Boeing Model 767-300 Series Airplanes Equipped With Rolls Royce RB211-524H Series Engines
Model 767-300 series airplanes, line numbers 001 through 810 inclusive, certificated in any category, and equipped with Rolls Royce RB211-524H series engines.
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Boeing Model 767-300 series airplanes equipped with Rolls Royce RB211-524H series engines. This action requires re- routing a certain wire bundle containing control wiring for the thrust reverser actuation system. This action is necessary to ensure that control wiring for the thrust reverser actuation system is adequately separated. Inadequately separated wiring could allow a single failure to result in uncommanded deployment of a thrust reverser and consequent reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
