N2266GRobinson Helicopter R66 · 2022

The accident airplane was the second of two airplanes, traveling as a flight of two, en route to a remote wilderness lodge in an area of mountainous terrain. The accident pilot stated that as the flight entered a mountain pass, the two airplanes became separated due to heavy snow showers. He said that visibility deteriorated to a point that it was difficult to discern topographical features while in the pass, and he elected to turn around. The pilot reported that during a descending left turn the airplane collided with an area of snow-covered up-sloping terrain, sustaining substantial damage to the wings, fuselage and empennage. The pilot said there were no preaccident mechanical problems with the airplane and that the airplane was recently equipped with a 406 MHz Emergency Locator Transmitter, which aided rescue crews in finding the accident site quickly.
