NTSB narrative
The pilot reported that when he departed, about 50 minutes before the accident, the wind was “light out of the north, northwest." As he continued the flight, the wind became variable southwest to northeast. Once he reached his destination, an off-airport snow-covered site, landing the wheel/ski-equipped airplane required a correction for a right quartering headwind that was gusting 20 to 25 knots. During the approach, about 20 to 25 feet above the site, the wind shifted to a tailwind. The airplane landed hard in a three-point attitude. A postaccident inspection of the airplane revealed structural damage to the empennage. There were no reported preaccident malfunctions or failures with the airplane that would have precluded normal operation.
Probable cause
The pilot's loss of control while landing in gusting wind conditions.

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. 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.
