NTSB narrative
On final approach, the engine sputtered, lost fuel pressure, then lost all power. With the total loss of power, the pilot initiated a forced landing to a field. During the landing, the airplane struck a fence and subsequently nosed over. The pilot reported that there were about 15 gallons of fuel on board before he departed on the first of two sightseeing flights and that the left tank had substantially more fuel than the right tank. When the airplane wreckage was recovered, about 10 gallons of fuel reportedly were drained. According to the airplane manufacturer, about 3 gallons of this fuel would have been unusable, and it is likely one of the fuel tanks was nearly empty. However, the investigation was unable to determine the actual fuel quantity in the airplane’s tanks because the pilot recovered and moved the airplane wreckage without oversight by federal officials. The circumstances of the accident are consistent with the pilot likely not managing the fuel on board properly, resulting in fuel starvation and a total loss of engine power.
Probable cause
The pilot’s improper in-flight fuel management, which led to fuel starvation and a total 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: local date, investigation status, cause areas. Values present in the bulk record are kept.
