## Discrepancy

AFTER DEPARTURE AND DURING CLIMB WITH AUTOPILOT ON, CREW EXPERIENCED ROLL TRIM RUNAWAY TO THE RIGHT. DISCONNECTING AUTOPILOT STOPPED FURTHER MOVEMENT.  RESET SYSTEM AND OPERATION RETURNED TO NORMAL. MAINTENANCE COULD NOT DUPLICATE ISSUE. MAINTENANCE REPLACED PRINTED CIRCUIT BOARD A194 AS A PRECAUTION.
