## Discrepancy

THE FLIGHT LEVELED OFF AT 27,000 FEET AND THE CREW RECEIVED AN EMERGENCY PARKING BRAKE ACCUMULATOR LOW CAS MESSAGE.  THE CREW REFERENCED THE QUICK REFERENCE HANDBOOK AND WERE DIRECTED TO RETURN TO CHS.  AS FLIGHT 4069 DESCENDED THROUGH 8000 FEET THE CAS MESSAGE EXTINGUISHED AND FLIGHT 4069 LANDED WITH NO FURTHER INCIDENT.  MAINTENANCE INSPECTED AND SERVICED THE EMERGENCY PARKING BRAKE ACCUMULATOR IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 12-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
