsidiaries, none of our subsidiaries is obligated to make funds available to us for payment on our indebtedness, including the notes. Accordingly, our ability to make payments on the notes is dependent on the earnings and the distribution of funds from our subsidiaries. Furthermore, the guarantors are permitted under the terms of our indebtedness to incur additional indebtedness that may severely restrict or prohibit the making of distributions, the payment of dividends or the making of loans by the guarantors to us. We cannot assure you that the agreements governing the current and future indebtedness of the guarantors will permit the guarantors to provide us with sufficient dividends, distributions or loans to fund payments on these notes when due.

	The notes have been issued at a substantial discount from their principal amount and, therefore, trigger certain U.S. federal income tax consequences for the holders of the notes.

      The notes have been issued at a substantial discount from their principal amount. Consequently, the notes are treated as issued with original issue discount for U.S. federal income tax purposes and you will be required to include such original issue discount in your gross income as it accrues for U.S. federal income tax purposes in advance of receipt of any payment on the notes to which the original issue discount is attributable. To understand how this may affect you, you should seek advice from your own tax advisor prior to purchasing these notes. See “Certain United States Federal Income Tax Considerations” for a more detailed discussion of the U.S. federal income tax consequences to the holders of the notes of the purchase, ownership and disposition of the notes.

	We may not have the ability to purchase the notes at the option of the holders upon certain changes in control or to raise the funds necessary to finance such purchases.

      Upon the occurrence of certain specific kinds of change of control events, we will be required to offer to purchase all outstanding notes. We may not have or be able to raise sufficient funds to make the required purchase of notes.

	Federal and state statutes allow courts, under specific circumstances, to void guarantees and require note holders to return payments received from guarantors.

      Under the federal bankruptcy law and comparable provisions of state fraudulent transfer laws, a guarantee could be voided, or claims in respect of a guarantee could be subordinated to all other debts of that guarantor, if, among other things, at the time it incurred the indebtedness evidenced by its guarantee, the guarantor received less than reasonably equivalent value or fair consideration for the incurrence of such guarantee and the guarantor

	•	was insolvent or rendered insolvent by reason of such incurrence;
	•	was engaged in a business or transaction for which the guarantor’s remaining assets constituted unreasonably small capital; or
	•	intended to incur, or believed that it would incur, debts beyond its ability to pay such debts as they mature.

      In addition, any payment by that guarantor pursuant to its guarantee could be voided and required to be returned to the guarantor, or to a fund for the benefit of the creditors of the guarantor.

      The measures of insolvency for purposes of these fraudulent transfer laws will vary depending upon the law applied in any proceeding to determine whether a fraudulent transfer has occurred. Generally, however, a guarantor would be considered insolvent if:

	•	the sum of its debts, including contingent liabilities, was greater than the fair saleable value of all of its assets;
	•	if the present fair saleable value of its assets was less than the amount that would be required to pay its probable liability on its existing debts, including contingent liabilities, as they become absolute and mature; or
	•	it could not pay its debts as they become due.

      On the basis of historical financial information, recent operating history and other factors, we believe that each guarantor, after giving effect to its guarantee of these notes, will not be insolvent, will not have unreasonably small capital for the business in which it is engaged and will not have incurred debts beyond its ability to pay such debts as they mature. We cannot assure you, however, as to what standard a court would apply in making these determinations or that a court would agree with our conclusions in this regard.

	An active trading market for the notes may not develop, and transfers of the notes may be restricted.

      The notes comprise a new issue of securities for which there is currently no public market. The notes will not be listed on any securities exchange or other stock market or included in any automated quotation system. We do not know whether an active trading market will develop for the notes. If the notes are traded after their initial issuance, they may trade at a discount from their initial offering price depending on prevailing interest rates, the market for similar securities, the price of our common stock, the performance of our common stock in the marketplace, our performance as a company and other factors.

      After we have registered the notes and the shares of underlying common stock, we will have the right, pursuant to the registration rights agreement, to suspend the use of the shelf registration statement in certain circumstances. In the event of such a suspension, you would not be able to sell any notes or shares of common stock issuable upon conversion of the notes.

Risks Related to Our Business

	The negative impact of the September 11, 2001 terrorist attacks and the resulting government responses could be material to our financial condition, results of operations and prospects.

      The terrorist attacks of September 11, 2001 were highly publicized. The impacts that these events will continue to have on the airline industry in general, and on us in particular, are not known at this time, but are expected to include a substantial impact on our operations due to:

	•	a reduction in the demand for travel in the near and mid-term until public confidence in the air transportation system is restored;
	•	an increase in costs due to enhanced security measures and government directives in response to the terrorist attacks;
	•	an increase in the cost of aviation insurance in general, and the cost and availability of coverage for acts of war, terrorism, hijacking, sabotage and similar acts of peril in particular; and
	•	an increase in airport rents and landing fees.

      In addition, we expect that the general increase in hostilities relating to reprisals against terrorist organizations and the continued threat of further terrorist attacks will continue to negatively impact our revenues and costs in the near and mid-term. The extent of the impact that the terrorist attacks and their aftermath will have on our operations, and the sufficiency of our financial resources to absorb this impact, will depend on a number of factors, including:

	•	the adverse impact that terrorist attacks, and the resulting government responses, will have on the travel industry and the economy in general;
	•	the potential increase in fuel costs and decrease in availability of fuel if oil-producing countries are affected by the aftermath of the terrorist attacks, including the government’s responses, and our ability to manage this risk in connection with that part of our operations where our fuel costs are not reimbursed by our code-share partners under the terms of our code-share agreements;
	•	our ability to reduce our operating costs and conserve financial resources, taking into account the cost increases (including significant increases in the cost of aviation insurance) expected to result from the aftermath of the terrorist attacks and the government’s responses;
	•	any resulting decline in the value of the aircraft in our fleet;
	•	our ability to raise additional financing, if necessary, taking into account our current leverage and the limitations imposed by the terms of our existing indebtedness;
	•	the number of crew members who may be called for duty in the reserve forces of the armed services and the resulting impact on our ability to operate as planned; and
	•	the scope and nature of any future terrorist attacks.

	We are dependent on our agreements with our code-share partners.

      We depend on relationships created by our code-share agreements. We derive a significant portion of our consolidated passenger revenues from our revenue-guarantee code-share agreements with America West, United Airlines, and US Airways. Our code-share partners have certain rights to cancel the applicable code-share agreement upon the occurrence of certain events or the giving of appropriate notice, subject to certain conditions. Although no notice has been given to date that any party intends to cancel these contracts, there can be no assurance that they will not serve notice at a later date of their intention to cancel, forcing us to stop selling those routes with the applicable partner’s code and potentially reducing our traffic and revenue. In addition, our code-share agreement with America West allows America West, subject to certain restrictions, to reduce the combined CRJ fleets utilized under the code-share agreement by one aircraft in any six-month period commencing in January 2007. In addition, beginning in February 2007, America West may eliminate

10

      In addition, because a majority of our operating revenues are currently generated under revenue-guarantee code-share agreements, if any one of them is terminated, our operating revenues and net income could be materially adversely affected unless we are able to enter into satisfactory substitute arrangements or, alternatively, fly under our own flight designator code, including obtaining the airport facilities and gates necessary to do so. In 2002 and 2003 and the six months ended March 31, 2003 and 2004, our America West code-share agreement accounted for 40%, 44%, 46% and 37%, respectively, of our consolidated passenger revenues and our US Airways code-share agreement accounted for 55%, 49%, 49% and 45%, respectively, of our consolidated passenger revenues. Any material modification to, or termination of, our code-share agreements with any of these partners could have a material adverse effect on our financial condition, the results of our operations and the price of our common stock. In addition, Mesa Airlines began operating as United Express in July 2003 under a revenue-guarantee code-share agreement with United Airlines. Should any of our revenue-guarantee code-share agreements be terminated, we cannot assure you that we would be able to enter into substitute code-share arrangements, that any such arrangements would be as favorable to us as the current code-share agreements or that we could successfully fly under our own flight designator code.

	If our code-share partners or other regional carriers experience events that negatively impact their financial strength or operations, our operations also may be negatively impacted.

      We are directly affected by the financial and operating strength of our code-share partners. Any events that negatively impact the financial strength of our code-share partners or have a long-term effect on the use of our code-share partners by airline travelers would likely have a material adverse effect on our business, financial condition and results of operations. In the event of a decrease in the financial or operational strength of any of our code-share partners, such partner may seek to reduce, or be unable to make, the payments due to us under their code-share agreement. In addition, they may reduce utilization of our aircraft. Although there are certain monthly guaranteed payment amounts, there are no minimum levels of utilization specified in the code-share agreements. UAL Corp., the parent of our code-share partner United Airlines, has filed petitions for reorganization under Chapter 11 of the U.S. Bankruptcy Code. Additionally, US Airways, which accounted for 49% of our consolidated passenger revenue in 2003, had its corporate credit rating reduced to ‘CCC+’ from ‘B-’ by Standard & Poor’s on May 5, 2004. The financial performance of US Airways could directly affect their ability to perform under our code-share agreement with them. If any of our code-share partners, including US Airways, becomes bankrupt, our code-share agreement with such partner may not be assumed in bankruptcy and would be terminated. This and other such events could have an adverse effect on our business, financial condition and results of operations. In addition, any negative events that occur to other regional carriers and that affect public perception of such carriers generally could also have a material adverse effect on our business, financial condition and results of operations.

	Our code-share partners may expand their direct operation of regional jets thus limiting the expansion of our relationships with them.

      We depend on major airlines like America West, United Airlines and US Airways electing to contract with us instead of purchasing and operating their own regional jets. However, these major airlines possess the resources to acquire and operate their own regional jets instead of entering into contracts with us or other regional carriers. We have no guarantee that in the future our code-share partners will choose to enter into contracts with us instead of purchasing their own regional jets or entering into relationships with competing regional airlines. A decision by America West, United Airlines, US Airways or any other code-share partners to phase out our contract-based code-share relationships or to enter into similar agreements with one or more of our competitors could have a material adverse effect on our business, financial condition or results of operations. In addition to Mesa Airlines, US Airways and United Airlines have similar code-share agreements with other competing regional airlines. Mesa Airlines is currently America West’s only code-share partner.

	If we experience a lack of labor availability or strikes, it could result in a decrease of revenues due to the cancellation of flights.

      The operation of our business is significantly dependent on the availability of qualified employees, including, specifically, flight crews, mechanics and avionics specialists. Historically, regional airlines have experienced high pilot turnover from time to time as a result of major air carriers hiring experienced commercial pilots away from regional carriers. Further, the addition of aircraft, especially new aircraft types, can result in pilots upgrading between aircraft types and becoming unavailable for duty during the required extensive training periods. There can be no assurance that we will be able to maintain an adequate supply of qualified personnel or that labor expenses will not increase as a result of a shortage in supply of such workers.

      At March 31, 2004 we had approximately 4,400 employees, a significant number of whom are members of various labor unions, including the Air Line Pilots Association and the Association of Flight Attendants. Our collective bargaining agreement with the Air Line Pilots Association expires in August 2007 and our collective bargaining agreement with the Association of Flight Attendants expires in June 2006. The inability to negotiate acceptable contracts with existing unions as agreements expire or with new unions could result in work stoppages by the affected workers, lost revenues resulting from the cancellation of flights and increased operating costs as a result of higher wages or benefits paid to union members. We cannot predict which, if any, other employee groups may seek union representation or the outcome or the terms of any future collective bargaining agreement and therefore the effect, if any, on our financial condition and results of operations. If negotiations with unions over collective bargaining agreements prove to be unsuccessful, following specified “cooling off” periods, the unions may initiate a work action, including a strike, which could have a material adverse effect on our business, financial condition and results of operations.

	Increases in our labor costs, which constitute a substantial portion of our total operating costs, will cause our earnings to decrease.

      Labor costs constitute a significant percentage of our total operating costs, and we have experienced pressure to increase wages and benefits for our employees. Under our code-share agreements, our reimbursement rates contemplate labor costs that increase on a set schedule generally tied to an increase in the consumer price index or the actual increase in the contract. We are responsible for our labor costs, and we may not be entitled to receive increased payments under our code-share agreements if our labor costs increase above the assumed costs included in the reimbursement rates. As a result, a significant increase in our labor costs above the levels assumed in our reimbursement rates could result in a material reduction in our earnings.

	If new airline regulations are passed or are imposed upon our operations, we may incur increased operating costs and experience a decrease in earnings.

      Laws and regulations, such as those described below, have been proposed from time to time that could significantly increase the cost of our operations by imposing additional requirements or restrictions on our operations. We cannot predict what laws and regulations will be adopted or what changes to air transportation agreements will be effected, if any, or how they will affect us, and there can be no assurance that laws or regulations currently proposed or enacted in the future will not increase our operating expenses and therefore adversely affect our financial condition and results of operations.

      As an interstate air carrier, we are subject to the economic jurisdiction, regulation and continuing air carrier fitness requirements of the Department of Transportation, which include required levels of financial, managerial and regulatory fitness. The Department of Transportation is authorized to establish consumer protection regulations to prevent unfair methods of competition and deceptive practices, to prohibit certain pricing practices, to inspect a carrier’s books, properties and records, to mandate conditions of carriage and to suspend an air carrier’s fitness to operate. The DOT also has the power to bring proceedings for the enforcement of air carrier economic regulations, including the assessment of civil penalties, and to seek criminal sanctions.

      We are also subject to the jurisdiction of the FAA with respect to our aircraft maintenance and operations, including equipment, ground facilities, dispatch, communication, training, weather observation,

12

---

 

      We incur substantial costs in maintaining our current certifications and otherwise complying with the laws, rules and regulations to which we are subject. We cannot predict whether we will be able to comply with all present and future laws, rules, regulations and certification requirements or that the cost of continued compliance will not significantly increase our costs of doing business.

