Analysis

During initial climb the powered-parachute experienced an unexplained loss of altitude as it passed over a tree line that bordered the hayfield used for the takeoff. The airframe was substantially damaged as it impacted trees and the roof of an occupied residence and fell to the ground. No one on the ground was injured. According to the pilot there were no preimpact mechanical anomalies with the powered parachute and the engine produced full power throughout the event.
