NTSB investigators may not have traveled in support of this investigation and used data provided by various sources to prepare this aircraft accident report.

While approximately 1,800 feet above the ground (AGL), during a full-power climb, the aircraft's engine lost power and the propeller stopped turning. The pilot, who was over a town at the time of the power loss, attempted a forced landing in an open field, but the airplane struck a tree during the flare/touchdown. It was later discovered that the front cover on the engine-driven fuel pump was out of alignment by 60 degrees, resulting in a restriction to fuel flow through the pump. The pilot, who was not aware of the alignment marks on the surface of the pump, said that he had disassembled and reassembled the pump while trying to fit it in the aircraft during the construction process.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

Fuel starvation caused by the partial blockage of the fuel pump chambers as a result of the misalignment of the fuel pump front cover by the pilot/builder. Factors include trees in the area in which the pilot attempted the forced landing.
