Summary
The FAA proposes to adopt a new airworthiness directive (AD) for all Airbus Model A300 airplanes and Model A310 airplanes and for certain Airbus Model A300-600 series airplanes. This proposed AD would require an inspection of the wing and center fuel tanks to determine if certain P-clips are installed and corrective action if necessary. This proposed AD also would require an inspection of electrical bonding points of certain equipment in the center fuel tank for the presence of a blue coat and related investigative and corrective actions if necessary. This proposed AD also would require installation of new bonding leads and electrical bonding points on certain equipment in the wing, center, and trim fuel tanks, as necessary. This proposed AD results from fuel system reviews conducted by the manufacturer. We are proposing this AD to ensure continuous electrical bonding protection of equipment in the wing, center, and trim fuel tanks and to prevent damage to wiring in the wing and center fuel tanks, due to failed P- clips used for retaining the wiring and pipes, which could result in a possible fuel ignition source in the fuel tanks.
