                                    PART III
                                    NARRATIVE

         State below in reasonable detail the reasons why Form 10-K, 11-K, 20-F,
10-Q, N-SAR or the transition report portion thereof could not be filed within
the prescribed time period. (Attach extra sheets if needed.)

         The fiscal year of Environmental Tectonics Corporation (the "Company")
ended on February 22, 2002. Accordingly, the Company's Annual Report on Form
10-K is required to be filed by May 23, 2002. The Company is in the process of
finalizing an amendment to its credit facility. This amendment will impact the
classification of the related borrowings to be reported on the Company's balance
sheet for the fiscal year ended February 22, 2002. Accordingly, the Company
requires additional time to prepare its Annual Report on Form 10-K. The
foregoing reasons causing the Company's inability to timely file its Annual
Report on Form 10-K for the fiscal year ended February 22, 2002 could not be
eliminated without unreasonable effort or expense.

                                     PART IV
                                OTHER INFORMATION

(Name)                            (Area Code)            Telephone Number

         (2) Have all other periodic reports required under Section 13 or 15(d)
of the Securities Exchange Act of 1934 or Section 30 of the Investment Company
Act of 1940 during the preceding 12 months or for such shorter period that the
registrant was required to file such report(s) been filed? If the answer is no,
identify report(s).

         [X] Yes                  [ ] No


         (3) Is it anticipated that any significant change in results of
operations from the corresponding period for the last fiscal year will be
reflected by the earnings statements to be included in the subject report or
portion thereof?

         [ ] Yes                  [X] No

         If so, attach an explanation of the anticipated change, both
narratively and quantitatively, and, if appropriate, state the reasons why a
reasonable estimate of the results cannot be made.
