NTSB narrative
The pilot stated that he used a slightly higher final approach airspeed to compensate for any possible wind gusts. After the aircraft touched down, a wind gust lifted the aircraft back off the runway surface. The aircraft settled back to the runway and the pilot immediately applied brakes, raised the flaps, and held the nose off the ground. The pilot reported that the braking action of the aircraft was minimal due to hydroplaning. The pilot stated that a go-around was not possible due to the length of runway remaining and a tree line that was present at the end of the runway. The aircraft traveled off the end of the runway where it impacted a deep rut in the terrain. The nose gear of the aircraft dug into the rut causing the aircraft to nose over. Post accident inspection of the airplane revealed evidence of reverted rubber on both the left and right main landing gears.
Probable cause
the lack of effective braking due to hydroplaning. Contributing factors to the accident were the trees off the end of the runway that made a go-around not possible and the ditch off the end of the runway.

- 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.
