Read the NTSB report, winds were from the left, and shortly before TD, the stick actuator neutralized the xw controls and didn't flare....so the acft was drifing right as the left main impacted first with a significant sideways acceleration, resulting in a hard rock onto the right main, which collapsed.....not just landing in a crab.

The left main impact was just beyond the limit of 12 fps @ 12.5, the right hit @ 14.5 fps
