## Discrepancy

NR 1 ENGINE OIL QUANTITY WAS DECREASING IN FLIGHT, ENGINE WAS RETARDED TO IDLE POWER.  THE FLIGHT RETURNED TO MSP AND LANDED WITHOUT INCIDENT.  OIL LOSS WAS CAUSED BY A DAMAGED OIL CAP SEAL.  MAINTENANCE REPLACED THE OIL CAP O-RING AND RAN THE ENGINE TO CHECK FOR LEAKS, NO LEAKS NOTED.
