We are superseding an existing airworthiness directive (AD) that applies to 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:
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 15 days after June 12, 2009 (the effective date of AD 2009-11-09): Deactivate the electrical supply of SOGERMA 2510112 series pilot seats and SOGERMA 2510113 series co-pilot seats, in accordance with the instructions of Airbus All Operators Telex (AOT) A310-25A2203, Revision 02, dated March 2, 2009; or Airbus AOT A300-25A6215, Revision 02, dated March 2, 2009; as applicable.
(h) For optional intermediate action for restoration of the electrical adjustment of the vertical seat movement only: Deactivating the electrical powered horizontal movement of SOGERMA 2510112 series pilot seats or SOGERMA 2510113 series co-pilot seats, in accordance with the instructions of EADS SOGERMA Alert Service Bulletin A2510112-25-764, Revision 1, dated February 17, 2009, allows restoration of the vertical adjustment only.
(i) For optional intermediate action for restoration of the electrical adjustment of the vertical seat and horizontal seat movement: Inspecting the position of switch `S4' and the related shim of SOGERMA 2510112 series pilot seats or SOGERMA 2510113 series co-pilot seats, in accordance with EADS SOGERMA Inspection Service Bulletin 2510112-25-807, dated February 20, 2009, allows reactivation of both horizontal and vertical electrical movements, provided the measurement results of the inspection are within the acceptable value indicated in that service bulletin, and provided that the inspection is repeated thereafter at intervals not to exceed 2 months. If the measurement result of any inspection is not within the acceptable value indicated in EADS SOGERMA Inspection Service Bulletin 2510112-25-807, dated February 20, 2009, the horizontal movement must be deactivated before further flight.
(j) At the applicable time specified in paragraph (j)(1) or (j)(2) of this AD: Submit a report of the findings for the first inspection done in accordance with paragraph (i) of this AD to Airbus SAS-EAW (Airworthiness Office), 1 Rond Point Maurice Bellonte, 31707 Blagnac Cedex, France. The report must include a detailed fleet inspection report, including measurement values, and pin and serial numbers for each seat.
(1) If the inspection was done on or after June 12, 2009: Submit the report within 30 days after the inspection.
(2) If the inspection was accomplished prior to June 12, 2009: Submit the report within 30 days after June 12, 2009.
(k) Modifications made prior to June 12, 2009, in accordance with EADS SOGERMA Alert Service Bulletin A2510112-25-764, dated December 19, 2008, are considered acceptable for compliance with the applicable action specified in this AD.
Within 12 months after the effective date of this AD: Install an enlarged shim for the horizontal switch actuation on each affected seat, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-25-6217, dated August 31, 2009 (for Model A300-600 series airplanes) or A310-25-2205, Revision 01, dated November 19, 2010 (for Model A310 series airplanes). Doing the installation required by paragraph (l) of this AD terminates the requirements of paragraphs (g), (h), and (i) of this AD.
(m) As of the effective date of this AD, no person may install any SOGERMA 2510112 series pilot seat or SOGERMA 2510113 series co-pilot seat, on any airplane, unless that seat has been modified in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-25-6217, dated August 31, 2009 (for Model A300-600 series airplanes) or A310-25-2205, Revision 01, dated November 19, 2010 (for Model A310 series airplanes).
(n) Actions accomplished before the effective date of this AD according to Airbus Mandatory Service Bulletin A310-25-2205, dated August 31, 2009 (for Model A310 airplanes), are considered acceptable for compliance with the corresponding actions required by paragraphs (l) and (m) of this AD.
Note 1: This AD differs from the MCAI and/or service information as follows: No differences.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
