## Discrepancy

(CAN) 16 MINUTES INTO THE FLIGHT, THE CREW NOTICED A SLIGHT YAW OF THE ACFT, FOLLOWED BY AN UNUSUAL PROPELLER SOUND ON THE NR 2 ENGINE.  TORQUE WAS INDICATING APPROXIMATELY 104.1 PERCENT AND RPM WAS INDICATING 500-540 RPM.  THE CREW CALLED AN UNCOMMANDED AUTOFEATHER AND THE ENGINE SHUTDOWN.  A SAFE SINGLE ENGINE LANDING FOLLOWED.  TROUBLESHOOTING FOUND A MAGNETIZED TORQUE SHAFT.
