Action
Final rule.
Summary
We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200 Freighter series airplanes; Model A330-200 and A330-300 series airplanes; Model A340-200 and A340-300 series airplanes; Model A340-500 series airplanes; and Model A340-600 series airplanes. This AD was prompted by a report indicating that, during an operational test of a ram air turbine (RAT), the RAT did not deploy in automatic mode. This AD requires identification of the manufacturer, part number, and serial number of the RAT, and re-identification and modification of the RAT if necessary. We are issuing this AD to prevent non-deployment of the RAT, which, if preceded by a total engine flame- out, or during a total loss of normal electrical power generation, could result in reduced control of the airplane.
