## Discrepancy

WHILE EN ROUTE BETWEEN CVG AND PIT, THE CAPTAIN NOTICED A DROP FROM 65 PSI TO 50 PSI IN THE LEFT POEWR SECTION OIL PRESSURE, FLUCTUATING REDUCTION GEARBOX OIL PRESSURE AND A THREE GALLON DROP IN OIL QTY.  THE CAPTAIN PULLED THE LEFT 'E' HANDLE AND SECURED THE ENGINE.  THE CREW DIVERTED TO THE COLUMBUS MAINTENANCE FACILITY AT LCK.  A BROKEN EXTERNAL OIL PRESSURE LINE SERVICING THE NR 4 BEARING WAS REPLACED AND THE AIRCRAFT WAS RETURNED TO SERVICE.  THE FAILURE OF THE OIL LINE MAY HAVE BEEN CAUSED BY A VIBRATING REDUCTION GEARBOX THAT HAD RECENTLY BEEN REPLACED ON THAT ENGINE.  (M)
