The private pilot of the personal flight stated that he did not feel comfortable continuing the approach for landing at the destination airport, so he initiated a go-around. During the go-around, the airplane was too slow, and the pilot said he heard the stall warning horn. The airplane then stalled and impacted terrain. The airplane was destroyed by impact forces. Postaccident examination of the airplane flight control system confirmed flight control continuity. A National Transportation Safety Board Pilot/Operator Aircraft Accident/Incident Report was not received from the pilot.
