AD Issued for Bell 505 Wire Harness Inspection
The FAA has issued airworthiness directive (AD) 2025-09-01 for certain serial-numbered Bell Textron Canada Limited Model 505 helicopters. This AD was prompted by reports of possible chafing in certain locations between the basic and supplemental helicopter wiring and the structure. This AD requires repetitively inspecting the wire harnesses at certain locations for damage, and if any wire damage is found, repairing the damaged wire/bundles, as specified in Transport Canada AD CF-2024-44, dated December 19, 2024.
