## Discrepancy

THE NLG INDICATED RED UNSAFE WHEN GEAR WAS EXTENDED, BUT THE COCKPIT INDICATOR PIN SHOWED DOWN AND LOCKED ON APPROACH TO EWR.  A GO-AROUND WAS PERFORMED AND THE AIRCRAFT LANDED WITHOUT INCIDENT.  MAINTENANCE FOUND A BROKEN WIRE ON NLG DOWNLOCK SENSOR.  THE WIRE WAS SPLICED.  A GEAR SWING WAS PERFORMED IAW MM 32-31-00 WITH OPERATION AND INDICATIONS CHECKING GOOD.
