## Discrepancy

DURING RETURN FLIGHT FROM MWCR TO KHOU, THE NR 1 ENGINE OIL PRESSURE BEGAN TO FLUCTUATE AND DROP.  THE FLIGHT CREW OBSERVED THIS AND REDUCED POWER TO FLIGHT IDLE.  THE NR 1 ENGINE OIL PRESSURE DROPPED BELOW 5 PSI, ILLUMINATING THE LOW OIL PRESSURE LIGHT.  AT THIS POINT, THE FLIGHT CREW ELECTED TO SHUT DOWN THE NR 1 ENGINE AND CONTINUE TO KHOU.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  UPON INVESTIGATION, THE OIL LINE PACKING WAS FOUND TO BE LEAKING AT THE FUEL HEATER.  THE ENGINE OIL WAS LEVEL WAS THREE QUARTS LOW.  THE ENGINE OIL WAS SERVICED TO FULL AND THE FUEL HEATER WAS RESEALED WITH NEW PACKINGS.  THE REPLACEMENT PACKING FOR THE LEAKING CONNECTION WAS P/N: S9413-565.
