While approaching elko for landing, I heard AWOS report winds as 250/21630, and unicom reported winds as 230/19631 while I was on downwind for runway 23. While I was on base and final of my visual pattern, I performed landing checks, confirming I had a green gear down light, and flew a full flap pattern and landing. Approximately 10 ft in the air above the runway I felt the aircraft buffeted by a wind gust which caused it to yaw to the right about 10 degrees, and then correct back. It didn't balloon, but instead it settled for a firm, but not particularly hard touchdown. Immediately upon landing, the right side of the aircraft settled lower than it should have (I had touched down approximately wings level--possibly right main gear first) and the gear warning horn began to sound. I gave left aileron immediately to hold the wings level and held that for a few seconds until losing aileron authority/authorized as the airspeed bled off. After a few seconds, the right wingtip began to contact the runway followed almost immediately with the propellers of the right engine contacting the runway (power was at idle). Soon after, the aircraft began to depart the runway off the right side and came to rest 50 yards off the side of the runway a little over 1000 ft from the initial landing point. I cutoff mixtures, fuel selectors off, and battery, generators, and magnetos off and emergency egressed. Regarding the landing, I think the wind gust that hit me made it difficult to make an optimal, smooth landing, but it also wasn't anything that warranted a go around. 2 pilot witnesses on the ground said it appeared my landing was good, and I don't think I did anything that caused the gear to collapse. I suspect a mechanical failure in the gear.

Title: ATX SMT R LNDG GEAR COLLAPSED DURING LNDG ROLL RESULTING IN THE ACFT VEERING OFF THE SIDE OF THE RWY.
Narrative: WHILE APCHING ELKO FOR LNDG, I HEARD AWOS RPT WINDS AS 250/21630, AND UNICOM RPTED WINDS AS 230/19631 WHILE I WAS ON DOWNWIND FOR RWY 23. WHILE I WAS ON BASE AND FINAL OF MY VISUAL PATTERN, I PERFORMED LNDG CHKS, CONFIRMING I HAD A GREEN GEAR DOWN LIGHT, AND FLEW A FULL FLAP PATTERN AND LNDG. APPROX 10 FT IN THE AIR ABOVE THE RWY I FELT THE ACFT BUFFETED BY A WIND GUST WHICH CAUSED IT TO YAW TO THE R ABOUT 10 DEGS, AND THEN CORRECT BACK. IT DIDN'T BALLOON, BUT INSTEAD IT SETTLED FOR A FIRM, BUT NOT PARTICULARLY HARD TOUCHDOWN. IMMEDIATELY UPON LNDG, THE R SIDE OF THE ACFT SETTLED LOWER THAN IT SHOULD HAVE (I HAD TOUCHED DOWN APPROX WINGS LEVEL--POSSIBLY R MAIN GEAR FIRST) AND THE GEAR WARNING HORN BEGAN TO SOUND. I GAVE L AILERON IMMEDIATELY TO HOLD THE WINGS LEVEL AND HELD THAT FOR A FEW SECONDS UNTIL LOSING AILERON AUTH AS THE AIRSPD BLED OFF. AFTER A FEW SECONDS, THE R WINGTIP BEGAN TO CONTACT THE RWY FOLLOWED ALMOST IMMEDIATELY WITH THE PROPELLERS OF THE R ENG CONTACTING THE RWY (PWR WAS AT IDLE). SOON AFTER, THE ACFT BEGAN TO DEPART THE RWY OFF THE R SIDE AND CAME TO REST 50 YARDS OFF THE SIDE OF THE RWY A LITTLE OVER 1000 FT FROM THE INITIAL LNDG POINT. I CUTOFF MIXTURES, FUEL SELECTORS OFF, AND BATTERY, GENERATORS, AND MAGNETOS OFF AND EMER EGRESSED. REGARDING THE LNDG, I THINK THE WIND GUST THAT HIT ME MADE IT DIFFICULT TO MAKE AN OPTIMAL, SMOOTH LNDG, BUT IT ALSO WASN'T ANYTHING THAT WARRANTED A GAR. 2 PLT WITNESSES ON THE GND SAID IT APPEARED MY LNDG WAS GOOD, AND I DON'T THINK I DID ANYTHING THAT CAUSED THE GEAR TO COLLAPSE. I SUSPECT A MECHANICAL FAILURE IN THE GEAR.
