Event Details
The pilot reported that this flight was the first after the aircraft had been completely restored. The start, taxi, and takeoff were normal. During the climb, at about 150 feet above ground level (AGL), the engine suddenly lost power. The pilot determined that he could not return to the airport and chose to land on a highway that runs parallel to the airport.
Landing and Impact
The highway was initially clear of traffic until a truck came over a rise. The pilot maneuvered the aircraft to the side of the road. Just before touchdown, the left wing struck a tree, which spun the aircraft to the left. The main landing gear collapsed, and the right wing contacted the surface.
Post-Accident Findings
After the accident, the pilot immediately exited the aircraft, then returned to secure the cockpit when it was safe. The pilot found that the magneto switches, which are unguarded toggle switches located on the lower left side of the wall, were off. The pilot reported that he did not recall turning off the switches prior to exiting the aircraft. After the aircraft was moved back to the airport, the engine was started and run for several minutes with no evidence of a mechanical failure or malfunction noted.
