Summary
We propose to adopt a new airworthiness directive (AD) for certain Airbus Model A330-200, -200 Freighter, and -300 series airplanes. This proposed 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 proposed AD would require replacing the affected wire harness. We are proposing 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.
