NTSB narrative
The pilot overflew an off-field landing site multiple times to assess the surface conditions. He observed an area with tire tracks and concluded that the surface was stable enough to perform a landing. He configured the airplane for a soft field landing, with the main landing gear touching the ground first. He reported that the ground felt firm as he lowered the nose; however, as the nosewheel touched the surface, the airplane experienced a sudden deceleration and nosed over. The airplane sustained substantial damage to the wings and vertical stabilizer during the accident sequence. Postaccident examination of the landing surface revealed that it consisted of soft, wet mud, topped with a shallow dry crust.
Probable cause
The pilot's selection of unsuitable terrain for landing, which resulted in 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.
