## Discrepancy

DFW - FLT 5042 - THE LANDING GEAR WOULD NOT EXTEND.  THE INTRANSIT LIGHT ILLUMINATED, BUTH THE GEAR WOULD NOT COME DOWN.  PERFORMED EMERGENCY EXTENSION PROCEDURES AND GOT THREE GREEN LIGHTS AT THAT POINT.  LANDED WITHOUT FURTHER INCIDENT. REMOVED AND REPLACED THE LANDING GEAR CONTROL VALVE.  OPERATIONAL CHECK GOOD.
