         Douglas G. Voss ("Doug Voss") hereby amends his statement on Schedule
13D (the "Schedule 13D") originally filed on October 28, 1996, and amended on
April 28, 1997, August 31, 1998 and February 22, 2002, with respect to his
beneficial ownership of shares of common stock par value $.01 per share ("Common
Stock"), of Great Lakes Aviation, Ltd. ("Great Lakes"), an Iowa corporation.

         Item 1 of the Schedule 13D is hereby amended and restated as follows:

         Item 1: Security and Issuer

         The name of the Issuer is Great Lakes Aviation, Ltd. and the address of
its principal office is 1022 Airport Parkway, Cheyenne, Wyoming 82001. The title
of the class of equity security to which this statement relates is Common Stock.
Doug Voss beneficially owns 5,679,245 shares of Common Stock.

         Item 5 of the Schedule 13D is hereby amended and restated as follows:

         Item 5: Interest in Securities of the Issuer

         (a)   As of the date of this Schedule 13D, Doug Voss beneficially owned
5,679,245 shares of Common Stock constituting approximately 40.1% of outstanding
Common Stock of the Issuer.

         (b)   Doug Voss is the record owner of 2,648,245 shares of Common Stock
which includes 100,000 shares of Common Stock subject to currently exercisable
options. Doug Voss is also the sole shareholder of Iowa Great Lakes Flyers, Inc.
("Flyers") the record owner of 1,051,658 shares of Common Stock. Doug Voss'
ex-spouse, Gayle R. Brandt, has granted to him an Irrevocable Proxy to vote
1,979,342 shares of Common Stock of the Issuer owned of record by her and has
entered into a Buy-Sell Agreement with her with respect to all such shares. See
Item 6 of this Schedule 13D.

         (c)   On September 12, 2003, Flyers, of which Doug Voss is the sole
shareholder, acquired 172,413 shares of Common Stock in a private placement
transaction with Gayle R. Brandt, Doug Voss' ex-spouse, at a price of $0.29 per
share pursuant to the terms of the Buy-Sell Agreement entered into with her.

         (d)   Not applicable.

         (e)   Not applicable.

         Item 6 of the Schedule 13D is hereby amended and restated as follows:

         Item 6: Contracts, Arrangements, Understandings or Relationships With
                 Respect to Securities of the Issuer

         Doug Voss' ex-spouse, Gayle R. Brandt, who is the record owner of 14.1%
of the Common Stock of the Issuer, has granted to Doug Voss an Irrevocable Proxy
to vote all of her shares of Common Stock (the "Shares") until June 28, 2010.

                                       3



         Doug Voss and Gayle R. Brandt have entered into a Shareholder Buy-Sell
Agreement (the "Buy-Sell Agreement") with respect to the Shares. The term of the
Buy-Sell Agreement (the "Term") is until June 28, 2010 or until such time as
Gayle R. Brandt does not own any Shares or Great Lakes is dissolved or
liquidated. Pursuant to the Buy-Sell Agreement Gayle R. Brandt could not sell
any Shares until June 28, 1999 at which time she became able to sell 470,000
Shares and an additional 235,000 Shares in each year thereafter. Doug Voss,
however, has been granted a right of first refusal to purchase for the market
price any Shares which Gayle R. Brandt desires to so sell. The Buy-Sell
Agreement also provides Doug Voss the option to purchase any Shares at any time
during the Term for the market price of the Common Stock. The Buy-Sell Agreement
provides that in any transaction in which Doug Voss sells greater than 5% of his
Common Stock, Doug Voss has the right to compel Gayle R. Brandt to include the
Shares held by her in such transaction on the same terms as the shares of Common
Stock held by Doug Voss. In turn, Gayle R. Brandt has the right to have her
Shares included by Doug Voss in any such transaction on a pro rata basis.

         The Buy-Sell Agreement provides Doug Voss with the right to purchase
the Shares of Gayle R. Brandt for the market price upon the death of Gayle R.
Brandt and an involuntary disposition of the Shares held by Gayle R. Brandt.
Pursuant to the Buy-Sell, Doug Voss will vote all shares of Common Stock
beneficially owned by him (including the Shares) for the election of Gayle R.
Brandt to the Board of Directors of the Issuer.

         The Buy-Sell Agreement also gives Gayle R. Brandt the right each year
during the Term of the Buy-Sell Agreement, by giving one hundred eighty (180)
days advance written notice, to require Doug Voss to purchase the Shares owned
by Gayle R. Brandt for a share price to be negotiated or at market price up to a
total purchase amount not to exceed $50,000 per year. This right may not be
exercised more than two (2) times per year. On February 20, 2002, Gayle Brandt
exercised this right and Douglas G. Voss (through Flyers) purchased from her
198,245 shares of Common Stock at a price of $0.504 per share and on September
12, 2003, Gayle Brandt exercised this right and Douglas G. Voss (through Flyers)
purchased from her 172,413 shares of Common Stock at $0.29 per share pursuant to
a Stock Purchase Agreement.

         Doug Voss, as the sole shareholder of Flyers, and Tennenbaum & Co., LLC
have entered into a Co-Sale Agreement with respect to the shares of Great Lakes
Common Stock held by Doug Voss and Flyers. Pursuant to the Co-Sale Agreement,
neither Doug Voss nor Flyers may, either singly or jointly, in any one
transaction or any series of related transactions, directly or indirectly, sell
or otherwise dispose of a number of shares of Common Stock of Great Lakes which
would constitute fifteen percent (15%) or more of the total number of shares of
Common Stock of Great Lakes then issued and outstanding to any third party or
group of third parties (the "Third Party Offer") unless the terms and conditions
of such Third Party Offer shall include an offer to include in the sale or other
disposition to the third party the 500,000 shares of Common Stock of Great Lakes
which were acquired by Tennenbaum & Co., LLC on August 31, 1998 on the same
terms as the sale by Doug Voss and/or Flyers. The right of co-sale provided by
such Co-Sale Agreement does not apply to any sale of Common Stock of Great Lakes
by Doug Voss pursuant to the exercise of the option granted by Doug Voss to
Gayle R. Brandt to acquire his shares of Common Stock of Great Lakes upon the
death of Doug Voss as set forth in the Buy-Sell Agreement as described above.
