Airworthiness Directive · Amendment 39-11196 · Bell Helicopter Textron Canada (BHTC) Model 206L-4 Helicopters
Bell Helicopter Textron Canada (BHTC) Model 206L-4 Helicopters
Model 206L-4 helicopters, certificated in any category.
This amendment adopts a new airworthiness directive (AD) that is applicable to BHTC Model 206L-4 helicopters. This action requires a reduction in the retirement lives of certain collective idler links and collective levers, and re-identifying certain collective idler links and collective levers. This amendment is prompted by the discovery of two types of collective idler links and collective levers--manufactured from different materials--that are identified with the same part numbers but should have substantially different retirement lives. The actions specified in this AD are intended to prevent use of a collective idler link (link) or collective lever (lever) beyond its retirement life, which could lead to failure of the link or lever 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.
