- Defining eventThe single coded event the NTSB judges best describes what happened (records from 2008 on). Older records name the first occurrence in the sequence instead. Glossary
- Hard landing
- DamageDestroyed: beyond practical repair. Substantial: damage that affects the structure, performance or handling and normally needs major repair. Minor: less than that. Glossary

NTSB narrative
The non-certificated pilot reported that, during his first flight in the recently purchased airplane, he encountered turbulence on the base and final legs of the airport traffic pattern. While on the final approach to land, the airplane encountered a gust of wind that resulted in a hard landing. The airplane sustained substantial damage to the lower fuselage and lift struts. The pilot reported that there were no preaccident mechanical malfunctions or failures with the airplane that would have precluded normal operation. The pilot reported that at the time of the accident he was landing on runway 36 with wind variable at 5 knots, gusting to 10 knots.
Probable cause
The non-certificated pilot's improper landing flare in turbulent wind conditions, which resulted in a hard landing.

Source notes (4)
- 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, coordinates, cause areas. 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.
