## Discrepancy

NR 1 ENGINE HAD INFLIGHT SHUTDOWN DUE TO LOSS OF OIL QUANTITY AND DECREASE IN OIL PRESSURE.  AFTER SHUTDOWN ENGINE WINDMILLED FOR 35 MINUTES, OIL TEMPERATURE 110-115, OIL PRESSURE 9.5 PSI AND OIL QUANTITY ZERO.  INTERFACE BETWEEN FUEL PUMP AND MAIN ENGINE GEARBOX WAS FOUND TO BE LEAKING OIL.  CARBON SEAL WAS REPLACED AND NO FURTHER LEAKS WERE OBSERVED DURING ENGINE GROUND RUN.
