Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200 freighter series airplanes, Model A330- 200 and -300 series airplanes, and Model A340-200, -300, -500, and -600 series airplanes. This proposed AD was prompted by reports of the ram air turbine (RAT) not deploying when tested. This proposed AD would require identification of the supplier, part number, and serial number of the installed RAT actuator, and re-identification of the actuator and RAT, or replacement of the RAT actuator with a serviceable unit and re-identification of the RAT, if necessary. We are proposing this AD to prevent non-deployment of the RAT, which if occurred following a total engine flame-out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane.
