+ Based on a total of 26,331,075 Shares outstanding as of December 4, 2018,
as set forth in the Issuer's most recent Form 10-K dated December 12,2018.

Item 1.  Security and Issuer

The title of the class of equity security to which this statement on
Schedule 13D relates is the Common Stock, par value $0.0001 per share (the
"Common Stock") of Blue Bird Corporation, a Delaware corporation (the
"Issuer").

This Amendment No. 3 to Schedule 13D (this "Amendment No. 3") amends and
supplements the Schedule 13D filed on July 26, 2016 (the "Original Schedule
13D"), amended on August 2, 2016 ("Amendment No. 1"), and further amended
on October 29, 2018 ("Amendment No. 2").

All capitalized terms contained herein but not otherwise defined shall have the
meanings ascribed to such terms in the Original Schedule 13D.

Except as specifically amended by this Amendment No. 3, the Original Schedule
13D is unchanged.

The address of the Issuer's principal executive offices is
3920 Arkwright Road, Suite 200, Macon, Georgia 31210.


Item 3.  Source and Amount of Funds or Other Consideration

Item 3 is hereby amended by deleting Item 3 of the Original Schedule 13D in its
entirety and replacing it with the following:

The Shares to which this statement relates were acquired by the Reporting
Persons using the working capital of each Investment Vehicle as follows:

   The Spitfire Fund L.P.:   $9,031,917
   The Spitfire Qualified Fund L.P.:   $5,644,752
   Saunwin Domestic Equities Fund LLC:   $674,246
   ABA Stocks LLC:   $731,661

  The Investment Vehicles have invested an aggregate amount of approximately
  $16,082,576 in the Shares, including brokerage commissions.


Item 5.  Interest in Securities of the Issuer

Item 5 is hereby amended by deleting Item 5 of the Original Schedule 13D in
its entirety and replacing it with the following:

(a) The aggregate percentage of Shares reported owned by each person named
herein is based on 26,331,075 shares of Common Stock outstanding as of
December 4, 2018, which is the total number of shares of Common Stock
outstanding as reported in the Issuer's most recent Form 10-K, filed with
the Securities and Exchange Commission on December 12, 2018.

As of the close of business on the date hereof, Spitfire Capital, as the
investment adviser to the Investment Vehicles, may be deemed to beneficially
own the 1,271,178 Shares owned in the aggregate by the Investment Vehicles,
constituting approximately 4.83% of the shares of Common Stock outstanding.

during the past sixty days are set forth in Exhibit B.

to receive, or the power to direct the receipt of dividends from, or
proceeds from the sale of, the Shares.

(e) As of December 14, 2018, the Reporting Persons ceased to be the beneficial
owner of more than 5% of the Shares. As the Reporting Persons now own less
than 5% of the Shares, this will be the final Schedule 13D amendment filing
until such time, if any, as the Reporting Persons exceed the 5% ownership
threshold.


Item 6.  Contracts, Arrangements, Understandings or Relationships with Respect
to Securities of the Issuer

On December 17, 2018, the Reporting Persons entered into a Joint Filing
Agreement in which the Reporting Persons agreed to the joint filing on behalf
of each of them of statements on Schedule 13D with respect to securities of
the Issuer, to the extent required by applicable law.  A copy of this
agreement is attached hereto as Exhibit A and is incorporated herein by
reference.

Other than as described herein, there are no contracts, arrangements,
understandings or relationships among the Reporting Persons, or between the
Reporting Persons and any other person, with respect to the securities of
