Airworthiness Directive · Amendment 39-13680 · Airbus Model A319, A320, and A321 Series Airplanes
Airbus Model A319, A320, and A321 Series Airplanes
Model A319, A320, and A321 series airplanes, certificated in any category; except those airplanes on which Airbus Modification 30737 has been accomplished in production (reference Airbus Service Bulletin A320-24-1099, Revision 02, dated February 11, 2003, in service).
This amendment adopts a new airworthiness directive (AD), applicable to certain Airbus Model A319, A320, and A321 series airplanes. This AD requires replacement of a certain transformer rectifier unit (TRU) with a certain new TRU. This action is necessary to prevent ignition of the input filter capacitors of the TRU in position 2 of the avionics compartment, which could potentially result in smoke in the cockpit. This action is intended to address the identified unsafe condition.
To prevent ignition of the input filter capacitors of the transformer rectifier unit (TRU) in position 2 of the avionics compartment, which could potentially result in smoke in the cockpit, accomplish the following:
(a) Prior to the accumulation of 15,000 total flight hours, or within 16 months after the effective date of this AD, whichever occurs later, replace the TRU, part number Y005-2, with a new TRU, part number Y005-3, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-24-1099, Revision 02, dated February 11, 2003.
(b) Replacements accomplished before the effective date of this AD per Airbus Service Bulletin A320-24-1099, dated March 5, 2002; or Revision 01, dated July 26, 2002; are considered acceptable for compliance with the corresponding action specified in this AD.
(c) As of the effective date of this AD no person shall install a TRU, part number Y005-2, within position 2 of the avionics compartment on any airplane.
(d) In accordance with 14 CFR 39.19, the Manager, International Branch, ANM 116, Transport Airplane Directorate, FAA, is authorized to approve alternative methods of compliance (AMOCs) for this AD.
(e) Unless otherwise specified in this AD, the actions shall be done in accordance with Airbus Service Bulletin A320-24-1099, Revision 02, dated February 11, 2003. This incorporation by reference was approved by the Director of the Federal Register in accordance with 5 U.S.C. 552(a) and 1 CFR part 51.
