This amendment adopts a new airworthiness directive (AD), applicable to certain Canadair Model CL-600-1A11, -2A12, and -2B16 series airplanes, that requires a functional check and a test of the idle stop function of the engine throttle quadrant; repair or replacement, if necessary; and eventual replacement of the engine throttle quadrant with a new model. This amendment is prompted by reports of unintentional engine shutdown on certain of these airplanes due to problems associated with operation of the engine throttle quadrant. The actions specified by this AD are intended to ensure the proper operation of the throttle quadrant so as to prevent inadvertent shutdown of an engine while the airplane is taxiing or in flight.
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.
