Airworthiness Directives; Airbus Model A340-211, -212, -213, - 311, -312, and -313 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to all Airbus Model A340-211, -212, -213, -311, -312, and - 313 series airplanes. This action requires repetitive operational tests to ensure proper operation of the actuator of the secondary locks of the thrust reversers; and corrective actions, if necessary. 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 the inadvertent opening of a thrust reverser door in the event of failure of the primary and secondary locks of the thrust reverser. Such inadvertent opening could result in reduced controllability of the airplane.
