NTSB narrative
THE ACFT NOSED OVER DURING A FORCED LANDING AFTER A POWER LOSS. THE PLT STATED AFTER THE ACCIDENT THAT THE ENGINE LOST POWER DURING A ROLL MANEUVER. THE ENGINE RAN FOR A SHORT TIME AT APRX 1800 RPM AND THEN STOPPED COMPLETELY. THE PLT LANDED IN A CULTIVATED WHEAT FIELD WHILE ENROUTE TO THE NEAREST AIRPORT (SUNDANCE). DURING A POST ACCIDENT CHECK THE ENGINE STARTED BUT WOULD NOT DEVELOP FULL POWER AND CUT OUT AT 1300 RPM. WHEN THE CARBURETOR WAS REMOVED AND CHECKED IT WAS FOUND TO CONTAIN A TRASH BUILD-UP AT THE DISCHARGE NEEDLE PLUS A LEAN MIXTURE SETTING.

Source notes (4)
- 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.
