NTSB narrative
The pilot reported he was attempting to takeoff in gusty, crosswind conditions. Once airborne, he said the strong right crosswind required almost a 90 degree crab. He stated the left wing contacted the trees, and the plane settled into the trees upright. The owner of the 1,500 feet long by 100 feet wide, north-south airstrip, who witnessed the accident, said winds and downdrafts were strong, gusty, and 'rolling over the trees.' The witness said the right crosswind pushed the airplane into the trees. The weather observation from an airport four miles to the west recorded winds from 040 degrees at 13 knots, gusting to 25 knots.
Probable cause
The pilot's intentional takeoff into known adverse weather. Factors associated with this accident are crosswinds, gusts, and downdrafts.

- 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.
