## Discrepancy

DURING APPROACH TO LAND AFTER SELECTING GEAR DOWN AND COMPLETION OF THE CYCLE, THE NOSE GEAR DOWNLOCK GREEN INDICATOR LAMP FAILED TO ILLUMINATE.  THE IN TRANSIT LIGHT WAS EXTINGUISHED AND THE NOSE GEAR WAS VISIBLE IN THE DOWN POSITION IN THE VIEWING MIRROR.  LANDING WAS ABORTED AND AIRCRAFT RETURN TO BASE. AN EMERGENCY GEAR EXTENSION PROCEDURE WAS FOLLOWED OUT OF CAUTION.  AIRCRAFT LANDED WITHOUT INCIDENT.  A BROKEN WIRE WAS FOUND AT THE RING TERMINAL FOR THE NOSE GEAR DOWNLOCK INDICATOR CIRCUIT WHERE IT ATTACHES TO THE NOSE GEAR WELL STRUCTURE.  THE RING TERMINAL WAS REPLACED, EMERGENCY EXTENSION BOTTLE WAS RESET AND SERVICED, HYDRAULICS SERVICED AND GEAR SWING CHECKS PERFORMED SATISFACTORY.
