This AD applies to the following airplanes:
(1) Airbus Model A330-200 and A330-300 series airplanes, all certified models, certificated in any category, all serial numbers; except those on which Airbus modification 49353 has been embodied in production, or Airbus Service Bulletin A330-57-3082 has been embodied in service on both wings; and except those that have been repaired on both wings as per Airbus UK Limited Repair Drawing R572-56230, or Airbus A330 Structural Repair Manual 57-26-13, page block 201.
(2) Airbus Model A340-200 and A340-300 series airplanes, all certified models, certificated in any category, all serial numbers; except those on which Airbus modification 49353 has been embodied in production, or Airbus Service Bulletin A340-57-4088 has been embodied in service on both wings; and except those that have been repaired on both wings as per Airbus UK Limited Repair Drawing R572-56230, or Airbus A340 Structural Repair Manual 57-26-13, page block 201.
(3) Airbus Model A340-500 and A340-600 series airplanes, all certified models, certificated in any category, all serial numbers; except those on which Airbus modification 50040 or 51585 has been embodied in production.
We are adopting a new airworthiness directive (AD) for the products listed above. This AD results from mandatory continuing airworthiness information (MCAI) issued 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 cracking of the wing MLG (main landing gear) rib 6 aft bearing forward lugs, which could result in reduced structural integrity of the MLG attachment. This AD requires actions that are intended to address the unsafe condition described in the MCAI.
Unless already done, do the following actions in accordance with the instructions defined in Airbus Service Bulletin A330-57A3096, dated December 5, 2006; A340-57A4104, dated December 5, 2006; or A340-57A5009, dated December 5, 2006; as applicable.
(1) Within 60 months since first flight, or 14 days after the effective date of this AD, whichever occurs later: Perform a detailed visual inspection of the LH (left-hand) and RH (right-hand) wing MLG rib 6 aft bearing lugs (forward and aft) to detect any cracks on the two lugs.
(2) If any crack is detected, contact Airbus immediately and proceed with the replacement of the MLG rib 6 before further flight.
(3) If no crack is detected, repeat the inspection at intervals not to exceed the applicable interval specified in paragraph (e)(3)(i), (e)(3)(ii), or (e)(3)(iii) of this AD, and if a crack is detected during the repeat inspections, before further flight, apply the corrective action mentioned in paragraph (e)(2) of this AD as applicable.
(i) 300 flight cycles (FC) for Model A330 airplanes.
(ii) 200 FC for Model A340-200 and A340-300 airplanes.
(iii) 100 FC for Model A340-500 and A340-600 airplanes.
Note: This AD differs from the MCAI and/ or service information as follows: No differences.