      The FAA has the authority to issue mandatory orders relating to, among other things, the grounding of aircraft, inspection of aircraft, installation of new safety-related items and removal and replacement of aircraft parts that have failed or may fail in the future. A decision by the FAA to ground, or require time-consuming inspections of, or maintenance on, all or any of our turboprops or regional jets, for any reason, could negatively impact our results of operations.

      In addition to state and federal regulation, airports and municipalities enact rules and regulations that affect our operations. From time to time, various airports throughout the country have considered limiting the use of smaller aircraft, such as Embraer or Canadair regional jets, at such airports. The imposition of any limits on the use of our regional jets at any airport at which we operate could interfere with our obligations under our code-share agreements and severely interrupt our business operations.

	Fluctuations in fuel costs could adversely affect our operating expenses and results.

      The price and supply of jet fuel is unpredictable and fluctuates based on events outside our control, including geopolitical developments, regional production patterns and environmental concerns. Although approximately 84% and 90% of our fuel costs for the fiscal year ended September 30, 2003 and six months ended March 31, 2004, respectively, were reimbursed by our code-share partners, price escalations or reductions in the supply of jet fuel will increase our operating expenses and, to the extent such fuel costs are not reimbursed by our code-share partners, could cause our operating results and net income to decline.

	If additional security and safety measures regulations are adopted, we may incur increased operating costs and experience a decrease in earnings.

      Congress recently adopted increased safety and security measures designed to increase airline passenger security and protect against terrorist acts. Such measures have resulted in additional operating costs to the airline industry. The Aviation Safety Commission’s report recommends the adoption of further measures aimed at improving the safety and security of air travel. We cannot forecast what additional security and safety requirements may be imposed on our operations in the future or the costs or revenue impact that would be associated with complying with such requirements, although such costs and revenue impact could be significant. To the extent that the costs of complying with any additional safety and security measures are not reimbursed by our code-share partners, our operating results and net income could be adversely affected.

	If our operating costs increase as our aircraft fleet ages and we are unable to pass along such costs, our earnings will decrease.

      As our fleet of aircraft age, the cost of maintaining such aircraft, if not replaced, will likely increase. There can be no assurance that costs of maintenance, including costs to comply with aging aircraft requirements, will not materially increase in the future. Any material increase in such costs could have a material adverse effect on our business, financial condition and results of operations. Because many aircraft components are required to be replaced after specified numbers of flight hours or take-off and landing cycles, and because new aviation technology may be required to be retrofitted, the cost to maintain aging aircraft will generally exceed the cost to maintain newer aircraft. We believe that the cost to maintain our aircraft in the long-term will be consistent with industry experience for these aircraft types and ages used by comparable airlines.

      We believe that our aircraft are mechanically reliable based on the percentage of scheduled flights completed and as of March 31, 2004 the average age of our regional jet fleet is 2.85 years. However, there can be no assurance that such aircraft will continue to be sufficiently reliable over longer periods of time. Furthermore, any public perception that our aircraft are less than completely reliable could have a material adverse effect on our business, financial condition and results of operations.

	Our fleet expansion program will require a significant increase in our leverage and the financing we require may not be available on favorable terms or at all.

      The airline business is very capital intensive and, as a result, many airline companies are highly leveraged. During the fiscal years ended September 30, 2003 and 2002 and the six months ended March 31, 2004 and 2003, our debt service payments totaled $27.4 million, $19.1 million, $17.0 million and $14.7 million, respectively, and our lease payments totaled $130.4 million, $107.6 million, $83.5 million and $90.0 million, respectively. We have significant lease obligations with respect to our aircraft and ground facilities, which aggregated approximately $2.0 billion at March 31, 2004. As of March 31, 2004, our growth strategy involves the acquisition of 16 more Bombardier regional jets during fiscal 2004. As of March 31, 2004, the Company had permanently financed 30 of the 31 CRJ-700 and CRJ-900 aircraft delivered under the 2001 BRAD agreement; the remaining aircraft is subject to interim financing. Subsequent to quarter end, the Company took delivery of six additional Bombardier CRJ-900 aircraft that were subject to interim financing. The Company has the ability to fund up to 15 aircraft at one time on interim financing provided by the manufacturer. Its ability to obtain additional interim financing is contingent upon obtaining permanent financing for the aircraft already delivered. There are no assurances the Company will be able to obtain permanent financing for future aircraft deliveries. If we are able to obtain financing for these aircraft, it will significantly increase our mandatory lease and debt service payments.

      There can be no assurance that our operations will generate sufficient cash flow to make such payments or that we will be able to obtain financing to acquire the additional aircraft necessary for our expansion. If we default under our loan or lease agreements, the lender/lessor has available extensive remedies, including, without limitation, repossession of the respective aircraft and, in the case of large creditors, the effective ability to exert control over how we allocate a significant portion of our revenues. Even if we are able to timely service our debt, the size of our long-term debt and lease obligations could negatively affect our financial condition, results of operations and the price of our common stock in many ways, including:

	•	increasing the cost, or limiting the availability of, additional financing for working capital, acquisitions or other purposes;
	•	limiting the ways in which we can use our cash flow, much of which may have to be used to satisfy debt and lease obligations; and
	•	adversely affecting our ability to respond to changing business or economic conditions or continue our growth strategy.

      If we need funds and cannot raise them on acceptable terms, we may be unable to realize our current plans or take advantage of unanticipated opportunities and could be required to slow our growth.

	We depend on Bombardier to supply us with the aircraft we require to expand.

      As of March 31, 2004, we are obligated under our code-share agreements to place an additional 37 regional jets in service over the next 12 months. We currently have firm orders with Bombardier for an additional 23 regional jets. We also have options to acquire an additional 60 regional jets that are exercisable through 2008.

      We are dependent on Bombardier as manufacturer of these jets and certain factors may limit or preclude our ability to obtain these regional jets, including:

	•	Bombardier could refuse, or may not be financially able, to perform its obligations under the applicable purchase agreement for the delivery of the regional jets; and

14

---

 

	•	a fire, strike or other event could occur that affects Bombardier’s ability to completely or timely fulfill its contractual obligations.

      Any disruption or change in the delivery schedule of these regional jets would affect our overall operations and our ability to fulfill our obligations under our code-share agreements.

      Our operations could be materially adversely affected by the failure or inability of Bombardier or any key component manufacturers to provide sufficient parts or related support services on a timely basis or by an interruption of fleet service as a result of unscheduled or unanticipated maintenance requirements for our aircraft.

	Reduced utilization levels of our aircraft under the revenue-guarantee agreements would adversely impact our revenues and earnings.

      Even though our revenue-guarantee agreements require a fixed amount per month to compensate us for our fixed costs, if our aircraft are underutilized (including taking into account the stage length and frequency of our scheduled flights) we will lose the opportunity to receive a margin on the variable costs of flights that would have been flown if our aircraft were more fully utilized.

	If we incur problems with any of our third party service providers, our operations could be adversely affected by a resulting decline in revenue or negative public perception about our services.

      Our reliance upon others to provide essential services on behalf of our operations may result in the relative inability to control the efficiency and timeliness of contract services. We have entered into agreements with contractors to provide various facilities and services required for our operations, including aircraft maintenance, ground facilities, baggage handling and personnel training. It is likely that similar agreements will be entered into in any new markets we decide to serve. All of these agreements are subject to termination after notice. Any material problems with the efficiency and timeliness of contract services could have a material adverse effect on our business, financial condition and results of operations.

	If any of our existing litigation with Atlantic Coast Airlines or related regulatory inquiries are concluded in a manner adverse to us, our business could be adversely affected.

      In October 2003, we announced that we had made an unsolicited proposal to the board of directors of Atlantic Coast Airlines Holdings, Inc. (“Atlantic Coast”) to acquire all the outstanding stock of Atlantic Coast.

      Following this unsolicited proposal, several lawsuits were filed by Atlantic Coast and anti-trust investigations were initiated by the Department of Justice and the Corporation Counsel for the District of Columbia. On December 23, 2003, we announced that we would not be moving forward with our proposed offer for Atlantic Coast. As a result of this announcement, the United States Department of Justice and Corporation Counsel dropped their antitrust investigations. Despite this decision, our litigation with Atlantic Coast remains pending. Until a final determination or dismissal is issued by the United States District Court for the District of Columbia, the Company faces the possibility of an adverse result which could have a negative impact on our business.

	We are at risk of losses and adverse publicity stemming from any accident involving any of our aircraft.

      If one of our aircraft were to crash or be involved in an accident, we could be exposed to significant tort liability. In this regard, in January 2003 US Airways Flight 5481, operated by our subsidiary Air Midwest,

15

---

 

      The estates of the passengers from Flight 5481, or the passengers, or their estates, of any other future aircraft accident may seek to recover damages for death or injury. Although we believe our present insurance coverage is sufficient to cover any claims arising from the crash of Flight 5481, there can be no assurance that the insurance we carry to cover damages arising from these or any future accidents will be adequate. Accidents could also result in unforeseen mechanical and maintenance costs. In addition, any accident involving an aircraft that we operate could create a public perception that our aircraft are not safe, which could result in air travelers being reluctant to fly on our aircraft. To the extent a decrease is associated with our operations not covered by our code- share agreements, such a decrease could have a material adverse affect on our business, financial condition or results of operations.

      We are also subject to ongoing investigations by the FAA and the National Transportation Safety Board with respect to the events surrounding the crash of Flight 5481. The imposition of substantial civil penalties, with respect to Flight 5481 or any other aircraft accident, would have a material adverse impact on our earnings.

	If we become involved in any material litigation or any existing litigation is concluded in a manner adverse to us, our earnings may decline.

      We are, from time to time, subject to various legal proceedings and claims, either asserted or unasserted. Any such claims, whether with or without merit, could be time-consuming and expensive to defend and could divert management’s attention and resources. There can be no assurance regarding the outcome of current or future litigation.

	Our business would be harmed if we lose the services of our key personnel.

      Our success depends to a large extent on the continued service of our executive management team. We have employment agreements with certain executive officers, but it is possible that members of executive management may leave us. Departures by our executive officers could have a negative impact on our business, as we may not be able to find suitable management personnel to replace departing executives on a timely basis. We do not maintain key-man life insurance on any of our executive officers.

	We may experience difficulty finding, training and retaining employees.

      Our business is labor-intensive, we require large numbers of pilots, flight attendants, maintenance technicians and other personnel and we anticipate that our expansion plans will require us to recruit, train and retain a significant number of new employees over the next several years.

      The airline industry has from time to time experienced a shortage of qualified personnel, specifically pilots and maintenance technicians. In addition, as is common with most of our competitors, we have faced considerable turnover of our employees. Although our employee turnover has decreased significantly since September 11, 2001, our pilots, flight attendants and maintenance technicians often leave to work for larger airlines, which generally offer higher salaries and better benefit programs than regional airlines are financially able to offer. Should the turnover of employees, particularly pilots and maintenance technicians, sharply increase, the result will be significantly higher training costs than otherwise would be necessary. We cannot assure you that we will be able to recruit, train and retain the qualified employees that we need to carry out our expansion plans or replace departing employees. If we are unable to hire and retain qualified employees at a reasonable cost, we may be unable to complete our expansion plans, which could have a material adverse affect our financial condition, results of operations and the price of our common stock.

Risks Related To Our Industry

	If competition in the airline industry increases, we may experience a decline in revenue.

      Increased competition in the airline industry as well as competitive pressure on our code-share partners or in our markets could have a material adverse effect on our business, financial condition and results of operation. The airline industry is highly competitive. The earnings of many of the airlines have historically been volatile. The airline industry is susceptible to price discounting, which involves the offering of discount or promotional fares to passengers. Any such fares offered by one airline are normally matched by competing airlines, which may result in lower revenue per passenger, i.e., lower yields, without a corresponding increase in traffic levels. Also, in recent years several new carriers have entered the industry, typically with low cost structures. In some cases, new entrants have initiated or triggered price discounting. The entry of additional new major or regional carriers in any of our markets, as well as increased competition from or the introduction of new services by established carriers, could negatively impact our financial condition and results of operations.

      Our reliance on our code-share agreements with our major airline partners for the majority of our revenue means that we must rely on the ability of our code-share partners to adequately promote their respective services and to maintain their respective market share. Competitive pressures by low-fare carriers and price discounting among major airlines could have a material adverse effect on our code-share partners and therefore adversely affect our business, financial condition and results of operations.

      The results of operations in the air travel business historically fluctuate in response to general economic conditions. The airline industry is sensitive to changes in economic conditions that affect business and leisure travel and is highly susceptible to unforeseen events, such as political instability, regional hostilities, economic recession, fuel price increases, inflation, adverse weather conditions or other adverse occurrences that result in a decline in air travel. Any event that results in decreased travel or increased competition among airlines could have a material adverse effect on our business, financial condition and results of operations.

      In addition to traditional competition among airlines, the industry faces competition from ground and sea transportation alternatives. Video teleconferencing and other methods of electronic communication may add a new dimension of competition to the industry as business travelers seek lower-cost substitutes for air travel.

	The airline industry is heavily regulated.

      Airlines are subject to extensive regulatory and legal compliance requirements, both domestically and internationally, that involve significant costs. In the last several years, the FAA has issued a number of directives and other regulations relating to the maintenance and operation of aircraft that have required us to make significant expenditures. FAA requirements cover, among other things, retirement of older aircraft, security measures, collision avoidance systems, airborne windshear avoidance systems, noise abatement, commuter aircraft safety and increased inspection and maintenance procedures to be conducted on older aircraft.

