Airworthiness Directive · Amendment 39-23344 · Bell Textron Canada Limited Helicopters
Bell Textron Canada Limited Helicopters
This AD applies to Bell Textron Canada Limited 407.
The models as the FAA's AD index lists them. The serial ranges, installed parts and exceptions are in the AD itself: read it at the FAA.
The FAA is adopting a new airworthiness directive (AD) for certain Bell Textron Canada Limited (BTCL) Model 407 helicopters. This AD was prompted by a determination that chafing can occur at various locations on the electrical harnesses located in the aircraft instrument panel area. This AD requires a one-time detailed visual inspection of the electrical harnesses for chafing and corrective actions if necessary. This AD also requires rotation of the backshell cast housing of connectors of the lower engine airframe unit and installation of a wire harness bracket and support, and for certain helicopters, installation of a wire bundle sleeve. The FAA is issuing this AD to address the unsafe condition on these products.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
