We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued by an airworthiness authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as a fire in the auxiliary power unit air intake. We are issuing this AD to require actions to correct the unsafe condition on these products.
Unless already done, do the following actions except as stated in paragraph (f) below.
(1) Within the next 600 flight hours following the effective date of this AD: Inspect the APU starter motor, APU air inlet plenum, and APU air intake, and do the applicable corrective actions before further flight, in accordance with the instructions given in Airbus Service Bulletin A320-49-1068, Revision 01, dated February 2, 2006.
(2) Repeat the inspection per above paragraph (e)(1) of this AD, at intervals not exceeding 600 flight hours.
(3) Prior to the accumulation of 2,400 flight hours since the aircraft's first flight, or within the next 600 flight hours after the effective date of this AD, whichever occurs later, unless accomplished before the effective date of this AD in accordance with Airbus Service Bulletin A320-49-1068, dated June 2, 2005: Clean the APU air intake in accordance with the instructions given in Airbus Service Bulletin A320-49-1068, Revision 01, dated February 2, 2006.
