Plain English Summary

4/10 complexity

This AD requires operators of specified Airbus A319/A320 aeroplanes to inspect overwing emergency-exit door frame rivets and, if needed, remove affected rivets and inspect interior countersinks following Airbus Service Bulletin A320‑53‑1147 (designated revisions). Inspections must be repeated every 3,500 flight cycles until rivets are removed; rivet removal must be completed before 24,000 flight cycles. The measure responds to reports of loose or out‑of‑tolerance rivets that could impair exit-frame structural integrity.

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.
