Abstract
The FAA is adopting a new airworthiness directive (AD) for certain transport category airplanes, identified above. This AD requires repetitive inspections for cracks of the doorjamb corners of the main cabin cargo door, and repair if necessary. This AD also provides an optional preventive modification that extends certain repetitive intervals. This AD results from reports of cracks in the fuselage skin at the corners of the doorjamb for the main cabin cargo door. We are issuing this AD to detect and correct fatigue cracks in the fuselage skin, which could result in rapid decompression of the airplane.
