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:
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 400 flight cycles after the effective date of this AD, for each engine, inspect to determine the part number of the forward engine mounting yoke, in accordance with Airbus All Operators Telex A300-71A6029 or A310-71A2036, both dated March 30, 2010, as applicable. A review of airplane maintenance records is acceptable in lieu of this inspection if the part number of the yoke can be conclusively determined from that review.
(1) If the inspection required in paragraph (g) of this AD finds any mounting yoke is a skinny cast yoke having part number (P/N) 9383M43G08, 9383M43G09, 9383M43G10, or 9383M43G11, do a detailed inspection of the yoke to determine if it is ruptured, in accordance with Airbus All Operators Telex A300-71A6029 or A310-71A2036, both dated March 30, 2010, as applicable.
(i) If the mounting yoke is ruptured, before further flight, repair in accordance with a method approved by the FAA or the European Aviation Safety Agency (EASA) or its delegated agent.
(ii) If the mounting yoke is not ruptured, within 7,000 flight cycles after the effective date of this AD replace the skinny cast yoke with a forged yoke, in accordance with Airbus All Operators Telex A300-71A6029 or A310-71A2036, both dated March 30, 2010, as applicable.
(2) At the applicable time specified in paragraph (g)(2)(i) or (g)(2)(ii) of this AD, report to Airbus the findings of the inspection required by paragraph (g)(1) using Appendix 02 and Appendix 03, as applicable, of Airbus All Operators Telex A300-71A6029 or A310-71A2036, both dated March 30, 2010, as applicable. Send the report to Laure Dupland, SEEE3; Customer Services; telephone +33 (0)5 61 18 20 24; fax +33 (0)5 61 93 36 14; e-mail laure.dupland@airbus.com.
(i) If the inspection was done on or after the effective date of this AD: Submit the report within 30 days after the inspection.
(ii) If the inspection was done before the effective date of this AD: Submit the report within 30 days after the effective date of this AD.
(h) Prior to or concurrent with the actions required by paragraph (g)(1)(ii) of this AD, install a redesigned forward engine mount system in accordance with the Accomplishment Instructions of GE CF6-80C2 Service Bulletin 72-0222, Revision 4, dated February 29, 2000.
(i) As of the effective date of this AD, do not install any forward engine mount skinny cast yoke having P/N 9383M43G08, 9383M43G09, 9383M43G10, or 9383M43G11, on any airplane.
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.
