## Discrepancy

DURING CLIMBOUT, THE CREW RECEIVED A EMERGENCY PARKING BRAKE ACCUMULATOR BRAKE CAS MESSAGE.  THE CREW FOLLOWED THE QUICK REFERENCE HANDBOOK AND LANDED AT THE NEAREST SUITABLE AIRPORT.  OUTSTATION MAINTENANCE INSPECTED AND SERVICED THE MAIN SYSTEM PRECHARGE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 12-00-00.  THE AIRCRAFT WAS THEN FERRIED TO CAK WHERE MAINTENANCE INSPECTED AND REPLACED THE  EMERGENCY PARK BRAKE VALVE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 32-00-00.  OPERATIONAL CHECKS WERE COMPLETE AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
