Narrative:

I was cleared for a visual approach to 10R in cmh behind an air carrier medium large transport. I slowed to blue line with landing gear extended and flaps approach with 3 green over the OM. I shot a practice ILS all the way to decision height and then proceeded below the GS to the runway. I wanted to land on the numbers so that I wouldn't have to brake hard to make taxiway C4. I did just that and made a smooth landing. I held the nose off as long as possible with min braking and was cleared to taxi on C4. I started to turn to the left and the right main landing gear collapsed, dropping the right wing and propeller, belly and tail on the ground. I notified ATC, shut everything off and got out of the plane. Upon further inspection it was found that the drag link had broken on the trunnion. The FAA inspector guesses it broke on retraction the takeoff before. I was the first pilot to fly the small transport after a 100 hour inspection, and flew it about 2 hours before it broke. I clearly do not think this was not pilot error at all, but rather a mechanical failure.

Title: ACFT EQUIP PROBLEM FAILURE CAUSES GEAR COLLAPSE AND SUBSEQUENT ACFT DAMAGE.

Narrative: I WAS CLRED FOR A VISUAL APCH TO 10R IN CMH BEHIND AN ACR MLG. I SLOWED TO BLUE LINE WITH LNDG GEAR EXTENDED AND FLAPS APCH WITH 3 GREEN OVER THE OM. I SHOT A PRACTICE ILS ALL THE WAY TO DECISION HEIGHT AND THEN PROCEEDED BELOW THE GS TO THE RWY. I WANTED TO LAND ON THE NUMBERS SO THAT I WOULDN'T HAVE TO BRAKE HARD TO MAKE TAXIWAY C4. I DID JUST THAT AND MADE A SMOOTH LNDG. I HELD THE NOSE OFF AS LONG AS POSSIBLE WITH MIN BRAKING AND WAS CLRED TO TAXI ON C4. I STARTED TO TURN TO THE L AND THE R MAIN LNDG GEAR COLLAPSED, DROPPING THE R WING AND PROP, BELLY AND TAIL ON THE GND. I NOTIFIED ATC, SHUT EVERYTHING OFF AND GOT OUT OF THE PLANE. UPON FURTHER INSPECTION IT WAS FOUND THAT THE DRAG LINK HAD BROKEN ON THE TRUNNION. THE FAA INSPECTOR GUESSES IT BROKE ON RETRACTION THE TKOF BEFORE. I WAS THE FIRST PLT TO FLY THE SMT AFTER A 100 HR INSPECTION, AND FLEW IT ABOUT 2 HRS BEFORE IT BROKE. I CLRLY DO NOT THINK THIS WAS NOT PLT ERROR AT ALL, BUT RATHER A MECHANICAL FAILURE.
