AD FAA-2013-0463

We are adopting a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes. This AD was prompted by a report that a certain wire harness located in the tail cone has wiring of a narrower gauge than design requires. This AD requires replacing the affected wire harness. We are issuing this AD to prevent damage to the affected wiring, which could create an ignition source in an area that might contain fuel vapors, possibly resulting in an uncontrolled fire and subsequent loss of the airplane.
