UPON ARRIVAL AT HIS ORIGINAL DESTINATION, THE PILOT CYCLED THE GEAR SIX TIMES, BUT THE GREEN GEAR-DOWN LIGHT FOR THE RIGHT MAIN GEAR DID NOT ILLUMINATE. AFTRER USING THE EMERGENCY EXTENSION SYSTEM TO BLOW THE GEAR DOWN, THE RIGHT MAIN GEAR-DOWN LIGHT ILLUMINATED. AFTER LANDING, THE PILOT MADE AN INSPECTION OF THE GEAR, BUT DID NOT CONTACT HIS COMPANY MAINTENANCE PERSONAL OR USE AN EXTERNAL LOCK TO HOLD THE GEAR IN A DOWN-AND-LOCKED POSITION. HE THEN DEPARTED FOR HIS FINAL DESTINATION, LEAVING THE GEAR IN THE DOWN POSITION. DURING THE SUBSEQUENT LANDING ROLL, THE RIGHT MAIN GEAR COLLAPSED. CORROSION AND SCORING OF THE METAL WAS FOUND INSIDE THE DOWN-LOCK TUBE WERE THE TEETH OF THE DOWN-LOCK MECHANISM SLIDE INTO THE ENGAGED POSITION.
