Airworthiness Directive · Amendment 39-15980 · Landing gear
Airbus Model A330-200, A330-300, A340-200, and A340-300 Series Airplanes
Superseded. A later AD replaced this one: AD 2016-18-07. Comply with the one in force.
This AD applies to Airbus Model A330-200, A330-300, A340-200, and A340-300 series airplanes; certificated in any category; all certified models; all serial numbers, except those on which Airbus modification 54500 has been embodied in production or Airbus Service Bulletin A330-32-3212 has been embodied in service.
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: * * * * * [B]ogie beam internal paint has been degraded, leading to a loss of cadmium plating and thus allowing development of corrosion pitting. If not corrected, this situation under higher speed could result in the aircraft departing the runway or in the bogie [beam] detaching from the aircraft or [main landing] gear collapses, which would constitute an unsafe condition. * * * * * We are issuing this AD to require actions to correct the unsafe condition on these products.
Unless already done, do the following actions.
(1) At the applicable compliance time specified in paragraph (f)(2) or (f)(3) of this AD: Clean the internal bore and perform a detailed visual inspection of internal surfaces of the MLG bogie beam (right-hand and left-hand) for any damage to the protective treatments or any corrosion, in accordance with the Accomplishment Instructions of Airbus Mandatory Service Bulletin A330-32-3225 or A340-32-4268, both Revision 01, both dated October 30, 2008; as applicable.
(i) If no damage and corrosion is found, before further flight, apply the protective treatments of the bogie beam, in accordance with the Accomplishment Instructions of Messier-Dowty Service Bulletin A33/34-32-272, Revision 1, including Appendixes A, B, C, and D, dated September 22, 2008.
(ii) If any damage or corrosion is found, before further flight, do all applicable corrective actions and apply the protective treatments of the bogie beam, in accordance with the Accomplishment Instructions of Messier-Dowty Service Bulletin A33/34-32-272, Revision 1, including Appendixes A, B, C, and D, dated September 22, 2008.
