Analysis

The pilot started to air taxi the helicopter out of a hangar. There was snow in front of the hangar that had been only partially cleared away. As the pilot was exiting the hangar, he raised the aircraft to go over the snow, the tail rotor struck the hangar door, and a hard landing followed.
