## Discrepancy

DURING APPROACH UPON SELECTING GEAR DOWN THE FLIGHT CREW RECEIVED A NOSE WHEEL STEERING AND NOSE WHEEL POWER UP FAIL MESSAGE.  THE FLIGHT CREW ADVISED THE TOWER THAT A MISSED APPROACH WAS REQUIRED TO COMPLETE THE CHECKLIST.  THE FLIGHT CREW THEN RE-ENTERED THE APPROACH AND THE TOWER HAD EMERGENCY VEHICLES RESPOND.  THE LANDING WAS MADE WITHOUT INCIDENT.  MAINTENANCE INSPECTED AND REPLACED THE HYDRAULIC STEERING CONTROL MANIFOLD IN ACCORDANCE WITH DORNIER MAINTENANCE MANUAL 32-50-00.  OPERATIONAL CHECKS WERE COMPLETED AND THE AIRCRAFT RETURNED TO SERVICE.
