## Discrepancy

DURING THE TAKEOFF ROLL, FLIGHT 4087, RECEIVED A RIGHT PACK OVER PRESSURE WARNING.  THE FLIGHT CREW ABORTED THE TAKEOFF AND EXITED THE RUNWAY.  THE WARNING MESSAGE HAD CLEARED AND ANOTHER TAKEOFF WAS ATTEMPTED WITH A RIGHT PACK OVER PRESSURE WARNING RESULTING IN ANOTHER ABORTED TAKEOFF.  MAINTENANCE REPLACED THE RIGHT PRESSURE REDUCING SHUTOFF VALVE IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 36-10-00.  FUNCTIONAL CHECKS WERE COMPLETED AND THE AIRCRAFT WAS RETURNED TO SERVICE
