NTSB narrative
AFTER TAKEOFF WITH THE FUEL SELECTOR POSITIONED TO THE AUXILIARY FUEL TANK, THE ENG QUIT DUE TO FUEL EXHAUSTION IN THAT TANK. THE PLT REPOSITIONED THE FUEL SELECTOR TO THE MAIN FUEL TANK POSITION WHICH CONTAINED AN ADEQUATE SUPPLY OF FUEL, BUT THE ENG STARTED ONLY MOMENTARILY, THEN QUIT. THE PILOT LANDED THE ACFT GEAR UP IN A FIELD. EXAM OF THE ACFT BY AN FAA AIRWORTHINESS INSPECTOR REVEALED THAT A RUBBER FUEL LINE WHICH CONNECTS THE MAIN TANK TO THE FUEL SELECTOR WAS BLOCKED BY CONTAMINANTS. THE PLT HAD IN THE PAST OPERATED THE ENG USING AUTOMOTIVE FUEL WITHOUT AN STC. HE WAS ALSO AWARE BEFORE THE ACCIDENT THAT THE ENG WOULD LOSE POWER WITH THE FUEL SELECTOR POSITIONED TO THE MAIN TANK.
Probable cause
OPERATION BY THE OWNER/PILOT-IN-COMMAND WITH KNOWN DEFICIENCIES IN EQUIPMENT AND FUEL STARVATION DUE TO A BLOCKED FUEL LINE.

- 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.