      We incur substantial costs in maintaining our current certifications and otherwise complying with the laws, rules and regulations to which we are subject. We cannot predict whether we will be able to comply with all present and future laws, rules, regulations and certification requirements or that the cost of continued compliance will not significantly increase our costs of doing business, to the extent such costs are not reimbursed by our code-share partners.

      The FAA has the authority to issue mandatory orders relating to, among other things, the grounding of aircraft, inspection of aircraft, installation of new safety-related items and removal and replacement of aircraft parts that have failed or may fall in the future. A decision by the FAA to ground, or require time consuming inspections of or maintenance on, all or any of our aircraft, for any reason, could negatively impact our results of operations.

      In addition to state and federal regulation, airports and municipalities enact rules and regulations that affect our operations. From time to time, various airports throughout the country have considered limiting the

17

---

 

      Additional laws, regulations, taxes and airport rates and charges have been proposed from time to time that could significantly increase the cost of airline operations or reduce revenues. For instance, “passenger bill of rights” legislation was introduced in Congress in 2001 which would have, among other things, required the payment of compensation to passengers as a result of certain delays and limited the ability of carriers to prohibit or restrict usage of certain tickets. If adopted, these measures could have had the effect of raising ticket prices, reducing revenue and increasing costs. Restrictions on the ownership and transfer of airline routes and takeoff and landing slots have also been proposed. In addition, as a result of the terrorist attacks in New York and Washington, D.C. in September 2001, the FAA has imposed more stringent security procedures on airlines. We cannot predict what other new regulations may be imposed on airlines and we cannot assure you that laws or regulations enacted in the future will not materially adversely affect our financial condition, results of operations and the price of our common stock.

	The airline industry has been subject to a number of strikes which could affect our business.

      The airline industry has been negatively impacted by a number of labor strikes. Any new collective bargaining agreement entered into by other regional carriers may result in higher industry wages and add increased pressure on us to increase the wages and benefits of our employees. Furthermore, since each of our code-share partners is a significant source of revenue, any labor disruption or labor strike by the employees of any one of our code-share partners could have a material adverse effect on our financial condition, results of operations and the price of our common stock.

Risks Related to Our Common Stock

	Provisions in our charter documents might deter acquisition bids for us.

      Our articles of incorporation and bylaws contain provisions that, among other things:

	•	authorize our board of directors to issue preferred stock ranking senior to our common stock without any action on the part of the shareholders;
	•	establish advance notice procedures for shareholder proposals, including nominations of directors, to be considered at shareholders’ meetings;
	•	authorize a majority of our board of directors, in certain circumstances, to fill vacancies on the board resulting from an increase in the authorized number of directors or from vacancies;
	•	restrict the ability of shareholders to modify the number of authorized directors; and
	•	restrict the ability of stockholders to call special meetings of shareholders.

      In addition, Section 78.438 of the Nevada general corporation law prohibits us from entering into some business combinations with interested stockholders without the approval of our board of directors. These provisions could make it more difficult for a third party to acquire us, even if doing so would benefit our stockholders.

	Our stock price may continue to be volatile and could decline substantially.

      The stock market has, from time to time, experienced extreme price and volume fluctuations. Many factors may cause the market price for our common stock to decline following this offering, including:

	•	our operating results failing to meet the expectations of securities analysts or investors in any quarter;
	•	downward revisions in securities analysts’ estimates;
	•	material announcements by us or our competitors;

18

	•	public sales of a substantial number of shares of our common stock following this offering;
	•	governmental regulatory action; or
	•	adverse changes in general market conditions or economic trends.

RATIO OF EARNINGS TO FIXED CHARGES

      The ratio of earnings to fixed charges for each of the periods indicated is as follows:

		Year Ended September 30
																						Six Months ended				Six Months ended
		1999				2000				2001				2002				2003				March 31, 2003				March 31, 2004
Ratio of earnings to fixed charges (deficiency)			(*	)			1.71				(*	)			(*	)			1.72				1.65				1.24

---

(*)	Earnings were insufficient to cover fixed charges by $12.8 million, $72.5 million, and $17.4 million for the fiscal years ended September 30, 1999, 2001 and 2002, respectively.

      For purposes of calculating this ratio, earnings consist of earnings before taxes, minority interest and extraordinary items plus interest expense (net of capitalized interest) and the portion of rental expense deemed representative of the interest expense. Fixed charges consist of interest expense, the portion of rental expense representative of interest expense and capitalized interest.

USE OF PROCEEDS

      We will not receive any proceeds from the sale of the notes or shares underlying the notes by the selling securityholders. We received net proceeds from the sale of the notes of approximately $97.0 million, after deducting estimated discounts and commissions for initial purchasers and estimated fees and expenses associated with the offering. We used, or plan to use, the net proceeds of the offering for general corporate purposes and to fund obligations with respect to future regional jet deliveries.

DESCRIPTION OF THE NOTES

      We issued the notes under an indenture dated as of February 10, 2004, between us, as issuer, the guarantors and U.S. Bank National Association, as trustee. The notes constitute senior debt securities under the indenture. The following summarizes the material provisions of the notes. The following description does not purport to be complete and is subject to, and qualified by reference to, all of the provisions of the indenture and the notes, which we urge you to read because they define your rights as a notes holder. A copy of the indenture is available upon request to us. As used in this description of the notes, the words “we,” “us,” “our,” “Mesa” or “Mesa Air” refer only to Mesa Air Group, Inc. and do not include any current or future subsidiary of Mesa Air Group, Inc.

General

      The notes are limited to $171,409,000 aggregate principal amount at maturity. The notes will mature on February 10, 2024. The principal amount at maturity of each note will be $1,000. The notes are payable at the principal corporate trust office of the paying agent, which initially will be an office or agency of the trustee, or an office or agency maintained by us for such purpose, in the Borough of Manhattan, The City of New York.

      The notes bear cash interest at the rate of 2.115% per year on the principal amount at maturity from the issue date, or from the most recent date to which interest has been paid or provided for, until February 10, 2009. During such period, cash interest is payable semiannually in arrears on February 10 and August 10 of each year, commencing on August 10, 2004, to holders of record at the close of business on February 1 or August 1 immediately preceding such interest payment date. Each payment of cash interest on the notes includes interest accrued through the day before the applicable interest payment date (or purchase, redemption or, in certain circumstances, conversion date, as the case may be). Any payment required to be made on any day that is not a business day will be made on the next succeeding business day.

      The notes were offered at a substantial discount from their $1,000 principal amount at maturity. The notes were issued at an issue price of $583.40 per note. Beginning February 10, 2009, the notes will accrue original issue discount while they remain outstanding at a rate of 3.625% per year. Original issue discount is the difference between the issue price and the principal amount (or stated redemption price for federal income tax purposes) at maturity of a note. The calculation of the accrual of original issue discount will be on a semiannual bond equivalent basis, using a 360-day year composed of twelve 30-day months. For United States federal income tax purposes, the stated redemption price at maturity of the notes will include the semiannual cash interest payments payable through February 10, 2009 and original issue discount will accrue at a constant rate of 3.625% per year, calculated on a semiannual bond equivalent basis throughout the term of the notes from February 10, 2009. Thus, holders will be required to accrue the cash interest as original issue discount regardless of their method of tax accounting but will not recognize any income when such interest is actually paid. See “Certain United States Federal Income Tax Considerations — U.S. Holders — Original Issue Discount.”

      Original issue discount or cash interest, as the case may be, will cease to accrue on a note upon its maturity, conversion, purchase by us at the option of a holder or redemption. We may not reissue a note that has matured or been converted, purchased by us at your option, redeemed or otherwise cancelled, except for registration of transfer, exchange or replacement of such note.

      Notes may be presented for conversion at the office of the conversion agent and for exchange or registration of transfer at the office of the registrar. The conversion agent and the registrar shall initially be the trustee. No service charge will be made for any registration of transfer or exchange of notes. However, we may require the holder to pay any tax, assessment or other governmental charge payable as a result of such transfer or exchange.

Ranking of the Notes

      The notes are senior unsecured obligations and rank equal in right of payment to all of our other senior unsecured and unsubordinated indebtedness. The notes are effectively subordinated to our secured indebted-

20

---

 

Guarantees

      We have caused each of our wholly-owned domestic subsidiaries, including any person that becomes a wholly-owned domestic subsidiary after the date of the indenture, to be a guarantor under the indenture, for so long as such subsidiary guarantees other indebtedness of ours. As of the date hereof, all of our wholly-owned domestic subsidiaries are guarantors of our notes.

      The guarantors jointly and severally guarantee our obligations under the notes on an unsecured senior basis. Each guarantee of a guarantor will be equal in right of payment to all existing and future unsecured and unsubordinated indebtedness of such guarantor. The guarantees are effectively subordinated to the guarantors’ secured indebtedness to the extent of the security. As of March 31, 2004, the guarantors had an aggregate of $401.5 million of senior secured indebtedness outstanding (other than the notes), which primarily consisted of $253.9 million of notes payable related to 11 of our CRJ-700 and CRJ-900 aircraft, $25.3 million of notes payable on interim financing of regional jets, $97.5 million of notes payable related to our fleet of Beechcraft 1900D turboprop aircraft, $23.8 million in notes payable related to two CRJ-200 aircraft and $1.0 million related to a mortgage note payable on one of our real estate properties. We also had $11.6 million in letters of credit outstanding at March 31, 2004. The obligation of each guarantor under its guarantee will be limited to the greatest amount that would not render its obligations under the guarantee subject to avoidance as fraudulent conveyance or fraudulent transfer under applicable law.

      Each guarantor that makes payment or distribution of more than its proportionate share under a guarantee shall be entitled to contribution from each other such guarantor that has not paid its proportionate share of such payment or distribution.

      The indenture provides that so long as no default exists or would exist, the guarantee issued by any guarantor shall be automatically and unconditionally released and discharged upon any sale to any person that is not affiliated with us of all of the capital stock of such guarantor owned, directly or indirectly, by us which transaction is otherwise in compliance with the indenture. The indenture also provides that any non-domestic subsidiaries and non-wholly-owned domestic subsidiaries will only be required to guarantee the notes until such time as such subsidiary no longer guarantees any of our indebtedness (other than the notes), at which time such guarantee by such subsidiary will be released and discharged. If, however, such subsidiary subsequently guarantees any of our indebtedness (other than the notes), the guarantee by such subsidiary will be reinstated.

Conversion Rights

      A holder may convert a note, in multiples of $1,000 principal amount at maturity, into common stock only if at least one of the conditions described below is satisfied. In addition, a holder may convert a note only until the close of business on the second business day prior to the redemption date if we call a note for redemption. A note for which a holder has delivered a purchase notice or a change of control purchase notice requiring us to purchase the note may be surrendered for conversion only if such notice is withdrawn in accordance with the indenture.

      The initial conversion rate is 40.3737 shares of common stock per note, subject to adjustment upon the occurrence of certain events described below. A holder of a note otherwise entitled to a fractional share will receive cash equal to the applicable portion of the then current sale price of our common stock on the trading day immediately preceding the conversion date. Upon a conversion, we will have the option to deliver cash or a combination of cash and shares of our common stock as described below. The ability to surrender notes for conversion will expire at the close of business on February 10, 2024.

      To convert a note into shares of common stock, a holder must:

	•	complete and manually sign a conversion notice, a form of which is on the back of the note, and deliver the conversion notice to the conversion agent;

21

---

 

	•	surrender the note to the conversion agent;
	•	if required by the conversion agent, furnish appropriate endorsements and transfer documents; and
	•	if required, pay all transfer or similar taxes.

      On conversion of a note, a holder will not receive any cash payment of interest representing accrued original issue discount or, except as described below, accrued cash interest. Delivery to the holder of the full number of shares of common stock into which the note is convertible, together with any cash payment of such holder’s fractional shares, will be deemed:

	•	to satisfy our obligation to pay the principal amount at maturity of the note; and
	•	to satisfy our obligation to pay accrued original issue discount or accrued cash interest attributable to the period from the issue date through the conversion date.

      As a result, accrued original issue discount or accrued cash interest is deemed paid in full rather than cancelled, extinguished or forfeited. Notwithstanding the foregoing, accrued cash interest, if any, will be payable upon any conversion of notes at the option of the holder made concurrently with or after acceleration of the notes following an event of default described under “— Events of Default and Acceleration” below. Holders of notes surrendered for conversion during the period from the close of business on any regular record date next preceding any interest payment date to the opening of business of such interest payment date will receive the semiannual interest payable on such notes on the corresponding interest payment date notwithstanding the conversion and such notes (except notes called for redemption) upon surrender must be accompanied by funds equal to the amount of semiannual interest payable on the principal amount at maturity of notes so converted.

      The conversion rate will not be adjusted for accrued original issue discount or accrued cash interest. A certificate for the number of full shares of common stock into which any note is converted, together with any cash payment for fractional shares, will be delivered through the conversion agent as soon as practicable following the conversion date. For a discussion of the tax treatment of a holder receiving shares of our common stock upon surrendering notes for conversion, see “Certain United States Federal Income Tax Considerations — U.S. Holders — Conversion of Notes into Common Stock.”

