## Discrepancy

(CAN) WHILE EN-ROUTE, THE CREW NOTICED A NR 2 ENGINE OIL PRESSURE FLUCTUATION. THEY ELECTED TO SHUTDOWN THE ENGINE AND RETURN TO DEPARTURE AIRPORT WHERE THEY LANDED SAFELY.  POST FLIGHT INSPECTION FOUND OIL LEAKING FROM THE REDUCTION GEARBOX AT THE HYD PUMP DRIVE PAD DUE TO A FAULTY OIL SEAL, WHICH WAS REPLACED BEFORE THE ACFT WAS RETURNED TO SERVICE.
