The FAA amends § 39.13 by adding the following new airworthiness directive: 2025-09-01 Bell Textron Canada Limited: Amendment 39-23022; Docket No. FAA-2025-0740; Project Identifier MCAI-2024-00775-R.

The FAA is issuing this AD to prevent fouling in the helicopter wiring and the structure. The unsafe condition, if not addressed, could result in a short to ground, which would command the engine to idle and could lead to loss of control of the helicopter.
