## Discrepancy

ON APPROACH TO THE AIRPORT, THE GEAR WAS SELECTED DOWN BUT THERE WAS NO INDICATION THE NOSE GEAR WAS DOWN AND LOCKED.  THE GEAR WAS CYCLED SEVERAL TIMES AND CYCLED MANUALLY ONCE BUT THERE WAS STILL NO NOSE GEAR DOWN INDICATION.  THE ACFT RETURNED TO BASE.  ON APPROACH THE GEAR WAS AGAIN SELECTED DOWN AND THIS TIME ALL GEAR INDICATED DOWN AND LOCKED.  A TOWER FLY-BY WAS CONDUCTED AS A SAFETY PRECAUTION AND THE ACFT LANDED WITHOUT INCIDENT.  MX TROUBLESHOT THE PROBLEM TO A INTERMITTENT NOSE GEAR DOWNLOCK SWITCH AND REPLACED THE SWITCH.
