NTSB narrative
The sport pilot of the weight-shift control airplane reported that, during landing, the airplane touched down hard, fracturing the engine mount sway bars; the airplane subsequently bounced back into the air. In an attempt to prevent a stall, the pilot elected to go around. As he gained altitude, he realized that the airplane was difficult to control.
A witness reported that the airplane made four subsequent landing attempts without touching down. On the fifth approach, the airplane appeared to land hard, bounce, and touch down again before departing the runway. The pilot reported that, upon touchdown, he felt the airplane suddenly accelerate before it began to cartwheel and departed the left side of the runway where it came to rest inverted.
Postaccident examination revealed no mechanical malfunctions or anomalies that would have precluded normal operation. The engine throttle was controlled via a foot pedal, and it is likely that the pilot inadvertently depressed the pedal during the landing sequence, which resulted in the acceleration he experienced after touchdown and contributed to the loss of control.
Probable cause
The pilot's improper landing flare, which resulted in a fractured engine mount sway bar and subsequent difficulty controlling the airplane, and his inadvertent application of throttle pedal during landing, which resulted in a loss of control.

- 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: investigation status. Values present in the bulk record are kept.
- The date is the local date, which is the same as the UTC date the NTSB stores.
