NTSB narrative
The pilot was conducting off airport landings in a tundra-tire equipped airplane under Title 14, CFR Part 91. During a telephone conversation with the National Transportation Safety Board investigator-in-charge on April 30, the pilot reported he had flown the airplane for about an hour since his previous off airport landing. He said when he touched down, unknown to him, his right main landing gear tire was flat, and due to its large size, he was unable to maintain directional control on the ground. The airplane exited the intended landing area into rough and uneven terrain. He reported airplane nosed over, and the left wing lift-strut was bent. The pilot said when he examined the deflated tire he found a stick imbedded in the tire, which he believes was from his previous landing.
Probable cause
The damaged and deflated over-sized tire on the main landing gear, which precipitated a loss of directional control during landing.

- 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.
