Airworthiness Directives; Airbus Model A330 and A340 Series Airplanes

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires a one-time inspection of the free-fall actuators of the landing gear for discrepancies, and replacement of discrepant actuators with new, improved actuators. This action also requires eventual replacement of certain free-fall actuators. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent electrical short circuits to the free-fall actuators of the landing gear, which could result in failure to extend the landing gear, and consequent damage to the airplane structure during landing.
