NTSB narrative
According to the pilot, he was practicing takeoffs and landings on a grass airstrip. He said snow had been removed from the center of the grass airstrip, but not the surrounding area. During his approach to land, bright sunlight reflected off the snow that made him lose his depth perception. The airplane touched down short of the runway, nosing over in deep snow. The pilot reported no preimpact mechanical problems with the airplane. The airplane received substantial damage to both wings.
Probable cause
The pilot's misjudged altitude while landing in bright sunlight on an airstrip surrounded by snow, resulting in an undershoot and a nose over.

- 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.
