## Discrepancy

AIRCRAFT WAS GROUNDED: AN EMERGENCY WAS DECLARED ON INBOUND INTO DFW DUE TO A NOSE WHEEL STEERING FAILURE WHEN WE PUT THE GEAR DOWN ON APPROACH. FLIGHT CREW RECYCLED GEAR AND IT HAPPENED AGAIN. THE AIRCRAFT LANDED SAFELY AT DFW AND THE AIRCRAFT WAS TOWED TO THE GATE. MAINTENANCE FOUND NOSE WHEEL STEERING SERVO VALVE 6GC FAULTING. AND REPLACED IT PER AMM 32-51-51. A SATISFACTORY OPERATIONAL CHECK WAS ACCOMPLISHED.
