## Discrepancy

(CAN) THE NR 2 ENGINE OIL PRESSURE DROPPED BELOW 80 PSI ON FLIGHT.  THE POWER WAS REDUCED AND THE AIRCRAFT LANDED.  POST-FLIGHT INSPECTION FOUND OIL ON THE ENGINE COWLING.  IT WAS DETERMINED THAT THE OIL WAS LEAKING FROM THE FUEL PUMP DRAIN.  THE NR 2 ENGINE FUEL PUMP DRIVE SEAL WAS FOUND DEFECTIVE.  A NEW SEAL WAS INSTALLED AND THE OIL LEVEL REPLENISHED.  AN ENGINE GROUND RUN WAS CARRIED OUT AND THERE WERE NO LEAKS.
