If the notification relates to a portion of the filing checked above, identify
the Item(s) to which the notification relates: N/A

PART I - REGISTRANT INFORMATION

Full Name of Registrant:                    Great Lakes Aviation, Ltd.
Former Name if Applicable:
Address of Principal Executive Office:      1022 Airport Parkway
City, State and Zip Code:                   Cheyenne, Wyoming 82001

PART II - RULES 12b-25(b) and (c)

If the subject report could not be filed without unreasonable effort or expense
and the registrant seeks relief pursuant to Rule 12b-25, the following should be
completed. (Check box if appropriate)

[X]   (a)      The reasons described in reasonable detail in Part III of this
               form could not be eliminated without unreasonable effort or
               expenses;



[X]   (b)      The subject annual report, semi-annual report, transition report
               on Form 10-K, Form 20-F, Form 11-K, Form N-SAR or Form N-CSR, or
               portion thereof, will be filed on or before the fifteenth
               calendar day following the prescribed due date; or the subject
               quarterly report or transition report on Form 10-Q, or portion
               thereof, will be filed on or before the fifth calendar day
               following the prescribed due date; and

[_]   (c)      The accountant's statement or other exhibit required by Rule
               12b-25(c) has been attached if applicable.

PART III - NARRATIVE

State below in reasonable detail the reasons why Forms 10-K, 20-F, 11-K, 10-Q,
N-SAR, N-CSR, or the transition report or portion thereof, could not be filed
within the prescribed time period.

     The Registrant's Annual Report on Form 10-K for the year ended December 31,
2002 cannot be completed within the prescribed time period, because the
Registrant has been in the process of determining the accounting treatment of,
and negotiating certain terms relating to, a complex financial restructuring. As
a consequence, completion of the Registrant's financial statements has been
delayed.

     For the reasons set forth above, the Registrant cannot timely file its
Annual Report on Form 10-K without unreasonable effort or expense. The
Registrant is working to complete the Form 10-K, and management believes that
the Form 10-K will be filed on or before April 15, 2003.
