Plain English Summary

2/10 complexity

This Airworthiness Directive (safety rule) mandates that owners of specific Gulfstream/Grumman American AA-5 series aircraft must inspect their flap surfaces—the moving parts on the wings that help with landing and takeoff.

Who must comply? Only owners of these specific serial numbers:

AA-5: AA5-0600 to AA5-0834
AA5A: AA5A-0001 to AA5A-0013 and AA5A-0015 to AA5A-0017
AA5B: AA5B-0001 to AA5B-0118, plus specific outliers AA5B-0120, AA5B-0123, AA5B-0124, and AA5B-0132

What needs doing? Carry out an inspection of the flap surfaces following the procedures in Grumman American Aviation Service Letter No. 758.

When? Within 100 hours of flight time after 27 February 1976.

Why it matters: Catches structural problems with the flaps before they fail during critical phases of flight—like when you're trying to land the plane.
