The airplane was substantially damaged at about 1230 Pacific time when it collided with the ground just off the runways departure end during an attempted go-around. Neither the Private pilot nor the two passengers was injured. Visual conditions prevailed. The pilot subsequently said the airplane was a little high and too fast during the approach, so he elected to go around. After increasing power, the airplane stalled and collided with terrain. The pilot also stated the accident resulted from his pilot error.
