## Abstract

The FAA is superseding Airworthiness Directive (AD) 2024-04- 11, which applied to certain Airbus Canada Limited Partnership Model BD-500-1A10 and BD-500-1A11 airplanes. AD 2024-04-11 required modifying the variable frequency generator (VFG) power-feeder harness routing. Since the FAA issued AD 2024-04-11, the FAA received a report of damage to a VFG power-feeder harness, resulting in the loss of the associated VFG and the posting of the L GEN FAIL (Caution) message. This AD continues to require modifying the VFG power-feeder harness routing, and also requires inspecting the VFG power-feeder harnesses for damage and clearance, repairing or replacing the VFG power-feeder harnesses if necessary, modifying and adjusting the VFG power-feeder harnesses if necessary, and prohibiting dispatch of certain airplanes under certain master minimum equipment list (MMEL) items; as specified in a Transport Canada emergency AD, which is incorporated by reference. The FAA is issuing this AD to address the unsafe condition on these products.
