Airbus Model A310-221, -222, -322, -324, and -325 Airplanes, and Model A300 B4-620, B4-622, B4-622R, and F4-622R Airplanes, Equipped With Pratt & Whitney PW4000 or JT9D-7R4 Series Engines
This AD applies to Airbus Model A310-221, -222, -322, -324, and -325 airplanes, and Model A300 B4-620, B4-622, B4-622R, and F4-622R airplanes, all serial numbers; certificated in any category; equipped with Pratt & Whitney PW4000 or JT9D-7R4 series engines.
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) Before the accumulation of 30,000 total flight cycles since first flight of the airplane, or within 1,200 flight cycles after the effective date of this AD, whichever occurs later: Replace the non-serialized T/R center latch LH (left hand) and RH (right hand) sides, having part number (P/N) 221D0029-11 and P/N 221D0029-13, with a serialized T/R center latch having P/N 221D0029-15 in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-78-6029 (for Model A300 B4-620, B4-622, B4-622R, and F4-622R airplanes) or A310-78-2030 (for Model A310-221, -222, -322, -324, and -325 airplanes), both including Appendix 1, both dated October 3, 2008.
(2) Within 1,200 flight cycles after accomplishing the replacement required by paragraph (f)(1) of this AD: Perform a detailed inspection for surface cracking of the T/R center serialized latches having P/N 221D0029-15, in accordance with the Accomplishment Instructions of Pratt &Whitney Service Bulletins PW4NAC 78-113 (for airplanes equipped Pratt & Whitney PW4000 series engines) and PW7R4 78-182 (for airplanes equipped JT9D-7R4 series engines), both dated August 15, 2005; as applicable. If any crack is found, before further flight, replace the serialized T/R center latch with a new serialized T/R center latch in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-78-6029 or A310-78-2030, both including Appendix 1, both dated October 3, 2008; as applicable. Repeat the inspection thereafter at intervals not to exceed 1,200 flight cycles.
Note 1: Concurrent accomplishment of the inspections required by paragraph (f)(2) of this AD, with the inspections for engine pylon T/R hinges specified by ALI Task 54-50-28, is recommended.
(3) Before the accumulation of 18,000 total flight cycles since accomplishing the most recent replacement required by paragraph (f)(1) or (f)(2) of this AD: Replace the serialized T/R center latch having P/N 221D0029-15 with a new serialized T/R center latch having P/N 221D0029-15 in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A300-78-6029 (for Model A300 B4-620, B4-622, B4-622R, and F4-622R) or A310-78-2030 (for Model A310-221, -222, -322, -324, and -325 airplanes), both including Appendix 1, both dated October 3, 2008. Replacement of the center latches does not constitute terminating action for the repetitive inspections required by paragraph (f)(2) of this AD.
Note 2: 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.
