## Discrepancy

FLIGHT 5302 STL TO AUS - DURING TAKEOFF ROLE, THE FLIGHT CREW RECEIVED A SPOILER TAKEOFF CONFIGURATION MESSAGE ON THEIR EICAS.  AT THAT POINT THE CREW DECIDED TO ABORT TAKEOFF AND RETURN TO THE GATE WITHOUT INCIDENT.  MAINTENANCE FOUND NUMEROUS PROXIMITY SWITCHES CONTAMINATED WITH DE-ICING FLUID.  MAINTENANCE CLEANED ALL SPOILER PROXIMITY SWITCHES AND CONDUCTED AN OPERATIONAL CHECK OF THE SYSTEM WITH NO FAULTS FOUND.
