## Discrepancy

CLT  FLT1445,  DURING CLIMB-OUT FROM CLT, EN ROUTE TO MIA, THE NOSE GEAR WOULD NOT RETRACT.   WITH THE GEAR HANDLE UP, CREW RECEIVED BOTH A RED AND GREEN LIGHT INDICATION.  CREW EXTENDED GEAR AND RECEIVED ALL THREE GREEN LIGHTS.  FLIGHT RETURNED TO FIELD IN CLT AND LANDED WITHOUT FURTHER INCIDENT.  MAINTENANCE REMOVED AND REPLACED NOSE LANDING GEAR HYDRAULIC MODULE AND THE NOSE GEAR HYDRAULIC FUSE.  BLED SYSTEM AND CYCLED GEAR NUMEROUS TIMES.  OPERATIONAL CHECK AND LEAK CHECK GOOD.
