Abstract
This amendment adopts a new airworthiness directive (AD) that is applicable to certain Airbus Model A330-223, -321, -322, and -323 series airplanes equipped with Pratt & Whitney Model PW4164, PW4168, or PW4168A engines. This action requires modification of the primary structure of the engine pylons, and replacement of the thrust reverser locking actuators with new, improved locking actuators. This action is necessary to prevent reduced structural integrity of the primary structure of the engine pylons, and uncommanded deployment of the thrust reversers, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
