The Federal Aviation Administration said the pilot was killed when a plane crashed into a yard along Eagle Lake in Kansasville in southeastern Wisconsin.
FAA spokesman Tony Molinaro said the single-engine Beechcraft Bonanza was flying from Chicago Executive Airport to Minocqua in north-central Wisconsin when it crashed and hit a building around noon Sunday.
He said the pilot, who was the only person on board, was killed and the plane was destroyed, but no injuries on the ground were reported.
Molinaro said the cause of the crash is unknown, but the FAA and the National Transportation Safety Board will investigate.
The pilot's name has not been released.
Witnesses reported hearing the plane flying low and then a loud boom. They described seeing the plane, cars, sheds, and trees on fire.
