Airworthiness Directive · Amendment 39-22898 · Equipment/furnishings
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-2023-40, dated June 13, 2023 (Transport Canada AD CF-2023-40).
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 multiple occurrences of pilot and co-pilot seats locking in a fore-aft position due to the seat fore- aft adjustment mechanism disconnecting, caused by a broken cotter pin in the seat base egress linkage. This AD requires modifying the pilot and co-pilot seats by replacing the hardware of the seat base egress linkage, 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-2023-40.
(1) Where Transport Canada AD CF-2023-40 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2023-40 refers to “hours air time,” this AD requires using flight hours.
(3) Where the service information referenced in Transport Canada AD CF-2023-40 specifies to “Do Goodrich Interiors Service Bulletin 1430-25-003,” this AD requires replacing that text with “Do Goodrich Interiors Service Bulletin 1430-25-003, Revision C, dated November 22, 2022.”
(4) Where the service information specified in Transport Canada AD CF-2023-40 specifies removal and installation steps in accordance with both Airbus Canada Limited Partnership Service Bulletin BD500-251006 and Goodrich Interiors Service Bulletin 1430-25-003, this AD does not require the removal/installation steps in Goodrich Interiors Service Bulletin 1430-25-003.
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 manager of the International Validation Branch, mail it to the address identified in paragraph (j) of this AD. Information may be emailed 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, International Validation Branch, FAA; or Transport Canada; or 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 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.
