## Discrepancy

(CAN) DURING CRUISE, OIL PRESSURE WAS LOST ON THE COMBINING GEARBOX AND THE PILOT PERFORMED AN UNSCHEDULED LANDING OFF BASE.  THE HELO HAD TO BE TRANSPORTED BACK ON A TRUCK.  INSPECTION OF THE ENGINE REVEALED A CRACK IN THE GEARBOX HOUSING FROM WHICH THE OIL ESCAPED.  THE GEARBOX WILL BE REMOVED AND FORWARDED TO P&WC FOR INVESTIGATION.  UPDATES WILL BE PROVIDED IN DUE COURSE.
