Unsafe Condition

Reports of cracks in the skins and stringers at the end fasteners common to the stringer end fittings at stations Xw=408 and Xw=-408 wing splice joints. Fatigue cracking in these areas could result in wing structure that might not sustain limit load, leading to loss of structural integrity of the wing.

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

Required Actions

Inspect the lower skin and stringers at stations Xw=408 and Xw=-408 for cracks. Perform corrective actions if necessary, as specified in the AD.

Compliance Time

Before the accumulation of 20,000 total flight cycles, or within 1,500 flight cycles or 2 years after the date of the service bulletin, whichever occurs later.
