## Discrepancy

THE NR 1 ENGINE LOW OIL PRESSURE WARNING ILLUMINATED ON TAKEOFF.  TAKEOFF WAS ABORTED, THE AIRCRAFT RETURNED TO THE GATE.  MAINTENANCE REPLACED THE LOW OIL PRESSURE AND DIFFERENTIAL PRESSURE SWITCHES.  THE MAIN OIL FILTER WAS INSPECTED FOR CONTAMINANTS, NONE FOUND.  SYSTEM OPERATION CHECKED OK ON RUNUP.  THE AIRCRAFT RETURNED TO SERVICE.
