Unsafe Condition
Cracks in the wing spar carry-through lower cap strip adjacent to elongated holes and associated rivet holes, and cracks in the fuselage mounted wing attachment brackets and forward/aft frame plates of the wing spar carry-through, which could lead to inflight wing separation.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Inspect and modify the wing spar carry-through lower cap strip by removing landing gear brackets, drilling out rivets, polishing surfaces, conducting ultrasonic and eddy current tests for cracks, reaming rivet holes, inserting HI-LOK rivets, reinstalling components, and replacing rubber bearings. Perform ultrasonic tests on wing attachment brackets and visual inspections of frame plates. Update AFM limitations, install placards prohibiting acrobatic flight, and conduct recurring ultrasonic tests every 500 hours time-in-service. Ferry flights require specific inspections if previously used for acrobatics.
