## Summary

This document proposes the adoption of a new airworthiness directive (AD) that is applicable to certain Airbus Model A330, A340-200, and A340-300 series airplanes. This proposal would require inspecting the ram air turbine actuator (RAT) 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.
