Airworthiness Directive · Amendment 39-10277 · Airbus Model A330 and A340 Series Airplanes
Airbus Model A330 and A340 Series Airplanes
Superseded. A later AD replaced this one: AD 2000-06-08. Comply with the one in force.
Model A330-301, -321, -322, -341, and -342 series airplanes on which Airbus Modification 45631 has not been installed; and Model A340-211, -212, -213, -311, -312, and -313 series airplanes on which Airbus Modification 45485 has not been installed; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A330 and A340 series airplanes. This action requires repetitive operational tests of the override mechanism of the trimmable horizontal stabilizer (THS) to determine if the system functions correctly; and corrective action, if necessary. This amendment is prompted by the issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified in this AD are intended to prevent uncommanded movement of the THS, which could result in reduced controllability of the airplane.
