What the FAA requires

The FAA is adopting a new airworthiness directive (AD) for all Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. This AD was prompted by certification testing that found that environmental control system (ECS) ducts manufactured using a certain material failed the flammability test requirements established for compliance. This AD requires inspecting the affected ECS ducts, installing a fire-resistant sleeve assembly over any non-compliant ECS duct as applicable, and re-identifying the ceiling panel liners. This AD also prohibits the installation of ECS ducts as replacement parts under certain conditions. The FAA is issuing this AD to address the unsafe condition on these products.
