Narrative:Prior to flight, the pilot checked the weather and also received a weather briefing from a Flight Service Station. The briefing revealed high winds and mountain obscuration along his route of flight. In order to avoid the adverse weather, the pilot departed on a westerly heading and climbed to 12,500 feet rather than his usual altitude of 8,500 feet, on a northwesterly heading across mountainous terrain. Thirty minutes into the flight he encountered strong downdrafts and wind shear on the lee side of the mountains. He applied full power, and initiated a 180-degree turn but was unable to maintain altitude. The airplane descended into a cloud layer, and continued to experience severe turbulence; the airplane subsequently stalled and entered a spin. The pilot recovered from the spin momentarily, before the airplane again stalled and entered a second spin. The airplane then exited the clouds at approximately 500 feet agl. The pilot then force landed the airplane into rising terrain.
Probable Cause: The pilot's inadequate preflight planning/preparation and attempted flight into known adverse weather during cruise, and his failure to maintain an adequate airspeed margin that resulted in a stall/spin. Turbulence was a factor.
