Airworthiness Directives; Airbus Model A330, A340-200, and A340-300 Series Airplanes

요약

This amendment adopts a new airworthiness directive (AD); applicable to certain Airbus Model A330, A340-200, and A340-300 series airplanes; that requires inspecting the ram air turbine (RAT) actuator to determine its serial number; and re-identifying the RAT actuator, inspecting the RAT actuator to determine whether the rotary solenoids are in the correct position, and replacing the RAT actuator, as applicable. This action is necessary to prevent failure of the RAT actuator to deploy when necessary during flight, which could result in reduced controllability of the airplane. This action is intended to address the identified unsafe condition.
