NTSB narrative
The airplane departed to the northwest from a private grass airstrip situated behind the pilot's residence. The passenger reported that shortly after takeoff the airplane encountered a large wind gust that pushed the airplane to the left (southwest). After encountering a second wind gust, the airplane banked sharply and then descended vertically into trees and terrain. The passenger recalled that the airstrip's windsock did not indicate that there was significant wind prior to the accident flight. The pilot had no recollection of the accident flight. A weather observation station located about 16 nm south-southeast of the accident site reported the wind was from the east at 5 knots with no gusts. Another weather observation station located about 23 nm west of the accident site reported the wind was from the west-southwest at 4 knots, gusting to 10 knots.
Probable cause
The pilot's failure to maintain adequate airspeed and aircraft control during initial climb after takeoff. Contributing to the accident was the gusting wind condition.

- 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. 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.
