Airworthiness Directive · Amendment 39-23482 · Wings
Bombardier, Inc., Airplanes
This AD applies to Bombardier, Inc., Model BD-700-2A12 airplanes, certificated in any category, as identified in Transport Canada AD CF-2025-49, dated October 1, 2025 (Transport Canada AD CF-2025-49).
The FAA is adopting a new airworthiness directive (AD) for certain Bombardier, Inc., Model BD-700-2A12 airplanes. This AD was prompted by reports of low clearance in the right wing between the fuel line flexible coupling and the harness support bracket clip-nut, between the fuel line flexible coupling and hydraulic system, and between the hydraulic system and fuel vent tube. This AD requires rectifying the low clearance condition between the fuel line flexible coupling and the harness support bracket clip-nut, rectifying the low clearance condition between the fuel line flexible coupling and the hydraulic system, and doing an inspection for adequate clearance between the hydraulic system and the fuel vent tube and applicable on-conditions actions. The FAA is issuing this AD to address the unsafe condition on these products.
Except as specified in paragraphs (h) and (i) of this AD: Comply with all required actions and compliance times specified in, and in accordance with, Transport Canada AD CF-2025-49.
(1) Where Transport Canada AD CF-2025-49 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2025-49 refers to hours air time, this AD requires using flight hours.
Although the material referenced in Transport Canada AD CF-2025-49 specifies to submit certain information to the manufacturer, this AD does not include that requirement.
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, send it to the attention of the person identified in paragraph (k) 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, International Validation Branch, FAA; or Transport Canada; or Bombardier, Inc.'s Transport Canada Design Approval Organization (DAO). If approved by the DAO, the approval must include the DAO-authorized signature.
