## Discrepancy

DURING CLIMBOUT FROM PIT, THE FLIGHT CREW RECEIVED A RIGHT HAND PROPELLER OIL PRESSURE CAS MESSAGE.  MAINTENANCE CONTROL INSTRUCTED THE CREW TO RETURN TO THE FIELD.  THE AIRCRAFT LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE OIL PRESSURE SWITCH IN ACCORDANCE WITH DORNIER MAINTENANCE MANAUL 61-21-12.  MAINTENANCE ALSO SERVICED THE OIL.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
