NTSB narrative
The airplane was equipped with manual fuel shutoff valves located in each engine compartment which can only be accessed while on the ground; the valves were installed following building of the airplane to prevent fuel migrating into the oil reservoir. Both valves were closed when the flight departed, and shortly after takeoff when the pilot turned off both auxiliary fuel pumps, both engines quit. While descending for a forced landing, the airplane collided with and remained suspended in a 100-foot tall tree. The pilot further stated there was no checklist for the airplane which would have prevented the accident, and there was no mechanical failure or malfunction.
Probable cause
The pilot's inadequate preflight planning/preparation for his failure to assure that the fuel shutoff valves located in both engine compartments were turned on and also the failure of the pilot to have a checklist to outline preflight items.

- 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, coordinates. 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.
