## Discrepancy

CREW RECEIVED NOSE WHEEL STEERING INOP MESSAGE AFTER TAKEOFF. THEY DECLARED AN EMERGENCY AND RETURNED TO FIELD IN CLT. ONCE THEY LANDED THEY CONTACTED MX AND WERE ABLE TO TAXI TO A GATE UNDER THEIR OWN POWER. R&R STEERING MANIFOLD IAW CRJ900 AMM 32-51-50-400-801-A01 OPS/LEAK CHECK GOOD AT THIS TIME. R&R SELECTOR VALVE IAW CRJ-900 AMM 32-32-10-000/400-801 AND R&R HYD SYSTEM 3 MANIFOLD PRESSURE SWITCHES IAW CRJ-900 AMM 29-34-01-000/400-802. LEAK CHECKS GOOD AT THIS TIME. GEAR SWING STILL NEEDS PERFORMED FOR OPS TEST. PERFORMED GEAR SWING IAW CRJ 900 AMM 32-30-00-865-801 OPS CHECK GOOD AT THIS TIME.
