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

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 damage found on two power- feeder harnesses on three airplanes 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 AD requires modifying the variable frequency generator (VFG) power-feeder harness routing, 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.
