Airworthiness Directives; Airbus Canada Limited Partnership (Type Certificate Previously Held by C Series Aircraft Limited Partnership (CSALP); Bombardier, Inc.) Airplanes

FAA / Federal Register · 2023-19861

The FAA proposes to adopt a new airworthiness directive (AD) for certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD- 500-1A11 airplanes. This proposed AD was prompted by damage found on two power-feeder harnesses due to chafing with wheel bins. An investigation found that the power-feeder harnesses were not adequately supported to protect from chafing due to vibration. This proposed AD would require modifying the variable frequency generator (VFG) power- feeder harness routing, as specified in a Transport Canada AD, which is proposed for incorporation by reference (IBR). The FAA is proposing this AD to address the unsafe condition on these products.
