## Discrepancy

DFW - FLIGHT 2658, DURING TAXI THE CREW REPORTED THAT THE SPOILERS WERE DEPLOYING UNCOMMANDED DURING TAXI AND WHEN STATIONARY.  THE AIRCRAFT RETURNED TO THE GATE.  MAINTENANCE REMOVED AND REPLACED THE SPOILER CONTROL UNIT WITH NO HELP, AND THEN REMOVED AND REPLACED THE SPOILER PROXIMITY SENSORS, OPERATIONALLY TESTED WITH NO DEFECTS.  THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
