## Discrepancy

THE FLIGHT CREW REPORTED THE THE RUDDER TRIM POSITION INDICATOR INOP DURING FLIGHT. THE MAINTENANCE TEAM DETERMINED THE RUDDER TRIM INDICATOR WAS DEFECTIVE. THE INDICATOR WAS REMOVED AND A REPAIRED UNIT WAS INSTALLED. OPS CHECKS WERE SATISFACTORY AND THE AIRCRAFT WAS RETURNED TO SERVICE.