      In lieu of delivery of shares of our common stock upon notice of conversion of any notes (for all or any portion of the notes), we may elect to pay holders surrendering notes an amount in cash per note (or a portion of a note) equal to the average sale price of our common stock for the five consecutive trading days immediately following either (a) the date of our notice of our election to deliver cash as described below if we have not given notice of redemption, or (b) the conversion date, in the case of conversion following our notice of redemption specifying that we intend to deliver cash upon conversion, in either case multiplied by the conversion rate in effect on that date. We will inform the holders through the trustee no later than two business days following the conversion date of our election to deliver shares of our common stock or to pay cash in lieu of delivery of the shares, unless we have already informed holders of our election in connection with our optional redemption of the notes as described under “— Redemption of Notes at Our Option.” If we elect to deliver all of such payment in shares of our common stock, the shares will be delivered through the conversion agent no later than the fifth business day following the conversion date. If we elect to pay all or a portion of such payment in cash, the payment, including any delivery of our common stock, will be made to holders surrendering notes no later than the tenth business day following the applicable conversion date. If an event of default, as described under “— Events of Default and Acceleration” below (other than a default in a cash payment upon conversion of the notes), has occurred and is continuing, we may not pay cash upon conversion of any notes or portion of a note (other than cash for fractional shares).

      We will adjust the conversion rate for:

	(1) dividends or distributions on our common stock payable in our common stock or other capital stock of Mesa Air;
	(2) subdivisions, combinations or certain reclassifications of our common stock;

22

---

 

	(3) distributions to all holders of our common stock of certain rights to purchase our common stock for a period expiring within 60 days of the record date for such issuance at less than the then-current sale price; and
	(4) distributions to the holders of our common stock of a portion of our assets (including shares of capital stock of a subsidiary) or debt securities issued by us or certain rights to purchase our securities (excluding cash dividends or other cash distributions from current or retained earnings unless the annualized amount thereof per share exceeds 15% of the sale price of our common stock on the day preceding the date of declaration of such dividend or other distribution).

However, no adjustment to the conversion rate need be made if holders of the notes may participate in the transaction without conversion or in certain other cases.

      In the event that we elect to make a distribution to all holders of shares of our common stock pursuant to clause (3) or clause (4) of the preceding paragraph, which, in the case of clause (4), has a per share value equal to more than 15% of the sale price of our shares of common stock on the day preceding the declaration date for such distribution, we will be required to give notice to the holders of notes at least 20 days prior to the date for such distribution and, upon the giving of such notice, the notes may be surrendered for conversion at any time until the close of business on the business day prior to the date of distribution or until we announce that such distribution will not take place.

      In addition, the indenture provides that upon conversion of the notes, the holders of such notes will receive, in addition to the shares of common stock issuable upon such conversion, the rights related to such common stock pursuant to any future shareholder rights plan, whether or not such rights have separated from the common stock at the time of such conversion. However, there shall not be any adjustment to the conversion privilege or conversion rate as a result of:

	•	the issuance of the rights;
	•	the distribution of separate certificates representing the rights;
	•	the exercise or redemption of such rights in accordance with any rights agreement; or
	•	the termination or invalidation of the rights.
	•	The indenture permits us to increase the conversion rate from time to time.

      Holders of the notes may, in certain circumstances, be deemed to have received a distribution subject to United States federal income tax as a dividend upon:

	•	a taxable distribution to holders of common stock which results in an adjustment of the conversion rate;
	•	an increase in the conversion rate at our discretion; or
	•	failure to adjust the conversion rate in some instances.

      See “Certain United States Federal Income Tax Considerations — U.S. Holders — Constructive Dividend.”

      If we are a party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of our assets, the right to convert a note into common stock may be changed into a right to convert it into the kind and amount of securities, cash or other assets of Mesa Air or another person which the holder would have received if the holder had converted the holder’s note immediately prior to the transaction.

      The conversion agent will, on our behalf, determine if the notes are convertible and notify the trustee and us accordingly. If one or more of the conditions to the conversion of the notes has been satisfied, we will promptly notify the holders of the notes thereof and use our reasonable best efforts to post this information on our website or otherwise publicly disclose this information.

      Conversion Based on Common Stock Price. Holders may surrender notes for conversion into our shares of common stock in any fiscal quarter commencing after March 31, 2004 if, as of the last day of the preceding

23

---

 

      The accreted conversion price per share as of any day will equal the issue price of a note plus the accrued original issue discount to that day, divided by the number of shares of common stock issuable upon conversion of a note on that day. The sale price of our common stock on any trading day means the closing per share sale price (or if no closing sale price is reported, the average of the bid and ask prices or, if more than one in either case, the average of the average bid and the average ask prices) on such date on the principal national securities exchange on which the common stock is listed or, if our common stock is not listed on a national securities exchange, as reported by the Nasdaq National Market or otherwise as provided in the indenture.

      The conversion trigger price per share of our common stock in respect of each of the first 20 fiscal quarters following issuance of the notes is $15.89. This conversion trigger price reflects the accreted conversion price per share of common stock multiplied by 110%. Thereafter, the accreted conversion price per share of common stock increases each fiscal quarter by the accreted original issue discount for the quarter. The conversion trigger price per share for the fiscal quarter beginning January 1, 2024 is $27.14. The foregoing conversion trigger prices assume that no events have occurred that would require an adjustment to the conversion rate.

      Conversion Based on Trading Price of the Notes. On or before February 10, 2019, a holder also may convert its notes into shares of our common stock at any time after a 10 consecutive trading-day period in which the average of the trading prices for the notes for that 10 trading-day period was less than 103% of the average conversion value for the notes during that period.

      The conversion value of a note is equal to the product of the closing sale price for shares of our common stock on a given day multiplied by the then current conversion rate, which is the number of shares of common stock into which each note is then convertible. The trading price of the notes on any date of determination is the average of the secondary market bid quotations per note obtained by us or the calculation agent for $2,500,000 principal amount of notes at approximately 3:30 p.m., New York City time, on such determination date from two independent nationally recognized securities dealers we select, provided that if at least two such bids cannot reasonably be obtained by us or the calculation agent, but one such bid is obtained, then this one bid shall be used.

      Conversion Based on Redemption. A holder may surrender for conversion a note called for redemption at any time prior to the close of business on the second business day immediately preceding the redemption date, even if it is not otherwise convertible at such time. A note for which a holder has delivered a purchase notice or a change of control purchase notice, as described below, requiring us to purchase such note may be surrendered for conversion only if such notice is withdrawn in accordance with the indenture.

      A “business day” is any weekday that is not a day on which banking institutions in The City of New York or the city in which the trustee’s corporate trust office is located are authorized or obligated to close. A “trading day” is any day on which the Nasdaq National Market is open for trading or, if the applicable security is not quoted on the Nasdaq National Market, a day on which trades may be made on the principal market the applicable security is then traded.

      Conversion upon Occurrence of Certain Corporate Transactions. If we are party to a consolidation, merger or binding share exchange or a transfer of all or substantially all of our assets, a note may be surrendered for conversion at any time from and after the date which is 15 days prior to the anticipated effective date of the transaction until 15 days after the actual effective date of such transaction, and at the effective date, the right to convert a note into common stock will be changed into a right to convert it into the kind and amount of securities, cash or other assets of Mesa Air or another person which the holder would have received if the holder had converted the holder’s notes immediately prior to the transaction. If such transaction

      The notes are also be convertible upon the occurrence of certain distributions resulting in an adjustment to the conversion price as described above.

Redemption of Notes at Our Option

      No sinking fund is provided for the notes. Prior to February 10, 2009, we cannot redeem the notes at our option. Beginning on February 10, 2009, we may redeem the notes for cash, as a whole at any time or from time to time in part. We will give not less than 30 days’ or more than 60 days’ notice of redemption by mail to holders of notes.

      If redeemed at our option, the notes will be redeemed at a price equal to the sum of the issue price plus accrued original issue discount and accrued cash interest, if any, on such notes to the applicable redemption date. The table below shows the redemption prices of a note on February 10, 2009, on each February 10 thereafter prior to maturity and at maturity on February 10, 2024. In addition, the redemption price of a note that is redeemed between the dates listed below would include an additional amount reflecting the additional accrued original issue discount that has accrued on such note since the immediately preceding date in the table below.

		(1)				(2)				(3)
		Note Issue				Accrued Original				Redemption
Redemption Date		Price				Issue Discount				Price (1) + (2)
2009		$	583.40			$	0.00			$	583.40
2010			583.40				21.34				604.74
2011			583.40				43.46				626.86
2012			583.40				66.39				649.79
2013			583.40				90.16				673.56
2014			583.40				114.80				698.20
2015			583.40				140.34				723.74
2016			583.40				166.81				750.21
2017			583.40				194.25				777.65
2018			583.40				222.70				806.10
2019			583.40				252.18				835.58
2020			583.40				282.75				866.15
2021			583.40				314.43				897.83
2022			583.40				347.27				930.67
2023			583.40				381.31				964.71
At stated maturity			583.40				416.60				1,000.00

      If we convert the notes to semiannual coupon notes following the occurrence of a tax event, the notes will be redeemable at the restated principal amount plus accrued and unpaid interest from the date of the conversion through the redemption date. However, in no event may the notes be redeemed prior to February 10, 2009. For more information on this optional conversion, see “Optional Conversion to Semiannual Coupon Notes upon Tax Event.”

      If less than all of the outstanding notes are to be redeemed, the trustee will select the notes to be redeemed in principal amounts at maturity of $1,000 or integral multiples of $1,000. In this case, the trustee may select the notes by lot, pro rata or by any other method the trustee considers fair and appropriate. If a portion of a holder’s notes is selected for partial redemption and the holder converts a portion of the notes, the converted portion will be deemed to be the portion selected for redemption.

Purchase of Notes at the Option of the Holder

      On the purchase dates of February 10, 2009, February 10, 2014 and February 10, 2019, we may, at the option of the holder, be required to purchase, at the purchase price set forth below plus accrued cash interest, if any, to the purchase date, any outstanding note for which a written purchase notice has been properly delivered by the holder and not withdrawn, subject to certain additional conditions. Holders may submit their written purchase notice to the paying agent at any time from the opening of business on the date that is 20 business days prior to such purchase date until the close of business on the business day immediately preceding such purchase date.

      The purchase price of a note will be:

	•	$583.40 per note on February 10, 2009;
	•	$698.20 per note on February 10, 2014; and
	•	$835.58 per note on February 10, 2019.

      The above purchase prices reflect a price equal to the sum of the issue price and accrued original issue discount, if any, on such notes as of the applicable purchase date.

      We may, at our option, elect to pay the purchase price in cash or shares of common stock, or any combination thereof. For a discussion of the tax treatment of a holder receiving cash, common stock or any combination thereof, see “Certain United States Federal Income Tax Considerations — U.S. Holders — Sale, Exchange, Redemption and Other Disposition of Notes” and “— Conversion of Notes into Common Stock.”

      If prior to a purchase date the notes have been converted to semiannual coupon notes following the occurrence of a tax event, the purchase price will be equal to the restated principal amount plus accrued and unpaid cash interest from the date of the conversion to the purchase date. For more information on this optional conversion, see “— Optional Conversion to Semiannual Coupon Notes upon Tax Event.”

      We will be required to give notice on a date not less than 20 business days prior to each purchase date to all holders at their addresses shown in the register of the registrar, and to beneficial owners as required by applicable law, stating among other things:

	•	the amount of the purchase price;
	•	whether we will pay the purchase price of the notes in cash or common stock or any combination thereof, specifying the percentages of each;
	•	if we elect to pay in common stock, the calculation of the market price of the common stock; and
	•	the procedures that holders must follow to require us to purchase their notes.

      The purchase notice given by each holder electing to require us to purchase notes shall state:

	•	the certificate numbers of the holder’s notes to be delivered for purchase;
	•	the portion of the principal amount at maturity of notes to be purchased, which must be $1,000 or an integral multiple of $1,000;
	•	that the notes are to be purchased by us pursuant to the applicable provisions of the notes; and
	•	in the event we elect, pursuant to the notice that we are required to give, to pay the purchase price in common stock, in whole or in part, but the purchase price is ultimately to be paid to the holder entirely in cash because any of the conditions to payment of the purchase price or portion of the purchase price in common stock is not satisfied prior to the close of business on the purchase date, as described below, whether the holder elects:

	•	to withdraw the purchase notice as to some or all of the notes to which it relates; or
	•	to receive cash in respect of the entire purchase price for all notes or portions of notes subject to such purchase notice.

26

---

 

      If the purchase price for the notes subject to the purchase notice is ultimately to be paid to a holder entirely in cash because we have not satisfied one or more of the conditions to payment of the purchase price in common stock prior to the close of business on the purchase date, a holder shall be deemed to have elected to receive cash in respect of the entire purchase price for all such notes unless such holder has properly notified us of its election to withdraw the purchase notice. For a discussion of the tax treatment of a holder receiving cash instead of common stock, see “Certain United States Federal Income Tax Considerations — U.S. Holders — Sale, Exchange, Redemption and Other Disposition of Notes.”

      Any purchase notice may be withdrawn by the holder by a written notice of withdrawal delivered to the paying agent prior to the close of business on the business day prior to the purchase date.

      The notice of withdrawal shall state:

	•	the principal amount at maturity being withdrawn;
	•	the certificate numbers of the notes being withdrawn; and
	•	the principal amount at maturity, if any, of the notes that remain subject to the purchase notice.

      If we elect to pay the purchase price, in whole or in part, in shares of our common stock, the number of such shares we deliver shall be equal to the portion of the purchase price to be paid in common stock divided by the market price of a share of common stock.

      We will pay cash based on the market price for all fractional shares of common stock in the event we elect to deliver common stock in payment, in whole or in part, of the purchase price. See “Certain United States Federal Income Tax Considerations — U.S. Holders — Sale, Exchange, Redemption and Other Disposition of Notes.”

      The market price of our common stock shall be an amount equal to the average of the sale prices of our common stock for the five-trading-day period ending on the third business day prior to the applicable purchase date, or, if such business day is not a trading day, then on the last trading day prior to such business day, appropriately adjusted to take into account any occurrence that would result in an adjustment of the conversion rate with respect to the common stock. See “— Conversion Rights” above for a description of the manner in which the sale price of our common stock is determined.

