## Discrepancy

DURING FLIGHT, THE CREW DIVERTED DUE TO THE RT ROLL TRIM WAS NOT RESPONDING TO COMMANDS. DIVERTED AND LANDED FOR REPAIRS. TROUBLESHOOTING IDENTIFIED THE RT ROLL TRIM ACTUATOR DEFECTIVE. AN OVERHAULED ACTUATOR WAS INSTALLED. FUNCTIONAL CHECKS WERE SATISFACTORY. THE AIRCRAFT WAS RETURNED TO SERVICE.
