Probable cause & findings

The failure of the weld on the airplane’s left main landing gear axle support strut during landing, which resulted in a loss of directional control.

Factual narrative

According to the pilot in the experimental amateur-built airplane, during landing the airplane bounced and the pilot added power. The airplane landed on the runway, but the left side of the airplane "dropped" to the ground. The airplane exited the left side of the runway where it came to rest. The airplane sustained substantial damage to the horizontal stabilizer.
