The NTSB's narrative final · quoted from the NTSB record

The pilot was landing the helicopter at a private heliport. The outside air temperature was about -1 degree Celsius (C). After a normal touchdown, the helicopter began to spin and the tail rotor struck a snow bank, which resulted in substantial damage to the tail rotor and lower vertical stabilizer. After exiting the helicopter, the pilot noted that the ground was coated with "black ice." The pilot reported that he did not experience any malfunctions or failures of the helicopter that would have precluded normal operation. He further reported about 635 hours of rotorcraft flight experience, which included 85 hours in the same make and model as the accident helicopter.
