Airworthiness Directives; The Boeing Company Airplanes

Краткое содержание

We propose to adopt a new airworthiness directive (AD) for all The Boeing Company Model 767-200, -300, and -400ER series airplanes. This proposed AD was prompted an evaluation by the design approval holder (DAH) indicating that the fuselage skin lap splices are subject to widespread fatigue damage (WFD). This proposed AD would require repetitive inspections to detect any crack in the fuselage skin at the skin lap splices. We are proposing this AD to detect and correct cracks at the fuselage skin lap splice, which can rapidly link up, possibly resulting in rapid decompression and loss of structural integrity of the airplane.
