## Discrepancy

(CAN) DURING CRUISE, THE ENGINE HAD AN UNCOMMANDED POWER CHANGE ACCOMPANIED WITH ACFT YAW.  THE ENGINE WAS SHUTDOWN AND THE CREW ATTEMPTED A RESTART BUT THE ENGINE REMAINED AT IDLE, AND AS SUCH IT WAS SHUTDOWN AGAIN.  AN UNEVENTFUL SINGLE ENGINE FOLLOWED.  POST FLIGHT TROUBLESHOOTING FOUND A FAULTY TORQUE PROBE WHICH WAS REPLACED BEFORE THE ACFT WAS RETURNED TO SERVICE.  MFG RECOMMENDS THE SDR BE CLOSED ON THE BASIS OF THE FOLLOWING INFORMATION.
