NTSB narrative
WHILE MANEUVERING, THE AIRCRAFTS ENGINE SPUTTERED AND THEN QUIT. DURING FORCED LANDING ON A FRESHLY PLOWED FIELD, THE AIRCRAFTS NOSE WHEEL DUG IN AND COLLAPSED. THE ACIRCRAFT NOSED OVER. THE AIRCRAFT WAS EXAMINED BY AN A & P MECHANIC AND NO ABNORMALITIES COULD BE FOUND. IT IS POSSIBLE, SINCE THE AIRCRAFT WAS FUELD WITH AUTOMOTIVE FFUEL AND IT WAS A WARM DAY (90 DEGREES F.), THAT A VAPOR LOCK OCCURRED.

- 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.
