Summary
This document proposes the adoption of a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes. The proposed AD would require checking the identification plate on the ram air turbine (RAT) actuator and re-identifying the actuator or replacing the actuator with one which has been cleaned and tested by its manufacturer. This proposal is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by the proposed AD are intended to prevent jamming of the RAT actuator in an emergency which requires deployment of the RAT, and consequent loss of hydraulic and electrical power in the airplane.
