## Discrepancy

CREW REPORTED THAT DURING FLIGHT RECEIVED AND AILERON MISTRIM MESSAGE AND THAT THE AILERONS WERE BINDING WHILE ATTEMPTING TO TURN RIGHT.  THE CREW FORCED THE AILERONS FREE AND THE AIRCRAFT FLEW NORMALLY THE REST OF THE FLIGHT.  THE AIRCRAFT LANDED WITHOUT INCIDENT.  THE AIRCRAFT WAS FERRIED TO CMH AND FURTHER TROUBLESHOOTING WAS PERFORMED.  AS A RESULT, BOTH AHRS COMPUTERS WERE REPLACED, ALONG WITH THE LEFT RVDT.  THE AIRCRAFT WAS THEN TEST FLOWN FOR OVER AN HOUR WITH NO DEFECTS NOTED AND THE AIRCRAFT WAS RETURNED TO SERVICE.
