HISTORY OF FLIGHTOn September 11, 2013, about 1155 mountain daylight time, a single-engine experimental Kamtz Vans RV-7A, N820RV, experienced a loss of power and departed control flight while the pilot was maneuvering in the traffic pattern at the Jackson Hole Airport, Jackson Hole, Wyoming. The private pilot and passenger were fatally injured. The airplane was registered to and being operated by the pilot under the provisions of 14 Code of Federal Regulations Part 91.

Also causal was the pilot’s failure to adequately compensate for the wind conditions, which resulted in his failure to maintain adequate airspeed and his subsequent loss of airplane control while maneuvering wit
