Airworthiness Directive · Amendment 39-10535 · Airbus Model A300, A310, and A300-600 Series Airplanes
Airbus Model A300, A310, and A300-600 Series Airplanes
Model A300, A310, and A300-600 series airplanes; on which Airbus Modification 8928 or 6094 has not been installed; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300, A310, and A300-600 series airplanes, that requires replacement of the non-return valves located in the engine fuel feed lines on the outer fuel tank with new return valves; and, for certain airplanes, replacement of the inner tank booster pump canisters with modified canisters. This amendment is prompted by issuance of mandatory continuing airworthiness information by a foreign civil airworthiness authority. The actions specified by this AD are intended to prevent sticking of non-return valves located in the fuel system, which could result in an internal fuel transfer from the center tank to the inner or outer tank. Such a transfer of fuel could lead to fuel spillage overboard through the vent system, and consequent insufficient fuel for the airplane to reach its flight destination.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
