The pilot took off downhill and to the northeast with a left quartering tail wind from the southwest of approximately 5-8 knots. Shortly thereafter the aircraft crossed over a bluff where the terrain dropped off, and passed over an area populated with deciduous trees. The aircraft began to settle and the pilot executed a left turn toward the west. Just after the aircraft cleared the tree line, it impacted the ground left wing and nose low, coming to rest 49 feet beyond the initial ground impact point. A post crash fire developed and the pilot and his wife exited with minor injuries.
