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 10-KSB, Form 20-F, Form 11-K, Form N-SAR, 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 the Form 10-K, Form 10-KSB,
20-F, 11-K, 10-Q, 10-QSB, N-SAR, or the transition report or portion thereof,
could not be filed within the prescribed time period.

     The Registrant's Quarterly Report on Form 10-Q for the quarterly period
ended March 31, 2002 cannot be completed within the prescribed time period
because the Registrant is experiencing a delay in finalizing the financial
statements to be included in such Form 10-Q, due to the fact that the Registrant
has recently lost a number of key employees in its finance department. Thus, the
Registrant requires additional time to complete and file its Form 10-Q for the
quarterly period ended March 31, 2002.

     For the reasons set forth above, the Registrant cannot timely file its
Quarterly Report on Form 10-Q without unreasonable effort or expense. The
Registrant is in the process of completing the Form 10-Q and management believes
that this will be after May 15, 2002 but on or before May 20, 2002.
