The request should include an assessment of the effect of the modification, alteration, or repair on the unsafe condition addressed by this AD; and, if the unsafe condition has not been eliminated, the request should include specific proposed actions to address it.
Compliance
Required as indicated, unless accomplished previously. To prevent continuous aft transfer of fuel due to the fuel level sensing amplifier (FLSA) not supplying electrical power to the trim tank overflow sensor, which could result in potential loss of fuel during flight, accomplish the following: (a) Except as provided by paragraph (b) of this AD, within 2 months after the effective date of this AD, remove the FLSA of the trim tank system, modify the polarization pin code in the electronics bay, and install a new, improved FLSA, in accordance with Airbus Service Bulletin A300-28-6055, Revision 01, dated July 24, 1998. Note 2: Accomplishment of the actions specified in paragraph (a) of this AD, prior to the effective date of this AD, in accordance with Airbus Service Bulletin A300-28-6055 dated January 28, 1997, is considered acceptable for compliance with the applicable actions specified in this AD. (b) For airplanes on which Airbus Service Bulletin A300-31-6051, dated June 28, 1996, is accomplished after the effective date of this AD: Concurrent with the accomplishment of Airbus Service Bulletin A300-31-6051, accomplish the actions required by paragraph (a) of this AD, in accordance with Airbus Service Bulletin A300-28- 6055, Revision 01, dated July 24, 1998. (c) As of the effective date of this AD, no person shall install a FLSA having part number 722-295-2, on any airplane. (d) An alternative method of compliance or adjustment of the compliance time that provides an acceptable level of safety may be used if approved by the Manager, International Branch, ANM-116, FAA, Transport Airplane Directorate. Operators shall submit their requests through an appropriate FAA Principal Maintenance Inspector, who may add comments and then send it to the Manager, International Branch, ANM-116. Note 3: Information concerning the existence of approved alternative methods of compliance with this AD, if any, may be obtained from the International Branch, ANM-116.
