Airworthiness Directive · Amendment 39-12598 · Bell Helicopter Textron Canada Model 430 Helicopters
Bell Helicopter Textron Canada Model 430 Helicopters
Model 430 helicopters, serial numbers 49002 through 49071, certificated in any category.
This amendment adopts a new airworthiness directive (AD) for Bell Helicopter Textron Canada (BHTC) Model 430 helicopters that requires changes to the electrical power distribution system. This amendment is prompted by design deficiencies in the electrical systems. The actions specified by this AD are intended to prevent failure of both generators, loss of primary electrical power, and subsequent loss of control of the helicopter.
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.