      Because the market price of our common stock is determined prior to the applicable purchase date, holders of notes bear the market risk with respect to the value of the common stock to be received from the date such market price is determined to such purchase date. We may pay the purchase price or any portion of the purchase price in common stock only if the information necessary to calculate the market price is published in a daily newspaper of national circulation.

      Upon determination of the actual number of shares of common stock in accordance with the foregoing provisions, we will promptly issue a press release and publish such information on our website.

      Our right to purchase notes, in whole or in part, with common stock is subject to our satisfying various conditions, including:

	•	giving timely notice of our election to purchase notes with common stock;
	•	the receipt by the trustee of an officers’ certificate and an opinion of counsel with respect to the issuance of common stock;
	•	listing the common stock on the Nasdaq National Market or listing on a national securities exchange;
	•	the registration of the common stock under the Securities Act and the Exchange Act, if required; and
	•	any necessary qualification or registration under applicable state securities law or the availability of an exemption from such qualification and registration.

      If such conditions are not satisfied with respect to a holder prior to the close of business on the purchase date, we will pay the purchase price of the notes of the holder entirely in cash. See “Certain United States

27

---

 

      In connection with any purchase offer, we will:

	•	comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable; and
	•	file Schedule TO or any other required schedule under the Exchange Act.

      Payment of the purchase price for a note for which a purchase notice has been delivered and not validly withdrawn is conditioned upon delivery of the note, together with necessary endorsements, to the paying agent at any time after delivery of the purchase notice. Payment of the purchase price for the note will be made as soon as practicable following the later of the purchase date or the time of delivery of the note.

      If the paying agent holds money or securities sufficient to pay the purchase price of the note on the business day following the purchase date in accordance with the terms of the indenture, then, immediately after the purchase date, the note will cease to be outstanding and cash interest or original issue discount on such note will cease to accrue, whether or not the note is delivered to the paying agent. Thereafter, all other rights of the holder shall terminate, other than the right to receive the purchase price upon delivery of the note.

      No notes may be purchased for cash at the option of holders if there has occurred and is continuing an event of default with respect to the notes, other than a default in the payment of the purchase price with respect to such notes.

Change of Control Permits Purchase of Notes by Mesa Air at the Option of the Holder

      In the event of a change of control, each holder will have the right, at the holder’s option, subject to the terms and conditions of the indenture, to require us to purchase for cash all or any portion of the holder’s notes. However, the principal amount at maturity submitted for purchase by a holder must be $1,000 or an integral multiple of $1,000.

      We will be required to purchase the notes as of a date no later than 30 business days after the occurrence of such change of control at a cash price equal to the sum of the issue price plus accrued original issue discount or accrued cash interest, if any, on such note to such date of purchase.

      If prior to such date of purchase upon a change of control the notes have been converted to semiannual coupon notes following the occurrence of a tax event, we will be required to purchase the notes at a cash price equal to the restated principal amount plus accrued and unpaid interest from the date of the conversion to such date of purchase.

      Within 15 days after the occurrence of a change of control, we are obligated to mail to the trustee and to all holders of notes at their addresses shown in the register of the registrar and to beneficial owners as required by applicable law a notice regarding the change of control, which notice shall state, among other things:

	•	the events causing a change of control;
	•	the date of such change of control;
	•	the last date on which the purchase right may be exercised;
	•	the change of control purchase price;
	•	the change of control purchase date;
	•	the name and address of the paying agent and the conversion agent;
	•	the conversion rate and any adjustments to the conversion rate resulting from such change of control;

28

---

 

	•	that notes with respect to which a change of control purchase notice is given by the holder may be converted only if the change of control purchase notice has been withdrawn in accordance with the terms of the indenture; and
	•	the procedures that holders must follow to exercise these rights.

      To exercise this right, the holder must deliver a written notice to the paying agent prior to the close of business on the business day prior to the change of control purchase date. The required purchase notice upon a change of control shall state:

	•	the certificate numbers of the notes to be delivered by the holder;
	•	the portion of the principal amount at maturity of notes to be purchased, which portion must be $1,000 or an integral multiple of $1,000; and
	•	that we are to purchase such notes pursuant to the applicable provisions of the notes.

      Any such change of control purchase notice may be withdrawn by the holder by a written notice of withdrawal delivered to the paying agent prior to the close of business on the business day prior to the change of control purchase date.

      The notice of withdrawal shall state:

	•	the principal amount at maturity being withdrawn;
	•	the certificate numbers of the notes being withdrawn; and
	•	the principal amount at maturity, if any, of the notes that remain subject to a change of control purchase notice.

      Payment of the change of control purchase price for a note for which a change of control purchase notice has been delivered and not validly withdrawn is conditioned upon delivery of the note, together with necessary endorsements, to the paying agent at any time after the delivery of such change of control purchase notice. Payment of this change of control purchase price for such note will be made promptly following the later of the change of control purchase date or the time of delivery of such note.

      If the paying agent holds money sufficient to pay the change of control purchase price of the note on the business day following the change of control purchase date in accordance with the terms of the indenture, then immediately after the change of control purchase date, cash interest or original issue discount on the note will cease to accrue, whether or not the note is delivered to the paying agent. Thereafter, all other rights of the holder shall terminate, other than the right to receive the change of control purchase price upon delivery of the note.

      Under the indenture, a “change of control” of Mesa Air is deemed to have occurred upon the occurrence of any of the following:

	•	the sale, lease, transfer, conveyance or other disposition (other than by way of merger or consolidation), in one or a series of related transactions, of all or substantially all of our and our subsidiaries’ assets, taken as a whole, to any person or group;
	•	the adoption of a plan relating to our liquidation or dissolution;
	•	the consummation of any transaction (including, without limitation, any merger or consolidation) the result of which is that any person or group becomes the beneficial owner, directly or indirectly, of more than 35% of the voting power of our outstanding voting stock; or
	•	the first day on which more than a majority of the members of our board of directors are not continuing directors.

29

---

 

      “Continuing directors” means any member of our board of directors who:

	•	was a member of our board of directors on the date of original issuance of the notes; or
	•	was nominated for election to our board of directors with the approval of, or whose election to our board of directors was ratified by, at least a majority of the continuing directors who were members of our board of directors at the time of such nomination or election.

      In connection with any purchase offer in the event of a change of control, we will:

	•	comply with the provisions of Rule 13e-4, Rule 14e-1 and any other tender offer rules under the Exchange Act which may then be applicable; and
	•	file Schedule TO or any other required schedule under the Exchange Act.

      The change of control purchase feature of the notes may, in certain circumstances, make more difficult or discourage a takeover of Mesa Air. The change of control purchase feature, however, is not the result of our knowledge of any specific effort:

	•	to accumulate shares of common stock;
	•	to obtain control of us by means of a merger, tender offer, solicitation or otherwise; or
	•	part of a plan by management to adopt a series of anti-takeover provisions.

      Instead, the change of control purchase feature is a standard term contained in other offerings of securities similar to the notes that have been marketed by the initial purchaser. The terms of the change of control purchase feature resulted from negotiations between the initial purchaser and us.

      We could, in the future, enter into certain transactions, including certain recapitalizations, that would not constitute a change of control with respect to the change of control purchase feature of the notes but that would increase the amount of our or our subsidiaries’ outstanding indebtedness.

      No notes may be purchased at the option of holders upon a change of control if there has occurred and is continuing an event of default with respect to the notes, other than a default in the payment of the change of control purchase price with respect to the notes.

Events of Default and Acceleration

      The following are events of default under the indenture:

	•	default in the payment of any principal amount (including accrued original issue discount and, if the notes have been converted to semiannual coupon notes following a tax event, the restated principal amount) at maturity, redemption price, purchase price, or change of control purchase price due with respect to the notes, when the same become due and payable;
	•	default in payment of any interest under the notes, which default continues for 30 days;
	•	our failure to comply with any of our other agreements in the notes or the indenture upon our receipt of notice of such default from the trustee or from holders of not less than 25% in aggregate principal amount at maturity of the notes, and our failure or such guarantor’s failure to cure (or obtain a waiver of) such default within 60 days after we receive such notice;
	•	default in the payment of principal when due or resulting in acceleration of other indebtedness of ours for borrowed money where the aggregate principal amount with respect to which the default or acceleration has occurred exceeds $10,000,000, and such acceleration has not been rescinded or annulled within a period of 10 days after written notice to us by the trustee or to us and the trustee by the holders of at least 25% in principal amount at maturity of the notes; or
	•	any guarantee ceases to be in full force and effect or is declared null and void or any guarantor denies that it has any further liability under any guarantee, or gives notice to such effect (other than by reason of the termination of the indenture or the release of any such guarantee in accordance with the

30

---

 

		indenture), and such condition shall have continued for a period of 30 days after written notice of such failure requiring the guarantor or us to remedy the same shall have been given to us by the trustee or to us and the trustee by the holders of 25% in aggregate principal amount at maturity of the notes outstanding; or
	•	certain events of bankruptcy, insolvency or reorganization affecting us.

      If an event of default shall have happened and be continuing, either the trustee or the holders of not less than 25% in aggregate principal amount at maturity of the notes then outstanding may declare the issue price of the notes plus the original issue discount on the notes accrued through the date of such declaration, and any accrued and unpaid cash interest (or, if the notes have been converted to semiannual coupon notes following a tax event, the restated principal amount, plus accrued interest) through the date of such declaration, to be immediately due and payable. In the case of certain events of bankruptcy or insolvency, the issue price of the notes plus the original issue discount accrued thereon, together with any accrued cash interest (or, if the notes have been converted to semiannual coupon notes following a tax event, the restated principal amount, plus accrued interest) through the occurrence of such event shall automatically become and be immediately due and payable.

Mergers and Sales of Assets

      The indenture provides that we may not consolidate with or merge into any person or convey, transfer or lease our properties and assets substantially as an entity to another person unless:

	•	the resulting, surviving or transferee person is organized and existing under the laws of the United States, any state thereof or the District of Columbia, and (if other than us) assumes all our obligations under the notes and the indenture;
	•	immediately after giving effect to the transaction no event of default has occurred and is continuing; and
	•	other conditions described in the indenture are met.

      Upon the assumption of our obligations by such corporation in such circumstances, subject to certain exceptions, we shall be discharged from all obligations under the notes and the indenture. Although such transactions are permitted under the indenture, certain of the foregoing transactions occurring could constitute a change of control of Mesa Air, permitting each holder to require us to purchase the notes of such holder as described above.

      The indenture also provides that a guarantor may not consolidate with or merge into any person or convey, transfer or lease its properties and assets substantially as an entity to another person unless the surviving person assumes the obligations of such guarantor and the surviving person is a corporation organized and existing under the laws of the United States, any state thereof or the District of Columbia, except if all of the assets or all of the common stock of such guarantor is sold to a non-affiliate of Mesa Air, in which case the guarantee is released.

Optional Conversion to Semiannual Coupon Notes upon Tax Event

      From and after the date of the occurrence of a tax event, we shall have the option to elect to have interest in lieu of future accrued original issue discount or cash interest accrue at 3.625% per year on a principal amount per note equal to the sum of the issue price and accrued original issue discount on such note on the date of the tax event or the date on which we exercise such option, whichever is later.

      Such interest shall accrue from the option exercise date, and shall be payable semiannually on the interest payment dates of February 10 and August 10 of each year to holders of record at the close of business on February 1 or August 1 immediately preceding the interest payment date. Interest will be computed on the basis of a 360-day year comprised of twelve 30-day months. Interest will accrue from the most recent date to which interest, if applicable, has been paid or provided for or, if no interest is payable or has been paid or provided for, from the option exercise date. In the event that we exercise our option to pay interest in lieu of

31

      A “tax event” means that we shall have received an opinion from independent tax counsel experienced in such matters to the effect that, on or after the date of this prospectus, as a result of:

	•	any amendment to, or change (including any announced prospective change) in, the laws (or any regulations thereunder) of the United States or any political subdivision or taxing authority thereof or therein; or
	•	any amendment to, or change in, an interpretation or application of such laws or regulations by any legislative body, court, governmental agency or regulatory authority,

in each case which amendment or change is enacted, promulgated, issued or announced or which interpretation is issued or announced or which action is taken, on or after the date of this prospectus, there is more than an insubstantial risk that accrued original issue discount payable on the notes either:

	•	would not be deductible on a current accrual basis; or
	•	would not be deductible under any other method,

in either case in whole or in part, by us (by reason of deferral, disallowance, or otherwise) for United States federal income tax purposes.

      The Clinton administration previously proposed to change the tax law to defer the deduction of original issue discount on convertible debt instruments until the issuer pays the interest. Congress did not enact those proposed changes. It is not certain what the views of the Bush administration are on this issue and we cannot assure you that the same or a similar proposal will not be proposed and enacted.

      If a similar proposal were ever enacted and made applicable to the notes in a manner that would limit our ability to either

	•	deduct the interest, including the accrued original issue discount, payable on the notes on a current accrual basis; or
	•	deduct the interest, including accrued original issue discount, payable on the notes under any other method for United States federal income tax purposes,

such enactment would result in a tax event and the terms of the notes would be subject to modification at our option as described above.

      The modification of the terms of notes by us upon a tax event as described above could possibly alter the timing of income recognition by holders of the notes with respect to the semiannual payments of interest due on the notes after the date on which we exercise our option to pay interest in lieu of accrued original issue discount or accrued interest, if any, on the notes.

