## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757-200 series airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the side panel-to-frame attachments and frames of the aft cargo compartment are subject to widespread fatigue damage (WFD). This proposed AD would require an inspection of the side panel- to-frame attachments and frames to verify that certain modifications have been done, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
