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 reports that the pylon-to-wing area motive flow flexible fuel line assemblies may have been installed incorrectly. This AD requires inspecting the motive flow fuel line assemblies and performing 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-2023-64.
(1) Where Transport Canada AD CF-2023-64 refers to its effective date, this AD requires using the effective date of this AD.
(2) Where Transport Canada AD CF-2023-64 refers to hours air time, this AD requires using flight hours.
(3) Where the Corrective Actions paragraph of Transport Canada AD CF-2023-64 specifies to “Inspect and, if necessary, replace the left and right motive flow fuel line assemblies,” for this AD, replace that text with “Inspect and, as applicable, replace the left and right motive flow fuel line assemblies.”
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.

If sending information directly to the manager of the International Validation Branch, mail it to the address identified in paragraph (j) of this AD.

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.