Modification

      The trustee and we may modify or amend the indenture or the notes with the consent of the holders of not less than a majority in aggregate principal amount at maturity of the notes then outstanding. However, the consent of the holders of each outstanding note would be required to:

	•	alter the manner of calculation or rate of accrual of original issue discount or interest on any note or change the time of payment;
	•	make any note payable in money or securities other than that stated in the note;
	•	change the stated maturity of any note;
	•	reduce the principal amount at maturity, restated principal amount, issue price, accrued original issue discount, redemption price, purchase price or change of control purchase price with respect to any note;

	•	make any change that adversely affects the rights of a holder to convert any note;
	•	make any change that adversely affects the right to require us to purchase a note;
	•	impair the right to institute suit for the enforcement of any payment with respect to, or conversion of, the notes;
	•	change the provisions in the indenture that relate to modifying or amending the indenture; and
	•	release any guarantor from any of its obligations under its guarantee other than in accordance with the terms of the indenture.

      Without the consent of any holder of notes, the trustee and we may enter into supplemental indentures for any of the following purposes:

	•	to evidence a successor to us and the assumption by that successor of our obligations under the indenture and the notes;
	•	to add to our covenants for the benefit of the holders of the notes or to surrender any right or power conferred upon us;
	•	to secure our obligations in respect of the notes;
	•	to cure any ambiguity or inconsistency in the indenture; or
	•	to make any change that does not adversely affect the rights of any holder of the notes.

      The holders of a majority in principal amount at maturity of the outstanding notes may, on behalf of all the holders of all notes:

	•	waive compliance by us with restrictive provisions of the indenture, as detailed in the indenture; and
	•	waive any past default under the indenture and its consequences, except a default in the payment of the principal amount at maturity, issue price, accrued and unpaid interest, accrued original issue discount, redemption price, purchase price or change of control purchase price or obligation to deliver common stock upon conversion with respect to any note or in respect of any provision which under the indenture cannot be modified or amended without the consent of the holder of each outstanding note affected.

Discharge of the Indenture

      We may satisfy and discharge our obligations under the indenture by delivering to the trustee for cancellation all outstanding notes or by depositing with the trustee, the paying agent or the conversion agent, if applicable, after the notes have become due and payable, whether at stated maturity or any redemption date, or any purchase date, or a change of control purchase date, or upon conversion or otherwise, cash or shares of common stock (as applicable under the terms of the indenture) sufficient to pay all of the outstanding notes and paying all other sums payable under the indenture.

Calculations in Respect of Notes

      We are responsible for making all calculations called for under the notes. These calculations include, but are not limited to, determination of the market prices of our common stock. We are required to make all these calculations in good faith and, absent manifest error, our calculations are final and binding on holders of notes. We are required to provide a schedule of our calculations to the trustee, and the trustee is entitled to rely upon the accuracy of our calculations without independent verification.

Limitations of Claims in Bankruptcy

      If a bankruptcy proceeding is commenced in respect of Mesa Air or any guarantor, the claim of a holder of a note is, under Title 11 of the United States Code, limited to the issue price of the note plus that portion of the original issue discount, together with any cash interest, that has accrued from the date of issue to the commencement of the proceeding.

Governing Law

      The indenture and the notes and guarantees are governed by, and construed in accordance with, the law of the State of New York.

Information Concerning the Trustee

      U.S. Bank National Association is the trustee, registrar, paying agent and conversion agent under the indenture for the notes.

Book-Entry System

      The notes are issued in the form of global securities held in book-entry form. DTC or its nominee is the sole registered holder of the notes for all purposes under the indenture. Owners of beneficial interests in the notes represented by the global securities will hold their interests pursuant to the procedures and practices of DTC. As a result, beneficial interests in any such securities are shown on, and may only be transferred through, records maintained by DTC and its direct and indirect participants and any such interest may not be exchanged for certificated securities, except in limited circumstances. Owners of beneficial interests must exercise any rights in respect of their interests, including any right to convert or require purchase of their interests in the notes, in accordance with the procedures and practices of DTC. Beneficial owners are not holders and will not be entitled to any rights under the global securities or the indenture. Mesa Air and the trustee, and any of their respective agents, may treat DTC as the sole holder and registered owner of the global securities.

Exchange of Global Securities

      Notes represented by a global security are exchangeable for certificated securities with the same terms only if:

	•	DTC is unwilling or unable to continue as depositary or if DTC ceases to be a clearing agency registered under the Exchange Act and a successor depositary is not appointed by us within 90 days;
	•	we decide to discontinue use of the system of book-entry transfer through DTC (or any successor depositary); or
	•	a default under the indenture occurs and is continuing.

      DTC has advised us as follows: DTC is a limited-purpose trust company organized under the New York Banking Law, a “banking organization” within the meaning of the New York Uniform Commercial Code, and a “clearing agency” registered pursuant to the provisions of Section 17A of the Exchange Act. DTC facilitates the settlement of transactions among its participants through electronic computerized book-entry changes in participants’ accounts, eliminating the need for physical movement of securities certificates. DTC’s participants include securities brokers and dealers, including the underwriters, banks, trust companies, clearing corporations and other organizations, some of whom and/or their representatives, own DTC. Access to DTC’s book-entry system is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a participant, either directly or indirectly.

Registration Rights

      We and the guarantors entered into a registration rights agreement with the initial purchaser of the notes pursuant to which we, at our expense, for the benefit of the holders, agreed to file with the SEC a shelf registration statement covering resale of the notes and the shares of common stock issued upon conversion of the notes within 90 days after the first date of original issuance of the notes. We agreed to use our reasonable efforts to cause the shelf registration statement to become effective within 180 days of such first date of original issuance, and to keep a shelf registration statement effective until the earlier of (i) the sale pursuant to a shelf registration statement of all the securities registered thereunder and (ii) the expiration of the holding

34

---

 

      We will be permitted to suspend the use of a prospectus that is part of a shelf registration statement under certain circumstances relating to corporate developments, public filings with the SEC and similar events for a period not to exceed 45 days in any three-month period and not to exceed an aggregate of 120 days in any 12-month period. We will agree to pay predetermined liquidated damages as described herein (“liquidated damages”) to holders of the notes and holders of shares of common stock issuable upon conversion of the notes if a shelf registration statement is not timely filed or made effective or if the prospectus is unavailable for the periods in excess of those permitted above. Such liquidated damages shall accrue until such failure to file or become effective or unavailability is cured, (i) in respect of any notes, at a rate per year equal to 0.25% for the first 90 day period after the occurrence of such event and 0.50% thereafter of the applicable principal amount (as defined below) thereof and, (ii) in respect of any shares of common stock issued upon conversion at a rate per year equal to 0.25% for the first 90 day period and 0.50% thereafter of the then applicable conversion price (as defined below). So long as the failure to file or become effective or unavailability continues, we will pay liquidated damages in cash on February 10 and August 10 of each year to the holders of record of the notes or shares of common stock on the immediately preceding February 1 or August 1. When such registration default is cured, accrued and unpaid liquidated damages will be paid in cash to the record holder as of the date of such cure.

      A holder who sells notes and shares of common stock issued upon conversion of the notes pursuant to the shelf registration statement generally will be required to be named as a selling securityholder in the related prospectus, deliver a prospectus to purchasers and be bound by certain provisions of the registration rights agreement that are applicable to such holder, including certain indemnification provisions. We will pay all expenses of a shelf registration statement, provide to each registered holder copies of such prospectus, notify each registered holder when the shelf registration statement has become effective and take certain other actions as are required to permit, subject to the foregoing, unrestricted resales of the notes and the shares of common stock issued upon conversion of the notes.

      The term “applicable principal amount” means, as of any date of determination, with respect to each $1,000 principal amount at maturity of notes, the sum of the initial issue price of such notes plus accrued original issue discount with respect to such notes through such date of determination or, if no notes are then outstanding, such sum calculated as if such notes were then outstanding.

      The term “applicable conversion price” means, as of any date of determination, the applicable principal amount per $1,000 principal amount at maturity of notes as of such date of determination divided by the conversion rate in effect as of such date of determination or, if no notes are then outstanding, the conversion rate that would be in effect were notes then outstanding.

      We agreed in the registration rights agreement to give notice to all holders of the filing and effectiveness of a shelf registration statement by release made to Reuters Economic Services and Bloomberg Business News or other reasonable means of distribution.

      The summary herein of certain provisions of the registration rights agreement is subject to, and is qualified in its entirety by reference to, all the provisions of the registration rights agreement, a copy of which is available upon request to Mesa Air.

DESCRIPTION OF CAPITAL STOCK

      Our authorized capital stock consists of 75,000,000 shares of common stock, no par value per share, and 2,000,000 shares of preferred stock, no par value per share.

Common Stock

      This prospectus covers, and the registration statement of which it is a part, registers the 6,920,415 shares of common stock issuable upon conversion of the notes.

      The shares issued upon the conversion of the notes are subject to specified anti-dilution provisions set forth in the indenture relating to the notes.

      As of May 11, 2004, there were 31,703,874 shares of common stock outstanding and held of record by 1,181 stockholders. The holders of common stock are entitled to one vote for each share held of record on all matters submitted to a vote of the stockholders. Cumulative voting for the election of directors is not permitted subject to preferences that may be applicable to any outstanding shares of preferred stock, the holders of common stock are entitled to receive ratably those dividends as may be declared by the board of directors out of funds legally available therefor. In the event of a liquidation, our dissolution or winding up, holders of the common stock are entitled to share ratably in all assets remaining after payment of liabilities and the liquidation preferences of any outstanding shares of preferred stock. Holders of common stock have no preemptive rights and no right to convert their common stock into any other securities. There are no redemption or sinking fund provisions applicable to the common stock. All outstanding shares of common stock are, and all shares of common stock to be outstanding upon completion of the offering will be, fully-paid and nonassessable. Our common stock is listed on the Nasdaq National Market under the symbol “MESA.”

Preferred Stock

      There are, and upon completion of the offering, there will be, no shares of preferred stock outstanding. The board of directors has the authority, without further action by the stockholders, to issue up to 2,000,000 shares of preferred stock, no par value per share, in one or more series and to fix the powers, preferences, privileges, rights and qualifications, limitations or restrictions thereof, including dividend rights, conversion rights, voting rights, terms of redemption, liquidation preferences, sinking fund terms and the number of shares constituting any series or the designation of the series, without any further vote or action by stockholders. We believe that the board of directors’ authority to set the terms of, and our ability to issue, preferred stock will provide flexibility in connection with possible financing transactions in the future. The issuance of preferred stock, however, could adversely affect the voting power of holders of common stock, and the likelihood that the holders will receive dividend payments and payments upon liquidation and could have the effect of delaying, deferring or preventing a change of control in us. We have no present plan to issue any shares of preferred stock.

Anti-Takeover Provisions of Nevada Law

      We are subject to the provisions of the Nevada private corporation law, which are anti-takeover provisions. In general, the provisions of Sections 78.411-444 prohibit a publicly held Nevada corporation from engaging in a “business combination” with an “interested stockholder” for a period of three years following the date the person became an interested stockholder, unless (with certain exceptions) the “business combination” or the transaction in which the person became an interested stockholder is approved in a prescribed manner. Generally, a “business combination” includes a merger, asset or stock sale, or other transaction resulting in a financial benefit to the interested stockholder. Generally, an “interested stockholder” is a person who, together with affiliates and associates, owns or within three years prior to the determination of interested stockholder status, did own, 10% or more of a corporation’s voting stock. The existence of this provision may have an anti-takeover effect with respect to transactions not approved in advance by the board of directors, including discouraging attempts that might result in a premium over the market price for the shares of common stock held by stockholders.

Registration Rights

      In February 2002, we reached an agreement with Raytheon Aircraft Credit Company to reduce the operating costs of its Beechcraft 1900D fleet. In consideration for Raytheon’s financial accommodations under that agreement, we granted Raytheon an option to purchase up to 233,068 warrants over a three-year period pursuant to a warrant purchase agreement. Each warrant entitles the holder to purchase one share of common stock. Pursuant to the warrant purchase agreement, Raytheon has the right to cause us to register shares of common stock under the Securities Act. Under the terms of the warrant purchase agreement, Raytheon has the right so long as it holds any warrants or warrant shares, to require us to file a registration statement under the Securities Act covering all of the warrant shares held by them and to request that such registration remain effective until October 15, 2006. In addition, the warrant purchase agreement provides for “piggyback” registration rights with respect to the warrant shares whenever we file a registration statement on a registration form that can be used to register the warrant shares held by Raytheon. Raytheon must pay its pro rata share of the registration expenses and reasonable maintenance cost incurred in connection with these registrations. We filed a registration statement with the SEC in 2003 to register the resale of the Company’s senior convertible notes due 2023 and the shares of common stock issuable upon conversion of such notes. Raytheon exercised its piggyback registration rights in connection with this SEC filing.

      We also granted registration rights to the holders of our senior convertible notes due 2023. The terms of such registration rights are substantially the same as the registration rights described under “Description of Notes — Registration Rights” with respect to the senior convertible notes due 2024.

Limitations on Liability and Indemnification of Officers and Directors

      Our articles of incorporation provide that, to the fullest extent permitted by Nevada law, none of our directors will be personally liable to us or to our stockholders for monetary damages for breach of fiduciary duties. The provision effectively eliminates our rights and the rights of our stockholders to recover monetary damages against a director for breach of fiduciary duty as a director, including breaches from grossly negligent conduct. This provision does not, however, exonerate directors from liability under federal securities laws or for (1) breach of a director’s duty of loyalty to us or to our stockholders, (2) acts or omissions not in good faith or that involve intentional misconduct or knowing violation of law, (3) specified willful or negligent acts relating to the payment of dividends or the repurchase or redemption of securities or (4) any transaction from which a director has derived an improper personal benefit. Our bylaws provide for indemnification of our officers and directors to the fullest extent permitted by applicable law. We also have entered into separate indemnification agreements with each of our directors and executive officers that impose contractual indemnification obligations on the Company with respect to specified claims made against such officers and directors.

