## Summary

The FAA proposes to adopt a new airworthiness directive (AD) for certain McDonnell Douglas Model DC-8-61, DC-8-61F, DC-8-63, DC-8- 63F, DC-8-71F, and DC-8-73F airplanes. For certain airplanes, this proposed AD would require non-destructive testing (NDT) to detect cracks of the door jamb corners of the forward and aft service doors, and doing applicable related investigative and corrective actions. For certain other airplanes, this proposed AD would require inspecting and repairing if necessary or replacing previously repaired door jamb corners with an applicable repair. This proposed AD results from reports of numerous cases of cracks in the skin at the door jamb corners of the forward and aft service doors. We are proposing this AD to detect and correct fatigue cracking of door jamb corners of the forward and aft service doors, which could adversely affect the structural integrity of the airplane.
