## Discrepancy

DURING LANDING, FLIGHT 4180 EXPERIENCED A NOSE WHEEL STEERING FAIL CAS MESSAGE AND EXECUTED A MISSED APPROACH.  THE CREW FOLLOWED THE QUICK REFERENCE HANDBOOK AND TURNED OFF THE NOSE WHEEL STEERING AND ANTI-SKID.  FLIGHT 4180 THEN LANDED WITH NO FURTHER INCIDENTS.  MAINTENANCE INSPECTED AND RERACKED THE NOSE WHEEL STEERING CONTROL UNIT THEN PERFORMED TAXI CHECKS IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 32-00-00.  THE PROBLEM COULD NOT BE DUPLICATED DURING THESE OPERATIONAL CHECKS AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
