Airworthiness Directive · Amendment 39-14929 · Airbus Model A300 and A300-600 Airplanes
Airbus Model A300 and A300-600 Airplanes
Superseded. A later AD replaced this one: AD 2015-02-24. Comply with the one in force.
This AD applies to Airbus Model A300 and A300-600 airplanes; certificated in any category, all certified models, all serial numbers except for those where LH (left-hand) and RH (right-hand) wing MLG (main landing gear) rib 5 forward lugs have been repaired by installation of oversized interference fit bushings as per drawing R57240221.
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 in the wing main landing gear (MLG) rib 5 aft bearing forward lug, which could affect the 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 specified in paragraphs (e)(1), (e)(2), and (e)(3) of this AD in accordance with instructions defined in Airbus Service Bulletin A300-57A6105, dated December 12, 2006; or A300-57A0248, dated December 12, 2006; as applicable.
(1) Before the accumulation of 12,000 total flight cycles since new or since the most recent MLG rib 5 replacement if applicable, or within 10 days after the effective date of this AD, whichever occurs latest: Perform a detailed visual inspection of the LH and RH wing MLG rib 5 aft bearing forward lugs.
(2) If a crack is detected at the LH and/or RH aft bearing forward lug, contact Airbus immediately and proceed with the replacement before further flight.
(3) Repeat the inspection at intervals not to exceed 100 flight cycles.
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.
