Probable cause

The failure of the pilot to maintain airspeed, which resulted in a stall and spin at a low altitude. Also causal to the accident was the lack of experience of the pilot in this make and model airplane.

Analysis

The pilot was flying the experimental, home-built airplane for the first time. He expressed reservations about flying the airplane. The pilot's family arrived at the airport with a video camera to record the flight. After much hesitation, the pilot took off. He circled the airport for several minutes at a low altitude. Then the airplane stalled and spun into the ground.
