Analysis

The pilot and his passenger were on a fishing/sight-seeing flight when they encountered winds estimated at 35 knots blowing over a mountain ridge. The pilot attempted to fly over the ridge but turned away after experiencing a strong down draft. A second attempt was made at approximately 200 feet AGL, but the airplane did not have sufficient altitude to clear the ridge after entering the area of the down draft and crashed on the approach to the ridge.
