Airworthiness Directives; Boeing Model 767 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Boeing Model 767 series airplanes, that requires repetitive inspections to ensure the proper condition of the engine thrust link components, and follow-on corrective action, if necessary; and replacement of the end cap assembly with an improved assembly. Such replacement, when accomplished, terminates the repetitive inspections. This amendment is prompted by a report of fatigue cracking of end cap bolts caused by improper installation. The actions specified by this AD are intended to prevent failure of the end cap assembly, which could lead to separation of the engine from the airplane in the event of a primary thrust linkage failure.
