## Abstract

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.
