ACTION: Notice of proposed rulemaking (NPRM). SUMMARY: The FAA proposes to supersede Airworthiness Directive (AD) 2021-17-07, which applies to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2021-17-07 requires inspecting for damage of the left and right motive flow (MF) flexible fuel line assemblies (including the flexible hose and shroud assemblies), and replacing damaged parts. Since the FAA issued AD 2021-17-07, the FAA has determined that four additional airplanes may be subject to the unsafe condition. This proposed AD would continue to require the actions in AD 2021-17-07 and expand the applicability. The FAA is proposing this AD to address the unsafe condition on these products. DATES: The FAA must receive comments on this proposed AD by October 19, 2026.
