On August 14, 2010, approximately 1100 mountain daylight time, a Shpakow SA 750 bi-plane, N28KT, was substantially damaged when it collided with a radio controlled AJ Slick airplane, while performing a go-around at the Van-Aire Estates Airport, Brighton, Colorado. Visual meteorological conditions prevailed at the time of the accident. The personal flight was being conducted under the provisions of Title 14 Code of Federal Regulations Part 91 without a flight plan. The pilot and his passenger were not injured. The flight departed Centennial Airport, Denver, Colorado, approximately 1030 and was en route to Brighton, Colorado.

According to a video of the accident and multiple witnesses, the radio controlled airplane was maneuvering over runway 12. The bi-plane is seen flying from the north to south in straight and level flight when the radio controlled airplane climbs directly into the bi-planes flight path. The bi-plane was able to land without further incident. An examination of the airplane revealed that the left lower wing spar was crushed aft."
