## Summary

We propose to adopt a new airworthiness directive (AD) for certain The Boeing Company Model 757 airplanes. This proposed AD was prompted by an evaluation by the design approval holder (DAH) indicating that the inner skin at the lower fastener row is subject to widespread fatigue damage (WFD). This proposed AD would require a general visual inspection of certain lap splice inspection areas for any repair common to the fuselage skin lap splice inspection areas, repetitive dual frequency eddy current (DFEC) inspections of a certain lap splice inner skin for any crack, and applicable on-condition actions. We are proposing this AD to address the unsafe condition on these products.
