Narrative:

This accident happened on the final leg of a 4 leg round robin part 135 cargo flight. The leg on which this accident occurred was from ind to stl. It was a routine flight. I had been cleared for the visual approach to runway 24 at stl approximately 27 NM out. While tracking the localizer and the GS, and approaching the OM, I referenced the before landing checklist for the small aircraft. At the OM, I selected approach flaps and landing gear down. Holding the gear lever in the down position I visually saw the left main gear coming down and looked back at the position lights where the green gear down light illuminated. I changed radio frequencys to tower and was cleared to land on runway 24 and to hold short of runway 30L. At the middle marker I selected full flaps with a short field to normal landing in mind to turn off within the 4000 ft of runway available. The flare to landing appeared normal, there was no gear unsafe horn on and the touchdown was normal, except the aircraft felt like it bounced a couple of ft and was settling back to the runway. I believe this feeling was actually the main landing gear touching then collapsing, thus the sinking back to the runway feeling. After this landing I saw light from my peripheral vision. As I turned my head I saw sparks coming from the tail tie-down. At this point, I notified tower of the situation and proceeded to secure the aircraft. After the aircraft came to rest, I escaped through the right passenger door and found no fire, but the left wing tip and left horizontal stabilizer were damaged.

Title: PLT OF AN SMA SEL ATX CARGO ACFT EXPERIENCED LNDG GEAR COLLAPSE DURING LNDG TOUCHDOWN.

Narrative: THIS ACCIDENT HAPPENED ON THE FINAL LEG OF A 4 LEG ROUND ROBIN PART 135 CARGO FLT. THE LEG ON WHICH THIS ACCIDENT OCCURRED WAS FROM IND TO STL. IT WAS A ROUTINE FLT. I HAD BEEN CLRED FOR THE VISUAL APCH TO RWY 24 AT STL APPROX 27 NM OUT. WHILE TRACKING THE LOC AND THE GS, AND APCHING THE OM, I REFED THE BEFORE LNDG CHKLIST FOR THE SMA. AT THE OM, I SELECTED APCH FLAPS AND LNDG GEAR DOWN. HOLDING THE GEAR LEVER IN THE DOWN POS I VISUALLY SAW THE L MAIN GEAR COMING DOWN AND LOOKED BACK AT THE POS LIGHTS WHERE THE GREEN GEAR DOWN LIGHT ILLUMINATED. I CHANGED RADIO FREQS TO TWR AND WAS CLRED TO LAND ON RWY 24 AND TO HOLD SHORT OF RWY 30L. AT THE MIDDLE MARKER I SELECTED FULL FLAPS WITH A SHORT FIELD TO NORMAL LNDG IN MIND TO TURN OFF WITHIN THE 4000 FT OF RWY AVAILABLE. THE FLARE TO LNDG APPEARED NORMAL, THERE WAS NO GEAR UNSAFE HORN ON AND THE TOUCHDOWN WAS NORMAL, EXCEPT THE ACFT FELT LIKE IT BOUNCED A COUPLE OF FT AND WAS SETTLING BACK TO THE RWY. I BELIEVE THIS FEELING WAS ACTUALLY THE MAIN LNDG GEAR TOUCHING THEN COLLAPSING, THUS THE SINKING BACK TO THE RWY FEELING. AFTER THIS LNDG I SAW LIGHT FROM MY PERIPHERAL VISION. AS I TURNED MY HEAD I SAW SPARKS COMING FROM THE TAIL TIE-DOWN. AT THIS POINT, I NOTIFIED TWR OF THE SIT AND PROCEEDED TO SECURE THE ACFT. AFTER THE ACFT CAME TO REST, I ESCAPED THROUGH THE R PAX DOOR AND FOUND NO FIRE, BUT THE L WING TIP AND L HORIZ STABILIZER WERE DAMAGED.
