Airworthiness Directive · Amendment 39-9261 · Airbus Airplanes
Airbus Airplanes
This AD applies to Airbus A340-211, A340-311.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A340 series airplanes. This action requires a one-time inspection of the fuel flow from the main fuel supply hose/tube assembly, and repair, if necessary. This amendment is prompted by a report of a low pressure fuel valve found with the internal thermal relief valve assembled in the wrong position on one airplane. The actions specified in this AD are intended to prevent overpressurization of the fuel supply line due to the incorrect positioning of the internal thermal relief valve. Such overpressurization could cause the fuel pipe coupling to separate and allow fuel to leak into the engine pylon, thus posing a fire hazard.
