## Discrepancy

DURING FLIGHT 4029 TO DCA AN OIL PRESSURE FLUX WAS NOTED BY THE FLIGHT CREW.  THE CREW FOLLOWED THE QRH AND FEATHERED THE RIGHT HAND ENGINE.  THE FLIGHT DIVERTED TO PHL AND LANDED WITHOUT FURTHER INCIDENT.  OUTSTATION MAINTENANCE INSPECTED AND SERVICED THE ENGINE OIL, IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 12-11-00.  ENGINE RUNS AND LEAK CHECKS WERE COMPLETED AND THE AIRCRAFT WAS RETURNED TO SERVICE.  THE ENGINE WAS ALSO PLACED ON OUR OIL WATCH PROGRAM.
