NTSB narrative
The private pilot reported that the landing was "normal" but that, during the landing roll, he noticed that the experimental, amateur-built airplane started veering to the left. Shortly thereafter, the right wing suddenly dropped and impacted the runway. He was unable to maintain directional control of the airplane, and it veered off the runway because the right main landing gear (MLG) had collapsed.
Postaccident examination of the right MLG assembly revealed that the right main tire and wheel had separated from the airplane and that a strut had separated about midpoint. Examination of the fracture features of the right MLG assembly revealed that they exhibited matte-gray features on slant angles, consistent with a ductile overstress fracture. No evidence of preexisting cracks or significant corrosion was observed. The right MLG assembly likely failed due to a hard landing and/or side loading on the MLG.
Probable cause
The failure of the right main landing gear assembly due to overstress fracture.

- 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.
