NTSB narrative
The private pilot was taking off in a tundra tire-equipped airplane from a snow-covered off-airport site, on a Title 14, CFR Part 91 personal flight. He reported that during the takeoff roll the main wheels struck a snowdrift, and the airplane nosed over, resulting in substantial damage to the wings and wing lift struts. The pilot said there were no preaccident mechanical problems with the airplane, and noted in his report to the NTSB that he should not have landed at the off-airport site with a wheel-equipped airplane. The pilot reported that after the accident he manually activated the airplane’s 406 MHz Emergency Locator Transmitter (ELT), and within 20 minutes of doing so, he received a cell phone call from the airplane’s owner inquiring about the accident.
Probable cause
The pilot's decision to land and attempt to takeoff from an unsuitable off-airport site.

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.