Transfer Agent and Registrar

      Computershare Trust Company is the transfer agent and registrar for our common stock.

MATERIAL UNITED STATES FEDERAL INCOME TAX CONSIDERATIONS

      The following summary discusses certain material U.S. federal income tax (and in the case of non-U.S. holders, as defined below, certain U.S. federal estate tax) consequences relating to the purchase, ownership and disposition of the notes and the shares of common stock into which the notes may be converted. Except where noted, this summary deals only with notes and shares of common stock held as capital assets and is applicable only to initial individual purchasers of notes who purchased the notes for an amount of cash equal to the initial offering price of such notes. Additionally, this summary does not deal with special situations, such as:

	•	tax consequences to holders who may be subject to special tax treatment, such as dealers in securities or currencies, banks, financial institutions, insurance companies, partnerships, tax- exempt entities and traders in securities that elect to use a mark-to-market method of accounting for their securities holdings;
	•	tax consequences to persons holding notes or common stock as part of a hedging, integrated, constructive sale or conversion transaction or a straddle;
	•	tax consequences to U.S. holders (as defined below) whose “functional currency” is not the U.S. dollar;
	•	alternative minimum tax consequences, if any; or
	•	any state, local or foreign tax consequences.

      The discussion below is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), and Treasury regulations, rulings and judicial decisions as of the date hereof. Those authorities may be changed, perhaps retroactively, so as to result in U.S. federal income tax consequences different from those discussed below. There can be no assurance that the Internal Revenue Service (the “IRS”) will not challenge one or more of the tax consequences discussed herein. If a partnership holds our notes or common stock, the tax treatment of a partner in the partnership will generally depend upon the status of the partner and the activities of the partnership. If you are a partner of a partnership holding our notes or common stock, you should consult your tax adviser. Whether a note is treated as debt (and not equity) for U.S. federal income tax purposes is an inherently factual question and no single factor is determinative. We are treating the notes as indebtedness for U.S. federal income tax purposes and the following discussion assumes that such treatment will be respected.

      IF YOU ARE CONSIDERING THE PURCHASE OF NOTES, YOU SHOULD CONSULT YOUR OWN TAX ADVISERS CONCERNING THE U.S. FEDERAL INCOME TAX CONSEQUENCES TO YOU AND ANY CONSEQUENCES ARISING UNDER THE LAWS OF ANY OTHER TAXING JURISDICTION.

U.S. Holders

      The following is a summary of certain material U.S. federal income tax consequences that will apply to you if you are a U.S. holder. A “U.S. holder” means a beneficial owner of a note or common stock that is:

	•	a citizen or resident alien individual of the United States;
	•	a corporation (or any entity treated as a corporation for U.S. federal income tax purposes) created or organized in or under the laws of the United States or any political subdivision of the United States;
	•	an estate the income of which is subject to U.S. federal income taxation regardless of its source; or
	•	a trust if it (1) is subject to the primary supervision of a court within the United States and one or more U.S. persons have the authority to control all substantial decisions of the trust or (2) has a valid election in effect under applicable U.S. Treasury regulations to be treated as a U.S. person.

	Original Issue Discount

      The notes have original issue discount (“OID”) for U.S. federal income tax purposes, and accordingly, U.S. holders are subject to special rules relating to the accrual of income for such purposes. U.S. holders generally must include OID in gross income for U.S. federal income tax purposes on an annual basis under a constant yield accrual method regardless of their regular method of tax accounting. As a result, U.S. holders will be required to include OID in income in advance of the receipt of cash attributable to such income.

      The notes are treated as issued with OID equal to the excess of a note’s “stated redemption price at maturity” over its “issue price.” The stated redemption price at maturity of a note will include all payments of principal and stated interest on the note. The notes provide for payment of interest in cash through February 10, 2009. Such interest will be included in the stated redemption price at maturity and taxed as part of OID and will not be again included separately in gross income of U.S. holders when accrued or paid. The issue price is the first price at which a substantial amount of notes is sold for money (excluding sales to bond houses, brokers or similar persons or organizations acting as underwriters, placement agents or wholesalers). The amount of OID includible in income by an initial U.S. holder is the sum of the “daily portions” of OID with respect to the note for each day during the taxable year or portion thereof in which such U.S. holder holds such note (“accrued OID”). A daily portion is determined by allocating to each day in any “accrual period” a pro rata portion of the OID that accrued in such period. The “accrual period” of a note may be of any length and may vary in length over the term of the note, provided that each accrual period is no longer than one year and each scheduled payment of principal or interest occurs either on the first or last day of an accrual period. The amount of OID that accrues with respect to any accrual period is the product of the note’s adjusted issue price at the beginning of such accrual period and its yield to maturity, determined on the basis of compounding at the close of each accrual period and properly adjusted for the length of such period. The “adjusted issue price” of a note at the start of any accrual period is equal to its issue price, increased by the accrued OID for each prior accrual period and reduced by any payments of interest and principal made on such note.

      We may be required to make payments of liquidated damages if we do not file or cause to be declared effective a registration statement, as described under “— Description of the Notes — Registration Rights.” We intend to take the position for U.S. federal income tax purposes that any payments of liquidated damages should be taxable to you as additional ordinary income when received or accrued, in accordance with your method of tax accounting. This position is based in part on the assumption that as of the date of issuance of the notes, the possibility that liquidated damages will have to be paid is a “remote” or “incidental” contingency within the meaning of applicable U.S. Treasury regulations. Our determination that such possibility is a remote or incidental contingency is binding on you, unless you explicitly disclose that you are taking a different position to the IRS on your tax return for the year during which you acquire the note. However, the IRS may take a contrary position from that described above, which could affect the timing and character of both your income from the notes and our deduction with respect to the payments of liquidated damages.

      If we do fail to file or cause to be declared effective a registration statement, you should consult your tax advisers concerning the appropriate tax treatment of the payment of liquidated damages with respect to the notes.

	Constructive Dividend

      The conversion price of the notes will be adjusted in certain circumstances. Under section 305(c) of the Code, adjustments (or failures to make adjustments) that have the effect of increasing your proportionate interest in our assets or earnings may in some circumstances result in a deemed distribution to you. Any deemed distributions will be taxable as a dividend, return of capital, or capital gain in accordance with the earnings and profits rules under the Code.

39

---

 

	Sale, Exchange, Redemption and other Disposition of Notes

      Except as provided below under “— Conversion of Notes into Common Stock,” you will generally recognize gain or loss upon the sale, exchange, redemption or other disposition of a note equal to the difference between the amount realized upon the sale, exchange, redemption or other disposition and your adjusted tax basis in the note, which will be equal to the amount paid for the note, increased by the amount of OID previously included in income (including in the tax year of disposition) and decreased by the amount of payments of interest and principal. Any gain or loss recognized on a disposition of the note will be capital gain or loss. If you are an individual and have held the note for more than one year, such capital gain will be subject to tax at a maximum rate of 15% (through December 31, 2008, after which time it reverts to a maximum rate of 20%). Your ability to deduct capital losses may be limited.

	Conversion of Notes into Common Stock

      You will not recognize any income, gain or loss on the conversion of your notes into common stock except to the extent of cash received in lieu of a fractional share of common stock. You will be required to include in gross income daily portions of the OID not previously included in gross income with respect to the notes, up to the date of conversion. Cash received in lieu of a fractional share of common stock generally should be treated as a payment in exchange for such fractional share. The amount of gain or loss on the deemed sale of such fractional share will be equal to the difference between the amount of cash you receive in respect of such fractional share, and the portion of your adjusted tax basis in the note that is allocable to the fractional share. The tax basis of the common stock received upon a conversion will equal the allocable portion of the adjusted tax basis of the note that was converted into common stock. Your holding period for common stock will include the period during which you held the notes. To the extent any common stock issued upon a conversion is allocable to accrued OID, the holding period for such common stock may commence on the day following the date of delivery of common stock, although there is no authority precisely on point.

	Dividends on Common Stock

      If, after you convert a note into common stock, we make a distribution of cash or other property (other than certain pro rata distributions of our common stock) in respect of that stock, the distribution will be treated as a dividend, taxable to you at a maximum rate of 15% (through December 31, 2008 after which time it reverts to being taxable at ordinary income rates), to the extent it is paid from our current and accumulated earnings and profits. If the distribution exceeds our current or accumulated earnings and profits, the excess will be treated first as a tax-free return of your investment, up to your basis in such common stock. Any remaining excess will be treated as capital gain. If you are a corporation, you may be able to claim a deduction for a portion of any distribution received that is considered a dividend.

	Sale or Other Disposition of Common Stock

      You will generally recognize capital gain or loss on a sale or other disposition of common stock. Your gain or loss will equal the difference between the proceeds you received and your adjusted tax basis in the stock. The proceeds received will include the amount of any cash and the fair market value of any other property received for the stock. If you are an individual and have held the stock for more than one year, such capital gain will be subject to tax at a maximum rate of 15% (through December 31, 2008, after which time it reverts to a maximum rate of 20%). Your ability to deduct capital losses may be limited.

	Exercise of the Optional Redemption or Repurchase Right

      If a U.S. holder requires us to repurchase a note on a repurchase date and we issue shares of our common stock in full satisfaction of the repurchase price, the exchange of a note for shares of our common stock should be treated in the same manner as a conversion.

40

---

 

      If a U.S. holder requires us to repurchase a note on a repurchase date and if we deliver a combination of cash and shares of our common stock in payment of the repurchase price, then, in general:

	•	a U.S. holder should recognize gain (but not loss) to the extent that the cash and the value of the shares exceed its adjusted tax basis in the note, but in no event should the amount of recognized gain exceed the amount of cash received;
	•	a U.S. holder will be required to include in gross income daily portions of the OID up to the date of conversion;
	•	a U.S. holder’s basis in the shares received should be the same as its basis in the note repurchased by us (exclusive of any basis allocable to a fractional share), decreased by the amount of cash received (other than cash received in lieu of a fractional share), and increased by the amount of gain, if any, recognized by such holder (other than gain with respect to a fractional share); and
	•	the holding period of the shares received in the exchange should include the holding period for the note that was repurchased, except that the holding period of shares attributable to accrued OID may commence on the day following the date of delivery of common stock, although there is no authority precisely on point.

      If we elect to exercise our option to purchase a note or if a U.S. holder requires us to repurchase a note on a repurchase date and if, in either event, we deliver to a holder cash in full satisfaction of the repurchase price, the repurchase will be treated the same as a sale of the note, as described above under “— Sale, Exchange, Redemption and other Disposition of the Notes.”

Non-U.S. Holders

      The following is a summary of certain material U.S. federal tax consequences that will apply to you if you are a non-U.S. holder. The term “non-U.S. holder” means a beneficial owner of a note or common stock that is an individual, corporation, trust or estate that is not a U.S. holder. Special rules may apply to certain non-U.S. holders such as “controlled foreign corporations”, “passive foreign investment companies”, “foreign personal holding companies”, persons eligible for benefits under income tax conventions to which the United States is a party and certain U.S. expatriates. Non-U.S. holders should consult their own tax advisers to determine the U.S. federal, state, local and other tax consequences that may be relevant to them.

	Payment of Interest

      The 30% U.S. federal withholding tax will not apply to any payment to you of interest on a note provided that:

	•	you do not actually or constructively own 10% or more of the total combined voting power of all classes of our stock that are entitled to vote within the meaning of session 871(h)(3) of the Code;
	•	you are not a “controlled foreign corporation” that is related to us within the meaning of section 864(d)(4) of the Code;
	•	you are not a bank whose receipt of interest on a note is described in section 881(c)(3)(A) of the Code; and
	•	you provide your name and address, and certify, under penalties of perjury, that you are not a U.S. person (which certification may be made on an IRS Form W-8BEN (or successor form)) or (b) you hold your notes through certain foreign intermediaries, and you and the foreign intermediary satisfy the certification requirements of applicable U.S. Treasury regulations.

      Special certification rules apply to non-U.S. holders that are pass-through entities rather than corporations or individuals.

      If you cannot satisfy the requirements described above, payments of interest will be subject to the 30% U.S. federal withholding tax, unless you provide us with a properly executed (1) IRS Form W-8BEN (or

41

      Absent further relevant guidance from the IRS, we intend to treat payments of liquidated damages made to non-U.S. holders as subject to U.S. withholding tax. Therefore, we intend to withhold on such payments at a rate of 30% unless we receive an IRS Form W-8BEN or an IRS Form W-8ECI from the non-U.S. holder claiming, respectively, that such payments are subject to reduction or elimination of withholding under an applicable treaty or that such payments are effectively connected with the conduct of a U.S. trade or business. A non-U.S. holder that is subject to the withholding tax should consult its own tax advisers as to whether it can obtain a refund for all or a portion of the withholding tax on the grounds that the liquidated damages qualify for the exemption applicable to interest (described above) within the meaning of the Code or some other grounds.

	Conversion of the Notes

      A non-U.S. holder generally will not recognize any income, gain or loss on converting a note into common stock. Any gain recognized as a result of the holder’s receipt of cash in lieu of a fractional share of stock would also generally not be subject to U.S. federal income tax. See “— Sale, Exchange or Redemption of Notes or Common Stock,” below.

