Airworthiness Directive · Amendment 39-15088 · Airbus Model A330 and A340 Airplanes
Airbus Model A330 and A340 Airplanes
Superseded. A later AD replaced this one: AD 2007-18-04. Comply with the one in force.
This AD applies to Airbus Model A330 and A340 airplanes; certificated in any category; all certified models, all serial numbers; for which the date of issuance of the original French standard airworthiness certificate or the date of issuance of the original export certificate of airworthiness is before March 1, 2007.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) originated by an aviation authority of another country to identify and correct an unsafe condition on an aviation product. The MCAI describes the unsafe condition as:
Unless already done, do the following actions.
(1) Within 63 days after the effective date of this AD, in accordance with the instructions of Airbus All Operators Telex (AOT) A330-24A3042, A340-24A4056, or A340-24A5020, all Revision 02, all dated April 12, 2007; as applicable: Inspect the inlet screen (last chance filter) for the generator scavenge-oil pump for signs of debris and, as applicable, apply all associated corrective actions before further flight.
(2) For Model A330 aircraft operating under MMEL (master minimum equipment list) Item 24-22-01 ‘AC Main Generation' or MMEL Item 36-11-01 ‘Bleed Air Supply System Failure': As of the effective date of this AD, before each flight, perform a check of the differential pressure indicator button on the lube filter and the generator scavenge filter in accordance with the instructions of Airbus AOT A330-24A3042, Revision 02, dated April 12, 2007.
Note 1: The repetitive checks before each flight specified in paragraph (f)(2) of this AD are not required for airplanes operated under MMEL Item 36-11-01, provided the APU generator has been removed or deactivated in accordance with the instructions of Airbus AOT A330-24A3042, Revision 02, dated April 12, 2007.
(3) Actions done before the effective date of this AD in accordance with the applicable Airbus service information in Table 1 of this AD are acceptable for compliance with the corresponding provisions of paragraph (f) of this AD.

Note 2: This AD differs from the MCAI and/or service information as follows: Although the MCAI or service information requires checking the differential pressure indicator button on the lube and the generator scavenge filter until May 31, 2007, this AD does not provide a termination date for the checks. This difference has been coordinated with the European Aviation Safety Agency (EASA).
