Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
This AD applies to Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A10 and BD-500-1A11 airplanes, certificated in any category, as identified in Transport Canada AD CF-2023-20, dated March 22, 2023 (Transport Canada AD CF-2023-20).
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500- 1A11 airplanes. This AD was prompted by a report of multiple occurrences of low clearance or fouling between certain wiring harnesses and a hydraulic bracket and structure in the wing trailing edge area that were detected on the production line. This AD requires inspecting certain wiring harnesses for any damage and clearance to adjacent structure and corrective actions, as specified in a Transport Canada AD, which is incorporated by reference. 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, Transport Canada AD CF-2023-20.
(1) Where Transport Canada AD CF-2023-20 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2023-20 refers to hours air time, this AD requires using flight hours.
(3) Where paragraph A. of Transport Canada AD CF-2023-20 states to “adjust as required,” this AD requires that all applicable adjustments must be done before further flight.
(4) Where Transport Canada AD CF-2023-20 specifies actions using Airbus Canada Service Bulletin BD500-240012, Issue 003, dated March 17, 2023, this AD requires adding the information in figure 1 to paragraph (h)(4) of this AD to paragraph A. of Transport Canada AD CF-2023-20.
(5) Where paragraph A. of Transport Canada AD CF-2023-20 specifies “Airbus Canada Service Bulletin (SB) BD500-240012, Issue 003, dated 17 March 2023,” this AD requires replacing that text with “Airbus Canada Service Bulletin (SB) BD500-240012, Issue 003, dated 17 March 2023, or later revision approved by Transport Canada.”
The following provisions also apply to this AD:
(1) Alternative Methods of Compliance (AMOCs): The Manager, International Validation 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 International Validation Branch, send it to the attention of the person identified in paragraph (j) of this AD. Information may be emailed to: 9-AVS-AIR-730-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, International Validation Branch, FAA; or Transport Canada; or Airbus Canada Limited Partnership's Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
(3) Required for Compliance (RC): Except as required by paragraph (i)(2) of this AD, if any service information contains procedures that are identified as RC, those procedures must be done to comply with this AD; any procedures that are not identified as RC are recommended. Those procedures 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 identified as RC can be done and the airplane can be put back in an airworthy condition. Any substitutions or changes to procedures identified as RC require approval of an AMOC.
