Airworthiness Directive · Amendment 39-11043 · Airbus Model A300-600 Series Airplanes
Airbus Model A300-600 Series Airplanes
Model A300-600 series airplanes on which Airbus Modification 4801 was accomplished during production and on which Airbus Modification 10778 (reference Airbus Service Bulletin A300- 31-6051, dated June 28, 1996) has been accomplished; except those airplanes on which Airbus Modification 11683 (reference Airbus Service Bulletin A300-28-6055, dated January 28, 1997, and Revision 01, dated July 24, 1998) has been accomplished; certificated in any category.
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A300-600 series airplanes, that requires removal of the fuel level sensing amplifier (FLSA) of the trim tank system, modification of the polarization pin code in the electronics bay, and installation of a new, improved FLSA. 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 continuous aft transfer of fuel due to the FLSA not supplying electrical power to the trim tank overflow sensor, which could result in potential loss of fuel during flight.
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.
