NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

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.
The Federal Aviation Administration aviation safety inspector that examined the airplane reported that the weld on the left main landing gear axle support strut had failed with some signs of overload.


The National Transportation Safety Board determines the probable cause(s) of this accident as follows:
  • 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.
