NTSB narrative

The pilot attempted to the land the airplane on a dirt road to inspect some cattle in a field. During the landing, the main landing gear settled into soft terrain and the airplane yawed left approximately 30 degrees. The pilot attempted to execute a go-around, but was unsuccessful. The airplane impacted a small tree and came to rest on its nose.

Probable cause

The pilot's improper decision to execute an off-airport landing on a dirt road. A contributing factor was the soft terrain.

  • 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.
