## Discrepancy

(CAN) DURING REVENUE FLIGHT, THE ENGINE OIL PRESSURE DROPPED TO 0 FOLLOWED BY A DECREASE OF PROPELLER SPEED AND AN INCREASE OF TORQUE INDICATION.  AROUND 30 SECONDS AFTER LOSS OF OIL PRESSURE THERE WAS AN UN-COMMANDED ENGINE SHUTDOWN. THE ACFT LANDED UNEVENTFULLY WITH A SINGLE ENGINE RUNNING. THE ENGINE WILL BE REMOVED FOR INVESTIGATION.
