Abstract
The FAA is adopting a new airworthiness directive (AD) for certain Airbus Canada Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by the potential for the flexible hose assembly of the fuel motive flow (MF), installed between the pylon and wing, to be installed twisted in the shroud, which can restrict the flow of fuel for the MF and cause fuel imbalance and damage to the shroud assembly. This AD requires inspecting for damage of the left and right MF fuel line assemblies (including the flexible-hose and shroud assemblies), and replacing damaged parts, as specified in a Transport Canada Civil Aviation (TCCA) AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
