## Discrepancy

FLIGHT 5809 CLE TO DCA - DURING TAKEOFF ROLL, THE FLIGHT CREW RECEIVED A MASTER WARNING FOR A SPOILER TAKEOFF CONFIGURATION MESSAGE ON THE EICAS.  AT THAT TIME THE CREW DECIDED TO ABORT TAKEOFF AND RETURN TO THE GATE WITHOUT INCIDENT.  MAINTENANCE CHECKED ALL HYDRAULIC LEVELS, SPOILERS, AND CONDUCTED AN OPERATIONAL CHECK OF THE SPEED BRAKE WITH THROTTLES ADVANCED WITH NO DEFECTS NOTED.  MAINTENANCE THEN CLEANED ALL PROXIMITY SENSORS AND CONDUCTED ANOTHER OPERATIONAL CHECK IN ACCORDANCE WITH ERJ-145 MM 27-62-00 WITH NO DEFECTS NOTED.
