Unsafe Condition

Fatigue cracking in the wing and horizontal stabilizer side-of-body joints, and the fuselage skin circumferential splices, due to high cyclic loads, could connect to form large cracks and result in reduced structural integrity leading to rapid decompression and consequent loss of control of the airplane.

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

Required Actions

Perform one-time detailed and high frequency eddy current inspections for cracks in the wing and horizontal stabilizer side-of-body joints and the fuselage skin circumferential splices, and repair if necessary. For certain airplanes, perform repetitive detailed inspections for cracks of the fuselage skin circumferential splices, and repair if necessary. Report positive findings to Boeing.

Compliance Time

Within 28,500 to 30,000 total flight cycles or 130,000 to 135,000 total flight hours, whichever occurs later.
