## Discrepancy

THE FLIGHT CREW REPORTED A INTERMITTENT BINDING IN ROLL CONTROL ON APPROACH, ESPECIALLY TO THE RIGHT.  MILD FORCE WAS REQUIRED TO OVERCOME, THE PILOT NOTED THAT IT DOES NOT APPEAR TO SIMPLY BE HEAVY AERODYNAMIC LOADING.  THE MAINTENANCE AFTER TROUBLESHOOTING POINTED THE PROBLEM TO BE THE SERVO AND REPLACED IT
