## Summary

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