NTSB narrative
According to the pilot, he was test flying the airplane after modifying the landing gear suspension. He stated that the takeoff was routine, and that he stayed over the airport for about 30 to 45 minutes. He said he landed, and upon touchdown on the main wheels, the airplane "deliberately" went to the left. He applied right rudder with no response, and the right wing struck the ground and flipped the airplane inverted. According to the pilot, damage to the airplane consisted of the right upper and lower wing, the left upper wing, and the landing gear. He stated that the parts that failed during the accident were the landing gear lateral cable and the spring windings. The pilot's recommendation to prevent this from happening again would be to have the airplane inspected by an FAA Inspector, and to do more taxi testing before flight.
Probable cause
The failure of the main gear spring during landing, which resulted in a loss of directional control, and a nose over.

- Unreviewed is an editorial label, not an investigation status. API-sourced is not report-checked or human-reviewed. Explicit event totals are used without summing aircraft injury tables; onboard allocation is withheld. Unknown values remain unknown. The operation category is mapped from the NTSB-reported FAR part and has not been reviewed.
- Filled from the NTSB case API where the bulk record had no value: local date, investigation status, coordinates. Values present in the bulk record are kept.
- The date is the local date; the NTSB stores the UTC date 2007-06-25.