	Dividends

      Any dividends paid to you with respect to our common stock (and any deemed dividends resulting from certain adjustments, or failure to make adjustments, to the number of shares of common stock to be issued on conversion, see “— U.S. Holders — Constructive Dividend” above) will be subject to withholding tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. However, dividends that are effectively connected with the conduct of a trade or business within the United States are not subject to the withholding tax, but instead generally are subject to U.S. federal income tax on a net income basis at applicable graduated individual or corporate rates. Certain certification and disclosure requirements must be complied with in order for effectively connected income to be exempt from withholding. Any such effectively connected dividends received by a foreign corporation may, under certain circumstances, be subject to an additional branch profits tax at a 30% rate or such lower rate as may be specified by an applicable income tax treaty. A non-U.S. holder of common stock who wishes to claim the benefit of an applicable treaty rate is required to satisfy applicable certification and other requirements. If you are eligible for a reduced rate of U.S. withholding tax pursuant to an income tax treaty, you may obtain a refund of any excess amounts withheld by filing an appropriate claim for refund with the IRS.

	Sale, Exchange or Redemption of Notes or Common Stock

      Any gain realized upon the sale, exchange, redemption or other disposition of a note or share of common stock generally will not be subject to U.S. federal income tax unless:

	•	that gain is effectively connected with the conduct of a trade or business in the United States by you,
	•	you are an individual who is present in the United States for 183 days or more in the taxable year of that disposition, and certain other conditions are met, or
	•	we are or have been a “U.S. real property holding corporation” for U.S. federal income tax purposes.

---

 

      A non-U.S. holder whose gain is described in the first bullet point above generally will be subject to U.S. federal income tax on the net gain derived from the sale at the applicable graduated rate(s). A corporate non-U.S. holder whose gain is described in the first bullet point above may also be subject to a branch profits tax at a 30% rate or a lower rate if an income tax treaty applies. An individual non-U.S. holder described in the second bullet point above will be subject to a flat 30% U.S. federal income tax on the gain derived from the sale, which may be offset by U.S. source capital losses, even though the holder is not considered a resident of the United States.

      We believe we are not and do not anticipate becoming a U.S. real property holding corporation for U.S. federal income tax purposes. However, there can be no assurances that we will not become a U.S. real property holding corporation in the future.

	U.S. Federal Estate Tax

      The U.S. federal estate tax will not apply to notes owned by you at the time of your death, provided that (1) you do not own 10% or more of the total combined voting power of all classes of our voting stock (within the meaning of the Code and the Treasury regulations) and (2) interest on the note would not have been, if received at the time of your death, effectively connected with your conduct of a trade or business in the United States. However, common stock held by you at the time of your death will be included in your gross estate for U.S. federal estate tax purposes unless an applicable estate tax treaty provides otherwise. Noteholders that are individuals should be aware that there have been recent amendments to the U.S. federal estate tax rules, and such persons should consult with their tax advisers before considering an investment in the notes.

Information Reporting and Backup Withholding

      If you are a U.S. holder, in general, information reporting requirements will apply to certain payments of principal and interest on the notes, dividends paid on the common stock, and the proceeds of sale of a note or share of common stock unless you are an exempt recipient (such as a corporation). Backup withholding tax will apply to such payments if you fail to provide your taxpayer identification number or certification of exempt status or fail to report in full dividend and interest income. The backup withholding rate currently is 28%.

      If you are a non-U.S. holder, in general, you will not be subject to backup withholding and information reporting with respect to payments that we make to you provided that we do not have actual knowledge or reason to know that you are a U.S. person and you have given us the statement described above under “— Non-U.S. Holders — Payment of Interest.” In addition, you will not be subject to backup withholding or information reporting with respect to the proceeds of the sale of a note or share of common stock within the United States or conducted through certain U.S.-related financial intermediaries, if the payor receives the statement described above and does not have actual knowledge or reason to know that you are a U.S. person, as defined under the Code, or you otherwise establish an exemption. However, we may be required to report annually to the IRS and to you the amount of, and the tax withheld, if any, with respect to, any interest or dividends paid to you, regardless of whether any tax was actually withheld. Copies of these information returns may also be made available under the provisions of a specific treaty or agreement to the tax authorities of the country in which the non-U.S. holder resides.

      Any amounts withheld under the backup withholding rules will be allowed as a refund or a credit against your U.S. federal income tax liability provided the required information is furnished timely to the IRS.

SELLING SECURITYHOLDERS

      The notes were originally issued by us in a private placement to initial purchaser Merrill Lynch Pierce, Fenner & Smith Incorporated and were simultaneously resold by the initial purchaser, in transactions exempt from the registration requirements of the Securities Act, to persons reasonably believed by the initial purchaser to be “qualified institutional buyers” (as defined in Rule 144A under the Securities Act). Each institution that purchased the notes from the initial purchaser and who has provided us with a questionnaire setting forth the information specified below. The selling securityholders, including their transferees, pledgees, donees and successors (collectively, a “selling securityholder”), may from time to time offer and sell pursuant to this prospectus or a supplement hereto any or all of the notes held by that selling securityholder and common stock underlying the notes.

      The following table sets forth information as of May 5, 2004, with respect to the selling securityholders and the principal amounts of notes beneficially owned by each selling securityholder that may be offered under this prospectus. This information is based on information provided by or on behalf of the selling securityholder pursuant to the questionnaires referred to above. No holder of the notes may sell the notes or shares without furnishing to us a questionnaire setting forth the information specified below. However, as of the date of this prospectus, not every holder has provided to us a questionnaire. Therefore, the heading “Other” in the “Name” column below represents the notes and shares held by holders who have not yet returned to us their questionnaire.

      The selling securityholder may offer all, some or none of the notes or common stock underlying the notes. In addition, the selling securityholder may have sold, transferred or otherwise disposed of all or a portion of their notes since the date on which they provided the information regarding their notes in transactions exempt form the registration requirements of the Securities Act. Based upon information provided by the selling securityholders, no selling securityholder beneficially owns one percent or more of our common stock assuming conversion of the selling securityholder’s notes, except as otherwise indicated in the table below. Based upon information provided by the selling securityholder, none of the selling security holders nor any of their affiliates, officers, directors or principal equity holders, has held any position or office or has had any material relationship with us within the past three years.

      Information concerning the selling securityholder may change from time to time and any changed information will be set forth in post-effective amendments to the registration statement of which this prospectus is apart. In addition, the conversion rate and, therefore, the number of shares of common stock issuable upon conversion of the notes, is subject to adjustment under certain circumstances. The information is based on information provided by or on behalf of the selling securityholders.

PLAN OF DISTRIBUTION

      The notes and the common stock are being registered to permit resale of theses securities by the selling securityholders from time to time after the date of this prospectus. We have agreed, among other things, to bear the expenses (other than underwriting discounts and selling commissions) incurred in connection with the registration and sale of the notes and the common stock covered by this prospectus. We will not receive any of the proceeds from the offering of the notes or the common stock by the selling securityholders.

      The selling securityholders and their successors, including their transferees, pledgees or donees or their successors, may sell the notes and the common stock into which the notes are convertible directly to purchasers or through underwriters, broker-dealers or agents, who may receive compensation in the form of discounts, concessions or commissions from the selling securityholders or the purchasers. These discounts, concessions or commissions as to any particular underwriter, broker-dealer or agent may be in excess of those customary in the types of transactions involved.

      The notes and the common stock into which the notes are convertible may be sold in one or more transactions at fixed prices, at prevailing market prices, at varying prices determined at the time of sale, or at negotiated prices. These sales may be effected in cross, block or other types of transactions:

	•	on any national securities exchange or U.S. inter-dealer system of a registered national securities association on which the notes or the common stock may be listed or quoted at the time of sale;
	•	in the over-the-counter market;
	•	in transactions otherwise than on these exchanges or in the over-the-counter market;
	•	through the writing of options, whether the options are listed on an options exchange or otherwise;
	•	through the settlement of short sales; or
	•	through any other legally available means.

      Our common stock is listed for trading on the Nasdaq National Market under the symbol “Mesa.”

      In connection with the sale of the notes and the common stock underlying the notes, the selling securityholders may enter into hedging transactions with broker-dealers or other financial institutions, which may in turn engage in short sales of the notes or the underlying common stock in the course of hedging the positions they assume. The selling securityholders may also sell the notes or the underlying common stock short and deliver these securities to close out their short positions, or loan or pledge the notes or the underlying common stock to broker-dealers that in turn may sell those securities.

      The aggregate proceeds to the selling securityholders from the sale of the notes or underlying common stock offered by them will be the purchase price of the notes or common stock less discounts and commissions, if any. Each of the selling securityholders reserves the right to accept and, together with their agents from time to time, to reject, in whole or in part, any proposed purchase of notes or underlying common stock to be made directly or through agents.

      In order to comply with the securities laws of some states, if applicable, the notes and underlying common stock may be sold in these jurisdictions only through registered or licensed brokers or dealers. In addition, in some states the notes and underlying common stock may not be sold unless they have been registered or qualified for sale or an exemption from registration or qualification requirements is available and is complied with.

      The selling securityholders and any underwriters, broker-dealers or agents that participate in the sale of the notes and underlying common stock may be “underwriters” within the meaning of Section 2(11) of the Securities Act. Any discounts, commissions, concessions or profit they earn on any resale of the shares may be underwriting discounts and commissions under the Securities Act. Selling securityholders who are “underwriters” within the meaning of Section 2(11) of the Securities Act will be subject to the prospectus delivery requirements of the Securities Act. The selling securityholders have acknowledged that they understand their

---

 

      In addition, any securities covered by this prospectus that qualify for sale pursuant to Rule 144 or Rule 144A of the Securities Act may be sold under Rule 144 or Rule 144A rather than pursuant to this prospectus.

      To the extent required, the specific notes or common stock to be sold, the names of the selling securityholders, the respective purchase prices and public offering prices, the names of any agent, dealer or underwriter, and any applicable commissions or discounts with respect to a particular offer will be set forth in an accompanying prospectus supplement or, if appropriate, a post-effective amendment to the registration statement of which this prospectus is a part.

      We entered into a registration rights agreement for the benefit of holders of the notes to register their notes and common stock under applicable federal and state securities laws under specific circumstances and at specific times. The registration rights agreement provides for cross-indemnification of the selling securityholders and us and their and our respective directors, officers and controlling persons against specified liabilities in connection with the offer and sale of the notes and the common stock, including liabilities under the Securities Act.

LEGAL MATTERS

      The validity of the notes and shares of common stock issuable upon conversion of the notes will be passed upon for us by Squire, Sanders & Dempsey L.L.P., 40 North Central Avenue, Suite 2700, Phoenix, Arizona 85004.

EXPERTS

      The financial statements incorporated in this prospectus by reference from our Annual Report on Amendment No. 2 of Form 10-K/A for the year ended September 30, 2003, have been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report, which is incorporated herein by reference (which report expresses an unqualified opinion and includes an explanatory paragraph relating to our significant code-share agreements and an explanatory paragraph relating to the restatement discussed in Note 23), and have been so incorporated in reliance upon the report of such firm given upon their authority as experts in accounting and auditing.

INFORMATION NOT REQUIRED IN PROSPECTUS

      The following table sets forth all expenses payable by us in connection with the offering of the notes being registered, other than discounts and commissions. The selling securityholders will not share any portion of these expenses.

Item 15.	Indemnification of Officers and Directors

      The Nevada General Corporation Law provides for indemnification of directors, officers, employees and agents, subject to certain limitations (Section 78.7502 Nevada General Corporation Law (“NGCL”)). Article Eighth of our Certificate of Incorporation provides that we may indemnify all persons whom it has the power to indemnify under Section 78.7502 of the NGCL, whether civil, criminal, administrative or investigative (including an action by or in the right of Mesa, by reason of the fact that he is or was serving as our director or officer (or is or was serving at our request in a similar capacity with another entity), shall be indemnified and held harmless by us to the fullest extent authorized by the NGCL. The right of indemnification includes the right to be paid by the Company the expenses incurred in defending any such action, suit or proceeding in advance of its final disposition. If required by us, however, such advancement of expenses shall be made only upon delivery of an undertaking by such director or officer to repay all amounts so advanced if it is ultimately determined that such director or officer is not entitled to be indemnified.

      As permitted by Section 78.747 of the NGCL, the Company’s Certificate of Incorporation contains provisions eliminating a director’s personal liability for monetary damages to us and our stockholders arising from a breach of a director’s fiduciary duty except for liability under Section 78.747 of the NGCL or liability for acts or omissions which involve intentional misconduct, fraud or a knowing violation of law or for the authorization of the unlawful payment of a dividend or other distribution on the Company’s capital stock, or the unlawful purchase of its capital stock.

Item 17.	Undertakings

      (a) The undersigned registrant hereby undertakes:

	(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

	(i) To include any prospectus required by Section 10(a)(3) of the Securities Act of 1933, as amended (the “Securities Act”);
	(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the forgoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high and of the estimated maximum offering range may be reflected in the form of prospectus filed with the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement;
	(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement;

	provided, however, that paragraphs (i) and (ii) above do not apply if the information required to be included in a post-effective amendment by those paragraphs is contained in periodic reports filed by Mesa Air Group, Inc. pursuant to Section 13 or Section 15(d) of the Securities Exchange Act of 1934, that are incorporated by reference in the registration statement.

	(2) That, for the purpose of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.
	(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

      (b) The undersigned registrant hereby undertakes, that, for purposes of determining any liability under the Securities Act of 1933, each filing of the registrant’s annual report pursuant to Section 13(a) or 15(e) of the Securities Exchange Act of 1934 (and, where applicable, each filing of an employee benefit plan’s annual report pursuant to Section 15(d) of the Securities Exchange Act of 1934) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered

II-2

      (c) Insofar as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by it is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

SIGNATURES

      Pursuant to the requirements of the Securities Act of 1933, the registrant certifies that it has reasonable grounds to believe that it meets all of the requirements for filing on Form S-3 and has duly caused this registration statement to be signed on its behalf by the undersigned, thereunto duly authorized, in the City of Phoenix, State of Arizona, on July 19, 2004.
