## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires repetitive inspections to detect fatigue cracking of the pitch load fittings of the wing front spar, and rework, if necessary. This amendment also provides for optional terminating action for the repetitive inspections required by this AD. This amendment is prompted by a structural fatigue analysis that shows that the operational loads of the nacelle are higher than the loads used during initial design of the Model 767. The actions specified by this AD are intended to detect and correct fatigue cracking in the pitch load fittings of the wing front spar, which could result in reduced structural integrity of the strut.
