NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

The private pilot had completed a short cross-country Title 14, CFR Part 91 personal flight and was landing her helicopter at a designated helicopter parking area at a tower controlled airport. She stated that she made two passes over the proposed landing area, and noted that it looked very icy and slick. She did not see any other suitable landing area in the immediate vicinity, and elected to land about 50 feet from another helicopter. Upon landing, she said her helicopter began to slide on the icy surface, skidding in a circular fashion towards a parked and unoccupied helicopter. Her helicopter collided with the parked helicopter before she could stop the main rotor blades, resulting in substantial damage to her helicopter's main rotor blades.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's decision to land the helicopter on an icy airport parking ramp, which resulted in a loss of control on touchdown, and subsequent collision with another parked and unoccupied helicopter.
