What happened
During the flare and touchdown phase near the runway, the aircraft encountered considerable turbulence. The airplane traveled down the runway for a significant distance without landing, at which point the pilot initiated a go-around.
As the aircraft passed the end of the runway, a passenger noted that the tail of the plane felt low and the aircraft appeared to be floating just above the treetops with a wiggling motion. The pilot reported that the airplane would not climb, and the aircraft was barely clearing the trees. During this maneuver, the left wing dipped, causing the aircraft to strike trees before impacting a garage roof.
Prior to the flight, the pilot had informed a passenger that he had never operated the aircraft with a passenger seated in the rear seat, which was the configuration used during this flight.
