Airworthiness Directive · Amendment 39-13529 · Airbus Model A319, A320, and A321 Series Airplanes
Airbus Model A319, A320, and A321 Series Airplanes
Model A320 series airplanes which have received modification 27189; Model A319 series airplanes; and Model A321 series airplanes, provided that none has received modification 30978 or 28413; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes, that requires 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 action is necessary 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. This action is intended to address the identified unsafe condition.
