Airworthiness Directive · Amendment 39-14014 · Airbus Model A319, A320, and A321 Series Airplanes
Airbus Model A319, A320, and A321 Series Airplanes
This AD applies to Airbus Model A319, A320, and A321 series airplanes; certificated in any category; equipped with any Hamilton Sundstrand Auxiliary Power Unit (APU) alternating current (AC) generator having part number 5906732, 5909006, or 5910047; with up to amendment 17 included; on which Airbus Modification 32614 has not been done.
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Model A319, A320, and A321 series airplanes. This AD requires modification of certain auxiliary power unit (APU) alternating current (AC) generators. This AD is prompted by a report of an explosion in the APU compartment, which blew open the compartment doors. We are issuing this AD to prevent oil vapor leakage from the APU AC generator, which, when combined with an electric arc at the electrical receptacle, could result in a fire or explosion in the APU compartment during flight.
You are responsible for having the actions required by this AD performed within the compliance times specified, unless the actions have already been done.
Within 20 months after the effective date of this AD, modify the APU AC generator by doing all the actions in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-24-1106, Revision 01, dated May 13, 2004.
Note 1: Airbus Service Bulletin A320-24-1106, Revision 01, refers to Hamilton Sundstrand Service Bulletin 90EGS01AG-24-18, dated February 13, 2003, as an additional source of service information for accomplishment of the modification required by paragraph (f) of this AD.
Modification of the APU AC generator accomplished before the effective date of this AD in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-24-1106, dated May 26, 2003, is acceptable for compliance with the modification required by paragraph (f) of this AD.
