## Discrepancy

WHILE CLIMBING THROUGH FLT 020, THE CREW RECEIVED AN INTERMITTENT RIGHT HAND PROPELLER LOW OIL PRESSURE CAS MESSAGE.  REACHING FLT 100 THE MESSAGE REMAINED CONSTANT, THE CREW DECIDED TO RETURN TO THE FIELD.  THE AIRCRAFT WAS FERRIED TO AKRON WHERE MAINTENANCE INSPECTED AND REPLACED THE RIGHT HAND PITCH CONTROL UNIT IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 61-21-06.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
