Unsafe Condition
Failure of the wing skin at the top aft outboard corner of the battery box, which could result in structural damage to the wing.
AI-generated summary from the source AD text. Verify against the official source before acting.
Required Actions
Visually inspect the right and left upper wing skin by the top aft outboard corner of the battery box for cracks in accordance with specified service bulletins. If cracks are found, dye penetrant inspect the 27-31130 straps in the wheel wells. If cracks are not found, reinspect within 500 hours time-in-service or modify the wing skin to terminate further inspections.
