## Discrepancy

(CAN) AIRCRAFT EXPERIENCED AN INFLIGHT POWER LOSS ON THE NR 2 ENGINE WHILE ON ROUTE, AND DIVERTED TO ALTERNATE. THE FLIGHT CREW HEARD AN ABNORMAL NOISE FROM THE ENGINE, ACCOMPANIED BY A YAW AND LOSS OF TORQUE. THE ENGINE WAS SHUT DOWN AND FEATHERED, AND THE AIRCRAFT LANDED WITHOUT INCIDENT. INITIAL INSPECTION BY MAINTENANCE INDICATES A POTENTIAL ISSUE IN THE POWER TURBINE SECTION INTERNALLY IN THE ENGINE, BUT UNCONFIRMED AT THIS POINT UNTIL WE INVESTIGATE FURTHER. A MAINTENANCE CREW AND REPLACEMENT ENGINE IS COMPLETING THE NECESSARY REPAIRS.
