## Summary

We propose to adopt a new airworthiness directive (AD) for all Lockheed Martin Corporation/Lockheed Martin Aeronautics Company Model 382, 382B, 382E, 382F, and 382G airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the outer wings are subject to widespread fatigue damage (WFD). This proposed AD would require replacing certain outer wings with new or certain serviceable outer wings. We are proposing this AD to prevent fatigue cracking of the outer wing, and to prohibit exceeding the limit of validity (LOV), which could result in reduced structural integrity of the airplane.
