Unsafe Condition

Fatigue cracking on the connecting angle between frame 56 and the right-hand frame support at stringer 38, which could result in reduced structural integrity of the airplane.

AI-generated summary from the source AD text. Verify against the official source before acting.

Required Actions

Perform a visual inspection for fatigue cracking on the connecting angle. If no cracking is detected, either replace the connecting angle with a new part or repeat the inspection at intervals not exceeding 12,000 flight cycles. If cracking is detected, replace the connecting angle prior to further flight.
