## Discrepancy

FLIGHT CREW REPORTED A LOSS OF THE NR 1 ENGINE OIL PRESSURE DURING CLIMBOUT,  ACCOMPANIED BY AN AMBER EXCEEDENCE MESSAGE,  FOLLOWED BY A RED EXCEEDENCE MESSAGE.  NO RED WARNING PANEL OIL PRESSURE WARNING OBSERVED.  FLIGHT CREW SECURED THE ENGINE IAW QRH PROCEDURES AND RETURNED TO DEPARTURE.
