Unsafe Condition
Certain fuselage frames are subject to widespread fatigue damage, leading to fatigue cracks in the fuselage skin that can propagate and grow, resulting in reduced structural integrity and sudden decompression of the airplane in flight.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Conduct repetitive inspections for skin cracks at specified shear tie end fastener locations of the fuselage frames, using either external detailed or high frequency eddy current (HFEC) inspections. Repair cracks if necessary. For airplanes with certain existing repair doublers, conduct repetitive inspections for skin cracks next to the shear tie and take corrective actions if necessary.
