NTSB narrative
The airplane experienced a hard landing. During the hard landing the right main landing gear attachment fractured. Examination of the fractured part revealed about 95% from overstress fracture and the remainder from a corrosion stress fracture.
Probable cause
the pilot's misjudging the flare leading to a hard landing, and the kit manufacturer's (Supplemental Type Certificate holder's) inadequate design leading to a corrosion stress fracture of the landing gear attachment. A factor was the landing gear attachment corroded.

- 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.
