Narrative:

Cleared to land, base (right) to final, runway 26R. After performing all proper checks, the aircraft was configured for landing, wind 260 degrees at 6 KTS, straight down the runway. Expecting an uneventful landing, I flared and touched down smoothly. After touching down, the airplane suddenly yawed right. I compensated for the yaw until there was a loss of control during the correction. Afterwards, I ended up on the left side of runway 8L on the grass facing 180 degrees from the direction of intended landing on runway 26R. It was obvious the right landing gear collapsed when I touched down. After the plane was raised and the right gear could be lowered, it was found there was a part of the trailing link which had failed and caused the yaw.

Title: A ROCKWELL COMMANDER SINGLE PLT RPTED THAT HIS R MAIN GEAR COLLAPSED DURING LNDG AT GRR, WHICH CAUSED HIM TO DEPART THE RWY.

Narrative: CLRED TO LAND, BASE (R) TO FINAL, RWY 26R. AFTER PERFORMING ALL PROPER CHKS, THE ACFT WAS CONFIGURED FOR LNDG, WIND 260 DEGS AT 6 KTS, STRAIGHT DOWN THE RWY. EXPECTING AN UNEVENTFUL LNDG, I FLARED AND TOUCHED DOWN SMOOTHLY. AFTER TOUCHING DOWN, THE AIRPLANE SUDDENLY YAWED R. I COMPENSATED FOR THE YAW UNTIL THERE WAS A LOSS OF CTL DURING THE CORRECTION. AFTERWARDS, I ENDED UP ON THE L SIDE OF RWY 8L ON THE GRASS FACING 180 DEGS FROM THE DIRECTION OF INTENDED LNDG ON RWY 26R. IT WAS OBVIOUS THE R LNDG GEAR COLLAPSED WHEN I TOUCHED DOWN. AFTER THE PLANE WAS RAISED AND THE R GEAR COULD BE LOWERED, IT WAS FOUND THERE WAS A PART OF THE TRAILING LINK WHICH HAD FAILED AND CAUSED THE YAW.
