NTSB narrative
In a statement to responding county sheriff's deputies, the pilot said that while returning to the airport he experienced a compelling physiological need and landed the aircraft in an open dirt field. During the takeoff ground roll, the aircraft encountered soft soil and nosed over. In his written statement to the Safety Board, the pilot reported that during the takeoff ground roll just prior to rotation, the engine started to run rough. The pilot reported that he aborted the takeoff and could not stop prior to encountering a plowed area of the field. The engine was removed from the aircraft and taken to an engine repair facility. The engine was installed in a test cell, where it started on the first attempt and ran smoothly throughout all normal power ranges.
Probable cause
the pilot's selection of an unsuitable field for an off-airport landing and attempted takeoff.

- 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.
