## Discrepancy

IAH - FLIGHT 4451 THE CREW REPORTED THAT THE RUDDER TRIM KEEPS TRIMMING TO THE LEFT IN FLIGHT. THE AIRCRAFT LANDED AT IAH WITHOUT INCIDENT. MAINTENANCE REMOVED AND REPLACED THE YAW TRIM SWITCH, OPERATIONALLY TESTED WITH NO DEFECTS AND THE AIRCRAFT WAS APPROVED FOR RETURN TO SERVICE.
