Event ANC22LA023

Factual narrative

The pilot reported that the helicopter was being used to transport skiers in support of a commercial Heli-ski operation when the helicopter inadvertently collided with terrain while maneuvering to land on the glacier. The pilot stated that while on approach to an area to pick up a group of skiers, flat light conditions made it difficult to discern topographical features on the snow-covered, featureless, glacial terrain. The pilot said that during the approach, he inadvertently allowed the helicopter to descend below his intended approach path, and the helicopter touched down short of his intended landing site. The helicopter subsequently rolled to the left and the main rotor blades struck the snow-covered terrain. The helicopter sustained substantial damage to the main rotor blades, tail rotor blades, tail boom, and fuselage. The pilot reported that there were no pre-accident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
