NTSB narrative
The sport instructor pilot reported that during a student pilot’s first dual instructional flight, the engine lost power while on a 1.5 mile final to land. The instructor made a forced landing on a dirt road during which the trike nosed over. Post accident examination of the trike revealed 1.2 gallons of fuel remained in the tank, which is at or below the empty markings of the fuel tank. The manufacturer reported that the unusable fuel level is 1.4 gallons. The aircraft was equipped with a fuel monitoring system that activates once the fuel level drops below 2.7 gallons. The pilot told witnesses that he had observed the low fuel warning on the instrument panel. The aircraft flight manual had a typographical error, which stated the unusable fuel was 0.4 gallons. As a result of this accident investigation the manufacturer corrected the error and reissued the corrected page to the aircraft flight manual.
Probable cause
A loss of engine power as a result of fuel exhaustion due to the pilot's improper decision to continue the flight after the low fuel warning. Contributing to the accident was the typographical error in the flight manual concerning the unusable fuel quantity.

- 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.
