It requires inspections for existing repairs, inspections for any crack of the fuselage skin, bear strap, and stub frame, repetitive inspections for any crack of the bear strap and stub frame, and applicable on-condition actions. The AD aims to address the unsafe condition on these products to ensure structural integrity and safety.
