Airworthiness Directive · Amendment 39-15965 · Hydraulic power
Airbus Model A318, A319, A320, and A321 Airplanes
This AD applies to all Airbus Model A318, A319, A320, and A321 airplanes, certificated in any category; except airplanes on which Airbus Modification 27189 was done in production or Airbus Service Bulletin A320-29-1100 was done in service, and on which Airbus Modification 28413 was not done in production.
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 15 months after the effective date of this AD: Identify the part number (P/N) and serial number (S/N) of the RAT in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-29-1122, dated July 27, 2006.
(2) For airplanes on which a RAT with P/N 680203037 is installed that has a S/N between 0101 and 0354 inclusive: Within 15 months after the effective date of this AD, replace the gerotor pump assembly and re-identify the RAT in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-29-1122, dated July 27, 2006.
(3) For airplanes on which a RAT with P/N 680203037 is installed that does not have a S/N between 0101 and 0354 inclusive, or a RAT with a P/N other than P/N 680203037 is installed: No further action is required by this AD.
Note 1: This AD differs from the MCAI and/or service information as follows: Although Appendix 01 of Airbus Service Bulletin A320-29-1122, dated July 27, 2006, tells you to submit information to the manufacturer, this AD specifies that such submittal is not required.
