## Abstract

This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319 and A321 series airplanes, that requires replacement of the actuator of the ram air turbine (RAT) with a new actuator. This amendment also requires modification of the actuator wiring. 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 RAT to deploy in an emergency situation, and consequent loss of electrical and hydraulic systems.
