  1. Note:  This is an accelerated overview course. It is the responsibility of the student to use supplemental information on subjects that are not fully understood. At the instructor’s discretion, a student without a current “A” airframe certificate issued from the FAA in good standing will be required to review and test on supplemental material available (on CD-ROM) for check out from the Aviation Technology Center’s tool crib. Proof of current enrollment is required.

Effective Term:
