Full official abstract

This amendment adopts a new airworthiness directive (AD), applicable to Bell Helicopter Textron, a Division of Textron Canada, Ltd. (BHTC) Model 206L-1 helicopters that have a Kratos turbine outlet temperature (TOT) indicator (Kratos indicator) installed, that requires replacing certain Kratos indicators. This amendment is prompted by manufacturer's tests and FAA analyses that show certain Kratos indicators may incorrectly provide low-temperature readings when the battery voltage is below 10 volts. The actions specified by this AD are intended to prevent false low-temperature indications, which could result in overheating of the engine turbine (turbine) and subsequent thermal fatigue damage to the turbine wheel.
