## Discrepancy

FLIGHT CREW FOUND THEY COULD NOT OPERATE THE CONTROL WHEEL CCW DIRECTION AFTER ENGINE STARTING.  THE FLIGHT WAS CANCELLED.  MAINTENANCE FOUND THE MICROSWITCH ON THE RT SPOILER CLUTCH ASSY CONTACTING WITH THE BRACKET-UPPER MOUNTING.  THE CONTACT WAS CAUSED BY THE IMPROPER INSTALLATION OF THE MICROSWITCH SCREWS.  BOMBARDIER AEROSPACE IS INVESTIGATING THIS EVENT.
