Airworthiness Directive · Amendment 39-15709 · Nacelles/pylons
Airbus Model A310 Series Airplanes
This AD applies to Airbus Model A310-203, -204, and -304 airplanes, all serial numbers, certificated in any category; excluding airplanes that have received Airbus Modification 11110 during production or that have been modified in service in accordance with Airbus Service Bulletin A310-54-2032 (Airbus Modification 11109).
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) Perform a high frequency eddy current (HFEC) inspection and a detailed visual inspection on the lower side of Rib 5 of the left-hand and right-hand pylons, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A310-54-2036, Revision 02, dated September 28, 2007. Do the inspections at the times specified in paragraph (f)(1)(i) or (f)(1)(ii) of this AD, as applicable.
(i) For Model A310-203 and -204 airplanes: Inspect at the later of the times specified in paragraphs (f)(1)(i)(A) and (f)(1)(i)(B) of this AD.
(A) Prior to the accumulation of 40,000 total flight cycles or 60,000 total flight hours, whichever occurs first.
(B) Within 250 flight hours after the effective date of this AD.
(ii) For Model A310-304 airplanes: Inspect at the later of the times specified in paragraphs (f)(1)(ii)(A) and (f)(1)(ii)(B) of this AD.
(A) Prior to the accumulation of 35,000 total flight cycles or 60,000 total flight hours, whichever occurs first.
(B) Within 250 flight hours after the effective date of this AD.
(2) If no crack is found during any inspection required by paragraph (f)(1) of this AD: Repeat the inspections thereafter at intervals not to exceed 15,000 flight hours.
(3) If any crack is found during any inspection required by paragraph (f)(1) of this AD: Before further flight, modify Rib 5 in the pylon box in accordance with the Accomplishment Instructions of Airbus Service Bulletins A310-54-2032, Revision 01, dated October 8, 2007. Accomplishment of this modification ends the repetitive inspections required by this AD.
(4) Accomplishment of the HFEC and detailed visual inspections before the effective date of this AD in accordance with Airbus Service Bulletin A310-54-2036, Revision 01, dated September 14, 1999, meets the corresponding requirements of paragraph (f) of this AD.
(5) Accomplishment of the modification before the effective date of this AD in accordance with Airbus Service Bulletin A310-54-2032, dated May 29, 1996, meets the corresponding requirements of paragraph (f) of this AD.
(6) Submit the initial inspection results specified in Appendix 01 of Airbus Mandatory Service Bulletin A310-54-2036, Revision 02, dated September 28, 2007, at the time specified in paragraph (f)(6)(i) or (f)(6)(ii) of this AD.
(i) If the inspections were done after the effective date of this AD: Within 30 days after accomplishing the inspections required by paragraph (f)(1) of this AD.
(ii) If the inspections were done prior to the effective date of this AD: Within 30 days after the effective date of this AD.
Note: This AD differs from the MCAI and/or service information as follows: Although the MCAI allows further flight after cracks are found during compliance with the required action, this AD requires that you repair the crack(s) before further flight.
