Airworthiness Directive · Amendment 39-23005 · Standard practices/structures
Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes
Superseded. A later AD replaced this one: AD 2025-11-06. Comply with the one in force.
This AD applies to all Airbus Canada Limited Partnership (Type Certificate previously held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Model BD-500-1A11 airplanes, certificated in any category.
The FAA is adopting a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A11 airplanes. This AD was prompted by a design review of aircraft structural and stress reports that resulted in a revision of operational loads for some aircraft flight phases. This AD requires a review and disposition of all existing repairs and damage assessments for affected structure, corrective actions if necessary, and the prohibition of certain repair engineering orders (REOs), 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-2023-70, dated October 5, 2023 (Transport Canada AD CF-2023-70).
(1) Where Transport Canada AD CF-2023-70 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where the definition of “Affected Structure” in Transport Canada AD CF-2023-70 specifies “as identified in Service Bulletin (SB) BD500-530012, Issue 001, dated 13 September 2023 or later revisions approved by the Chief, Continuing Airworthiness, Transport Canada,” this AD requires replacing that text with “as identified in Airbus Canada Limited Partnership Service Bulletin BD500-530012, Issue 001, dated September 13, 2023; or Airbus Canada Limited Partnership Service Bulletin BD500-530012, Issue 002, dated March 6, 2024.”
(3) Where paragraph 1.2.1 of Airbus Canada Limited Partnership Service Bulletin BD500-530012, Issue 001, dated September 13, 2023, specifies “Airbus Canada specific Repair Engineering Order (REO) with an issue date later than December 31, 2022 have already been validated and therefore do not require an additional approved disposition;” and where paragraph 1.2.1 of Airbus Canada Limited Partnership Service Bulletin BD500-530012, Issue 002, dated March 6, 2024, specifies “Airbus Canada specific Repair Engineering Orders (REO) with an issue date later than December 31, 2022 have already been validated and therefore do not require an additional approved disposition;” this AD requires replacing that text with “Airbus Canada specific Repair Engineering Orders (REOs) with an issue date later than December 31, 2022, and Generic Repair Engineering Orders (GREOs) identified in table 1 to paragraph (h)(3) of AD 2025-07-04, have already been validated and therefore do not require an additional approved disposition.”
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 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.
