Unsafe Condition
Fatigue cracking of the fuselage, 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 or eddy current inspection to detect cracking in the upper rivet row of the longitudinal lap joint prior to 20,000 total flight cycles or within 6 months after the AD's effective date, whichever is later. Repeat inspections every 4,000 flight cycles (if using visual techniques) or 12,000 flight cycles (if using eddy current techniques). Repair any cracks found before further flight.
