Robinson R44 II crash near Stoenești, Prahova County, Romania

Positioning back to base at Șirna in deteriorating weather, the pilot chose to make a precautionary landing in a snow-covered field. Rotor downwash lifted large quantities of snow, he lost visual reference with the ground, and the helicopter touched down hard in deep snow and rolled over. The investigation found the cause to be an erroneous assessment of the flight conditions, which delayed the decision to land as visibility fell rapidly.
