Unsafe Condition

Stress corrosion cracking of the auxiliary spar cap could cause excessive loads to the structure attaching the support fitting of the main landing gear (MLG) to the wing, resulting in loss of the MLG.

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

Required Actions

Inspect the material composition of the lower inboard auxiliary spar cap of the left and right wings. For certain airplanes, perform repetitive detailed and dye penetrant inspections for cracking of the spar cap, and take corrective actions if necessary.
