Background: A report was received of a loose ABS213 rivet at the overwing emergency exit door frame corners of A320 and A319 aircraft. Further investigation revealed several instances where the grip length of the rivets was slightly out of tolerance. This condition could affect the structural integrity of the overwing exit frame in the long term.

Amendment 1 introduced a supplemental inspection program to verify/measure affected rivet hole interior countersinks, and clarified Requirement 1 compliance.
