What was found
AS THE PILOT AND COPILOT WERE COMING IN TO LAND, LANDING GEAR WAS LOWERED AND NOTICED THAT THE FRONT (NOSE) WHEEL LANDING GEAR INDICATION WAS RED. CREW DECIDED TO PERFROM LOW APPROACH OVER RUNWAY FOR THE TOWER TO SEE IF LANDING GEAR APPEARED TO BE DOWN. TOWER INFORMED THE GEAR APPERED TO BE DOWN BUT BECAUSE OF THE UNCERTAINTY OF IT BEING DOWN AND LOCKED, EMERGENCY WAS DECLARED. FLIGHT CREW PROCEEDED TO RECOVER ALTITUDE AND COMPLETE EMERGENCY CHECKLIST USING 'QRH', AFTER COMPLETITION PROCEEDED TO LAND. AS THE AIRCRAFT CAME IN CONTACT WITH THE RUNWAY ALL 3 TIRES TOUCHED DOWN WITHOUT DISCREPANCIES. AFTER THE AIRCRAFT SLOWED DOWN TO ABOUT 5 KNOTS FLIGHT CREW STARTED THE TURN TOWARDS THE RUNWAY EXIT AT WHICH POINT THE NOSE WHEEL GEAR COLLAPSED LEAVING THE PLANE IN THE MIDDLE OF RUNWAY. PILOTS PROCEEDED TO SHUT DOWN AND NO PERSONS WERE INJURED IN THE EVENT. AFTER AIRCRAFT WAS LIFTED AND NOSE GEAR SECURED MAINTENANCE PERSONEL MOVED AIRCRAFT TO MAINTENANCE AREA. AFTER TROUGH INSPECTION FOUND THE NOSE GEAR DIDN'T LOCK BECAUSE NOSE GEAR ACTUATOR HAD FAILED AND DIDN'T HAVE ENOUGH FORCE TO MOVE THE GEAR TO LOCKED POSITION. MAINTENANCE CREW REPLACED ACTUATOR AND PERFORMED OPERATIONAL CHECK, AT THIS TIME LANDING GEAR WAS CONFIRMED TO BE LOCKING AND REFLECTING THE CORRECT INDICATION. ALL OTHER SKIN DAMAGE SUSTAINED DETERMINED TO BE NON CRITICAL AND REPAIRED IAW AIRCRAFT STRUCTURAL REPAIR MANUAL. NOTE: ALL "HOURS" PROVIDED FOR LANDING GEAR COMPONENTS ARE CYCLES.
