## Discrepancy

IND - FLT 569 - ON APPROACH TO IND WHEN THE LANDING GEAR WAS SELECTED DOWN, THE NOSE GEAR DID NOT INDICATE DOWN AND LOCKED.  CREW PERFORMED A GO AROUND PROCEDURE AND RECYCLED THE LANDING GEAR BUT THE GEAR STILL DID NOT INDICATE DOWN AND LOCKED.  AN ALTERNATE GEAR EXTENSION WAS NOT SUCCESSFUL IN EXTENDING THE NOSE GEAR.  AS A TOWER FLY BY WAS ABOUT TO BE ACCOMPLISHED, THE NOSE GEAR EXTENDED AND A PROPER DOWN AND LOCKED INDICATION ILLUMINATED.  THE FLIGHT LANDED IND WITHOUT FURTHER INCIDENT.  MAINTENANCE FOUND ICE AND SNOW IMPACTED AROUND THE NOSE GEAR DOWN/LOCKED SWITCH.  THEY CLEANED AND LUBRICATED THE NOSE GEAR ACTUATION SYSTEM.  THE LANDING GEAR AND INDICATION SYSTEM THEN TESTED PROPERLY.  (M)
