Airworthiness Directive · Amendment 39-17306 · Electrical power system wiring
Bell Helicopter Textron Inc. Helicopters
This AD applies to Bell Helicopter Textron Inc. (BHTI) Model 205A, 205A-1, and 205B helicopters with starter/generator power cable assemblies (power cable assemblies), part number (P/N) 205-075-902-017 and P/N 205-075-911-007 installed, certificated in any category.
We are adopting a new airworthiness directive (AD) for the Bell Helicopter Textron Inc. (BHTI) Model 205A, 205A-1, and 205B helicopters with certain starter/generator power cable assemblies (power cable assemblies). This AD requires replacing the power cable assemblies and their associated parts, and performing continuity readings. This AD was prompted by the determination that the power cable assembly connector (connector) can deteriorate, causing a short in the connector that may lead to a fire in the starter/generator, smoke in the cockpit that reduces visibility, and subsequent loss of helicopter control.
You are responsible for performing each action required by this AD within the specified compliance time unless accomplished previously.
Within six months, replace the power cable assemblies using the parts contained in starter/generator kit P/N CT205-07-94-1, perform a continuity test, and connect wires to the starter generator as follows:
(1) For Model 205A and 205A-1 helicopters, follow the Accomplishment Instructions, paragraphs 2 through 16(c), of BHTI Alert Service Bulletin No. 205-07-94, Revision A, dated December 8, 2008.
(2) For the Model 205B helicopters, follow the Accomplishment Instructions, paragraphs 2 through 16(c), of BHTI Alert Service Bulletin No. 205B-08-50, dated December 8, 2008.
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.
