## Discrepancy

(CAN) DURING CRUISE, THE NR 1 ENGINE OIL PRESSURE FLUCTUATED 50-60 PSI.  LOW OIL PRESSURE CAUTION LIGHT INTERMITTENT.  POWER REDUCED.  LANDING NORMAL.  INSPECTION FOUND LOW OIL QUANTITY DUE TO A LARGE LEAK FROM OIL COOLER INLET FITTING.  THE COOLER RIGID LINE HAD CHAFED THE FITTING ALLOWING OIL TO LEAK PAST THE PACKING.  P/N AS3209-219.  LINE WAS BELIEVED TO HAVE BEEN COCKED AT INSTALLATION.
