NTSB summary
HISTORY OF FLIGHT On September 12, 2004, about 1320 central daylight time, an un-registered amateur-built Claxton S-12, piloted by a non-certificated pilot, was destroyed when it impacted the ground near Oconomowoc, Wisconsin. The airplane was previously registered as N82000. The 14 CFR Part 91 personal flight was operating in visual meteorological conditions without a flight plan. The pilot, who was the sole occupant, was fatally injured. The flight had just departed from a private airstrip, and was en route to the Sylvania Airport, Sturtevant, Wisconsin. According to another pilot, he and the accident pilot departed from the private airstrip as a flight of 2 aircraft. He stated that he departed first and continued to the destination. This pilot reported that he was unaware that the accident had occurred until after he had completed the flight. A witness that lived near the accident site reported seeing an ultralight type airplane fly over his residence. He stated that a second ultralight airplane was about 1/2 mile behind the first one. He stated that the second airplane was flying south over highway P and he heard the engine "quit". He stated that there was no engine sound and that the airplane made a left turn to the east with not much change in altitude. He said that the airplane headed east for about 100 yards and then made another left turn to the north. At this time, the airplane was starting to lose altitude. The witness stated that he was concerned for his safety since the airplane was heading toward him so he took cover behind a large tree. He said that he heard
Probable cause
The loss of engine power due to the seizure of the pistons and the pilot's failure to maintain airspeed which resulted in an inadvertent stall. The previous damage to the pistons due to earlier seizure occurrences was a factor.
