## Discrepancy

ON APPROACH, THE CREW RECEIVED A NOSE WHEEL STEERING FAIL CAS MESSAGE AS WELL AS A PROXY SYSTEM FAIL AND PROXY BYPASS FAIL ON THE SYSTEM PAGE.  THE CREW EXECUTED A MISSED APPROACH AND CALLED MAINTENANCE CONTROL AND THE MESSAGES CLEARED.  DURING THE SECOND APPROACH, THE CREW AGAIN RECEIVED THE SAME MESSAGES, THE CREW COMPLIED WITH THE QUICK REFERENCE HANDBOOK AND THE MESSAGES CLEARED.  THE CREW DECLARED AN EMERGENCY AND FLIGHT 4106 LANDED WITH NO FURTHER INCIDENTS.  MAINTENANCE INSPECTED AND REPLACED THE NOSE WHEEL ELECTRICAL HARNESS IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 32-00-00.  OPERATIONAL CHECKS WERE PERFORMED AND THE AIRCRAFT WAS RELEASED FOR SERVICE.
