## Abstract

The FAA is superseding an existing airworthiness directive (AD) that applies to all Airbus Model A300 and A310 airplanes, and certain Model A300-600 series airplanes. That AD currently requires an inspection of the wing and center fuel tanks to determine if certain P- clips are installed and corrective action if necessary. That AD also requires 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. That AD also requires installation of new bonding leads and electrical bonding points on certain equipment in the wing, center, and trim fuel tanks, as necessary. This new AD requires, for certain airplanes, installation of bonding on an additional bracket and modification of the fuel/defuel valves on the left-hand wing. This AD results from fuel system reviews conducted by the manufacturer. We are issuing 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.
