NTSB narrative
Shortly after departure, during the ascent, the pilot inadvertently entered IMC conditions. The pilot initiated a turn back to the airport, reacquired the runway at 100 feet above ground level (agl) and approximately mid-field. The aircraft touched down 2,700 feet down the 2,900 foot wet runway at 80 MPH. The aircraft traveled off the end of the runway and collided with a fence. No mechanical malfunctions were reported with the aircraft at the time of the accident.
Probable cause
Proper touchdown point not attained by the pilot. Factors include excessive speed at touchdown, a wet runway, a fence, and the pilot's inadvertent flight into IMC.

- 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.
