## Discrepancy

AFTER TAKEOFF, FLIGHT 4126 RECEIVED A RIGHT HAND ENGINE SURGE AND A RIGHT OIL PRESSURE CAS MESSAGE.  THE CREW DECIDED TO RETURN TO THE FIELD AND LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE RIGHT HAND HIGH PRESSURE PUMP IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 61-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
