THE LANDING GEAR DOWN LOCK OVER RIDE WAS ENGAGED AND THE GEAR RETRACTED NORMALLY.  ON DESCENT, THE CREW REPORTED THAT THEY EXTENDED THE GEAR AND GOT A GREEN NOSE AND LT MAIN LIGHT ONLY.  THEY CYCLED THE GEAR TWICE AND GOT 3 GREEN, DOWN AND LOCKED INDICATION ON THE SECOND TRY.  THEY CONTINUED ON AND LANDED SAFELY WITHOUT INCIDENT.  THE CREW DID NOT DECLARE AN EMERGENCY.
