The pilot was attempting to land in a 20 knot right crosswind with gusts to about 25 knots. According to the P.O.H. the airplanes demonstrated crosswind component is 13 knots. The pilot initiated a go around and during the initial climb the pilot turned a close left crosswind giving the airplane a 20 knot plus direct tailwind. Witnesses said the aircraft never got above 100 feet, and, after narrowly missing a water tank, it suddenly banked 90 degrees to the left and fell to the ground. Witnesses stated that the airplane was very low with positive engine power. According to local area pilots, under the wind conditions on the day of the accident the area just southwest of the airport is capable of severe turbulence, wind shears and down drafts associated with a southwesterly air flow over and between Mount Haney and Saddle Mountain. Weight and balance computations were performed using three different fuel loads and other estimated weights. All three calculations put the center of gravity at the forward C.G. limits. During the on scene accident investigation a lubricant container was found in the tail cone area. A close examination of the area revealed evidence of can contact and rubbing on the stabilator servo tab rod. The rod was found bent.
