## Discrepancy

CLE FLT 2521 CREW REPORTED THAT THE SPOILERS OPENED ON TAKEOFF ROLL AT APPROXIMATELY 100 KIAS.  THE SPOILERS INDICATED OPEN ON THE EICAS SYSTEM.  THE CREW THEN ABORTED THE TAKEOFF AND RETURNED TO THE GATE WITHOUT INCIDENT.  CLE MAINTENANCE CHECKED ALL SPOILER PROXIMITY SWITCHES AND LANDING GEAR WHEEL HUBS FOR PROPER INSTALLATION AND OPERATIONAL CHECKS.  NO DEFECTS WERE NOTED.  CLE MAINTENANCE REMOVED AND REPLACED THE SPOILER CONTROL UNIT.  OPERATIONAL CHECKS WERE PERFORMED AND THE DISCREPANCY WAS CLEARED.
