## Discrepancy

LANDING GEAR WOULD NOT EXTEND NORMALLY FOLLOWED THE QRH.  GEAR DID NOT EXTEND UNTIL THE EMERGENCY LANDING GEAR HANDLE WAS PULLED.  THE FI OVERRIDE KNOB HAD TO BE PULLED, OBTAINED THREE GREEN DOWN AND LOCKED INDICATIONS.  MAINTENANCE REPLACED THE LANDING CONTROL VALVE AND RELAY 15GA.  ALL CHECKS GOOD.
