NTSB narrative

THE PILOT WAS DOING A SALES DEMONSTRATION FLIGHT AND THE PROSPECTIVE BUYER WAS ABOARD. AS PART OF THE DEMONSTRATION, THE PILOT MADE A LOW PASS OVER THE RUNWAY AND THEN HE ENTERED A LEFT DOWNWIND. AS HE TURNED DOWNWIND, THE ENGINE LOST POWER. THE PILOT FORCED LANDED IN A FIELD, BUT THE AIRPLANE STRUCK TREES, AND CARTWHEELED ACROSS THE GROUND. EXAMINATION OF THE AIRPLANE REVEALED THE FUEL STRAINER AND CARBURETOR FUEL BOWL, RESPECTIVELY, HAD TWO AND ONE OUNCE OF FUEL. THE LEFT TANK HAD 8.5 GALLONS OF FUEL. A PLACARD THAT STATED 'NO TAKE-OFF ON RIGHT TANK WITH LESS THAN 1/3 TANK' WAS OVER THE RIGHT FUEL GAGE.

Probable cause

The pilot's failure to select the proper fuel tank, which resulted in fuel starvation and the loss of engine power.

  • 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.
