Airworthiness Directives; The Boeing Company Airplanes

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