Airworthiness Directive · Amendment 39-12868 · Bell Helicopter Textron, a Division of Textron Canada, Model 407 Helicopters
Bell Helicopter Textron, a Division of Textron Canada, Model 407 Helicopters
Model 407 helicopters, with serial numbers less than 53480, certificated in any category.
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron, A Division of Textron Canada (BHT), Model 407 helicopters. This action requires a fuel filler cap assembly shimming and electrical bonding procedure. This amendment is prompted by the FAA's determination, based on information from the manufacturer, that electrical bonding may be inadequate. The actions specified in this AD are intended to prevent a lack of electrical bonding that could result in an electrical arc, ignition of fuel vapors, and an onboard fire.
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.
