## Summary

We propose to adopt a new airworthiness directive (AD) for certain airplanes, originally manufactured by Lockheed Martin Aeronautics Company for the military as P-3A or P3A airplanes. This proposed AD was prompted by a determination that the existing maintenance program must be revised to address fatigue cracking of the airplane. This proposed AD would require revising the maintenance or inspection program, as applicable, to incorporate certain limitations. We are proposing this AD to detect and correct fatigue cracking, which could result in reduced structural integrity of the airplane.
