## Discrepancy

THE NR 2 ENGINE OIL QUANTITY DROPPED FROM ABOUT 13 QUARTS TO 6.5 QUARTS AFTER 1.5 HOURS OF FLIGHT.  MAINTENANCE FOUND THE NR 2 ENGINE LEAKING OIL FROM FUEL PUMP DRIVE PAD.  THE FUEL PUMP AND FUEL CONTROL ASSEMBLY WERE REMOVED AND THE GEARBOX CARBON SEAL WAS REPLACED.  THE FUEL PUMP AND FUEL CONTROL ASSEMBLY WERE REINSTALLED IAW MM 73-10-1.  THE ENGINE WAS RUN AND LEAK CHECKS WERE GOOD.
