## Discrepancy

JUST NORTH OF RDU, THE CREW STARTED HAVING PROBLEMS WITH THE PRESSURIZATION.  THE CREW CALLED DISPATCH AND TOGETHER ELECTED TO DIVERT TO RDU.  THE AIRCRAFT WAS FERRIED TO DAY WHERE MAINTENANCE INSPECTED AND REPLACED THE PRESSURE CONTROL UNIT IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 21-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
