Airworthiness Directives; Airbus Model A340 Series Airplanes Equipped With CFM International CFM56-5C Engines

This amendment adopts a new airworthiness directive (AD) that is applicable to certain Model A340 series airplanes. This action requires repetitive inspections of the pivoting door roller fittings of the upper and lower thrust reversers for cracks, and corrective action, if necessary. This action is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. This action is intended to detect and correct cracking of the pivoting door roller fittings of the thrust reversers, which could result in failure of the primary locking mechanism of the thrust reversers during flight, leading to reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
