## Discrepancy

(CAN) THE NR 2 RUDDER HYDRAULIC CAUTION LIGHT ILLUMINATED DURING FLIGHT. THE FLIGHT CREW SELECTED THE RUDDER NR  2 SHUT OFF SWITCH AND ALL THREE RUDDER CAUTION LIGHTS CAME ON. THE AIRSPEED WAS REDUCED TO LESS THAN 200 KNOTS AND THE AIRCRAFT RETURNED TO THE STATION.  MAINTENANCE REPLACED THE NR 2 RUDDER HYDRAULIC PRESSURE SWITCH, RESET THE SYSTEM AND COMPLETED ALL FURTHER CHECKS PRIOR TO RELEASING THE AIRCRAFT TO SERVICE.
