NTSB narrative
THE PLT & PAX DEPARTED PHOENIX SKY HARBOR ON A SALES DEMO FLT & LANDED NEARBY AT FALCON FLD. DURING THE RETURN FLT, THE ENG LOST POWER AS THE PLT BEGAN DESCENDING FROM 3800'. HE NOTED THERE WAS NO FUEL FLOW, SO HE USED THE WOBBLE PUMP. THE PLT SAID HE WAS UNABLE TO OBTAIN FUEL PRESSURE, SO HE MOVED THE FUEL SELECTOR TO THE LEFT MAIN TANK. HOWEVER, HE WAS STILL UNABLE TO GET FUEL PRESSURE. THE PLT STATED HE 'TRIED UNSUCCESSFULLY SEVERAL TIMES TO RESTART, SWITCHING TANKS, PUMPING THE WOBBLE PUMP, WITH THE MIXTURE RICH, BUT WAS UNABLE TO RESTART ENGINE.' SUBSEQUENTLY, HE MADE A WHEELS-UP LANDING IN A COTTON FLD, BUT THE ACFT HIT AN IRRIGATION DITCH DURING THE LANDING. THE FUEL SELECTOR WAS FOUND POSITIONEDTO THE R MAIN TANK WHICH HAD ONLY A TRACE OF FUEL REMAINING. SOME FUEL WAS FOUND REMAINING IN THE L MAIN & AUX TANKS. NO FUEL WAS FOUND IN THE CARBURETOR. THE FUEL INDICATOR SELECTOR WAS FOUND POSITIONED TO THE LEFT TANK POSITION. NO PREIMPACT PART FAILURE OR MALFUNCTION WAS FOUND.

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.
