## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A340 series airplanes. This action requires revising the Airplane Flight Manual (AFM) to provide the flightcrew with procedures to prevent thrust loss during initial climb. This action also requires installing a new or modified electronic control unit on each engine, which, when accomplished, terminates the requirement for the AFM revision. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent significant thrust loss during initial climb, which could result in an increased risk of collision with obstacles in the initial climb path of the airplane.
