Read the full NTSB narrative

The pilot reported that, during the landing approach, he selected the landing gear selector switch to the down position, which was followed by "three greens," indicating that the landing gear was down, locked, and safe for landing. He noted that all three occupants verified and verbally confirmed that the landing gear was "down and locked." The airplane landed uneventfully, but as the pilot started a left turn onto the taxiway, the right main landing gear collapsed, and the right wing struck the ground, sustaining substantial damage. A postaccident examination of the landing gear system revealed that the right main landing gear assembly bell crank pivot bolt had sheared and displayed features consistent with a ductile overstress fracture from shear loading.
