Probable cause

Compensation for wind conditions was not attained by the pilot resulting in loss of directional control. A factor related to the accident was a gusty crosswind landing environment.

Analysis

The pilot said that he was executing a 360 degree turn while hover/taxiing. The aircraft abruptly whipped around its axis of rotation, in the gusty crosswind environment. The helicopter began uncontrolled oscillations and struck the ground with a rearward momentum. The tail cone hit the ground and collapsed, causing the main rotor blades to hit the ground repeatedly before coming to a stop.
