## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300, A300-600, and A310 series airplanes, that requires replacement of the transformer rectifier units (TRU) in the avionics compartment with new, improved TRU's. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent failure of the TRU's. Failure of multiple TRU's could result in loss of the thrust reversers, autothrottle, flaps, and various systems (wing/cockpit window anti-ice, trim tank pumps, and windshield wipers) on the airplane; or incorrect information displayed to the flight crew.
