Airworthiness Directive · Amendment 39-23054 · Landing gear
Airbus SAS Airplanes
This AD applies to all Airbus SAS Model A350-941 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus SAS Model A350-941 airplanes. This AD was prompted by an inspection that found several anodic burns on the main landing gear (MLG) bogie beam axles following a high velocity oxygen-fuel (HVOF) stripping process. This AD requires replacement of affected MLG bogie beam axles and prohibits the installation of affected parts. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraph (h) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, European Union Aviation Safety Agency (EASA) AD 2024-0156, dated August 13, 2024 (EASA AD 2024-0156).
(1) Where EASA AD 2024-0156 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where EASA AD 2024-0156 defines a serviceable part as “Any MLG bogie beam axle, eligible for installation in accordance with Airbus instructions, that is not an affected part”, for this AD replace that text with “Any MLG bogie beam axle, eligible for installation, that is not an affected part”.
(3) Where paragraph (1) of EASA AD 2024-0156 specifies a compliance time for the replacement, for this AD, do the replacement within 24,000 flight hours or 5,700 flight cycles, whichever occurs first since first installation of the affected part on an airplane, or within 12 months after the effective date of this AD, whichever occurs later.
(4) Where paragraph (1) of EASA AD 2024-0156 specifies “in accordance with the instructions of the SB”, this AD requires replacing that text with “in accordance with the replacement instructions of the SB”.
(5) This AD does not adopt the “Remarks” section of EASA AD 2024-0156.
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, AIR-520, Continued Operational Safety Branch, FAA, has the authority to approve AMOCs for this AD, if requested using the procedures found in 14 CFR 39.19. In accordance with 14 CFR 39.19, send your request to your principal inspector or responsible Flight Standards Office, as appropriate. If sending information directly to the manager of AIR-520, Continued Operational Safety Branch, send it to the attention of the person identified in paragraph (j) of this AD and email to: AMOC@faa.gov. Before using any approved AMOC, notify your appropriate principal inspector, or lacking a principal inspector, the manager of the responsible Flight Standards Office.
(2) Contacting the Manufacturer: For any requirement in this AD to obtain instructions from a manufacturer, the instructions must be accomplished using a method approved by the Manager, AIR-520, Continued Operational Safety Branch, FAA; or EASA; or Airbus SAS's EASA Design Organization Approval (DOA). If approved by the DOA, the approval must include the DOA-authorized signature.
(3) Required for Compliance (RC): Except as required by paragraph (i)(2) of this AD, if any material contains procedures or tests that are identified as RC, those procedures and tests must be done to comply with this AD; any procedures or tests that are not identified as RC are recommended. Those procedures and tests that are not identified as RC may be deviated from using accepted methods in accordance with the operator's maintenance or inspection program without obtaining approval of an AMOC, provided the procedures and tests identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures or tests identified as RC require approval of an AMOC.
