## Discrepancy

FLIGHT 2350 - ON FINAL, APPROXIMATELY 6 MILES OUT, THE CREW ATTEMPTED TO TRIM THE AC RUDDER.  WHEN THE RUDDER TRIM SWITCH WAS RELEASED, THE RUDDER CONTINUED TO TRIM TO FULL LT RUDDER.  THE AIRCRAFT WAS NEVER UNCONTROLLABLE,  AND THE CREW WAS ABLE TO CENTER THE RUDDER TRIM AND THE LANDING WAS UNEVENTFUL.  MAINTENANCE REPLACED THE AILERON/RUDDER TRIM PANEL DUE TO A STUCK SWITCH.  THE OPERATIONAL CHECKS WERE GOOD AND THE AIRCRAFT WAS RETURNED TO SERVICE.
