The NTSB's narrative final · quoted from the NTSB record

The non-certificated pilot was flying an unregistered experimental, amateur-built airplane. The husband of the pilot informed a Federal Aviation Administration (FAA) inspector that his wife departed from a pond covered with ice. His wife flew around the local area, just above the trees, at 200 feet. The airplane was heading towards a housing area and pulled up just before it collided with the roof of a private residence. The airplane glanced off the roof, hit another residence, and came to rest on the ground inverted. The pilot informed her husband that the rudder on the airplane was stuck. Examination of the airplane by the FAA inspector revealed no anomalies with the airplane.
