## Discrepancy

(CAN) DURING CRUISE FLIGHT, THE FLIGHT CREW NOTICED A MOMENTARY FLUCTUATION AND THEN DECREASING OIL PRESSURE, THEN EVERYTHING RETURNED TO NORMAL.   MOMENTS LATER, THE ENGINE FAILED AND THE CREW CARRIED OUT THE SHUTDOWN. THE AIRCRAFT LANDED WITHOUT INCIDENT, ONCE ON THE GROUND, THE FLIGHT CREW ATTEMPTED TO TURN THE PROPELLER AND FOUND IT WAS SEIZED. MAINTENANCE ARRIVED AND CONFIRMED A CATASTROPHIC FAILURE OF THE POWER SECTION GEAR BOX. (TC NR 20070515007)
