## Discrepancy

CREW REPORTED THAT ON APPROACH WHEN THE LANDING GEAR WAS SELECTED DOWN, THERE WAS A RED NOSE LANDING GEAR INDICATION AND A LANDING GEAR LEVER DISAGREE MESSAGE ON EICAS.  THE GEAR WAS RETRACTED AGAIN AND THEN EXTENDED WITH NO FURTHER DIFFICULTIES.  THE AIRCRAFT THEN LANDED WITHOUT INCIDENT.  MAINTENANCE INSPECTED THE NOSE LANDING GEAR AND FOUND THE CONNECTOR LOOSE ON THE NOSE LANDING GEAR DOWN LOCK PROX SWITCH.  THE SWITCH AND CONNECTOR WERE CLEANED AND RE-CONNECTED WITH NO FURTHER DEFECTS NOTED.
