The non-certificated pilot reported that as, he maneuvered the airplane to land in an open field, his flight path was nearing people and a building, so he added power, however too much power was added. This resulted in the nose of the airplane pitching up rapidly, which was followed by an aerodynamic stall and a nose low impact in the field. The airplane’s tail boom, fuselage, and wings sustained substantial damage. A video taken from the ground captured nearly the entire accident flight. Its contents largely corroborate the pilot’s account of what happened. The pilot reported that there were no preimpact mechanical malfunctions or failures with the airplane. He further reported that the accident flight was only his second flight in the airplane and he had not received any flight training to fly this airplane prior to flight. He believed the airplane was an “ultralight”, however, due to the fuel tanks size and number of seats, it did not meet the criteria stated in Code of Federal Regulations Part 103.
