## Discrepancy

ON APPROACH, THE LEFT HAND MAIN LANDING GEAR FAILED TO INDICATE DOWN AND LOCKED.  AN EMERGENCY WAS DECLARED AND FLIGHT HANDBOOK PROCEDURES WERE FOLLOWED.  THE FLIGHT CREW REPLACED A GEAR INDICATOR LIGHT BULB.  AFTER THE REPLACEMENT, THE INDICATOR ILLUMINATED A DOWN AND LOCKED GEAR CONDITION.  THE FLIGHT CONTINUED THE APPROACH AND LANDED WITHOUT FURTHER INCIDENT.  OUTSTATION MAINTENANCE INSPECTED THE INDICATOR BULBS FOR DEFECTS AND THE AIRCRAFT WAS RETURNED TO SERVICE.
