Analysis

The plt reported that during flt at 11,300 ft MSL near a 12,516 ft mountain, he saw a herd of elk. He made a left turn to return to the mountain. He said the plane encountered a downdraft that produced a 500 fpm rate of descent. The plt applied full power, but could not stop the descent. He saw a clear area near the 10,000 ft level & elected to land. During the landing, both wings, the fuselage and the landing gear were damaged.
