NTSB narrative
THE HOMEBUILT SONERAI II MADE AN OFF AIRPORT LANDING 3 MINUTES AFTER TAKEOFF. THE AIRCRAFT RECEIVED SUBSTANTIAL DAMAGE AND THE SOLE OCCUPANT WAS UNINJURED. POST CRASH EXAMINATION OF THE AIRCRAFT SHOWED THE FUEL TANK WAS EMPTY. HOWEVER, THERE WAS FUEL IN THE GASCOLATOR TO THE CARBURATOR. WHEN THE ENGINE WAS ROTATED NO SPARK WAS OBSERVED FROM THE MAGNETOS. AFTER THE 'P' LEAD WAS REMOVED AND REINSTALLED, AND THE IGNITION SWITCH (MANUFACTURED FOR FARM TRACTORS) WAS CYCLED, SPARK WAS OBSERVED FROM THE MAGNETOS.

- 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.
