What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot flew the helicopter into heavy snow, low ceilings and forward visibility. Due to the flight conditions the pilot stated he had descended to a lower altitude. The pilot stated that he had an engine-out indication, and entered an auto-rotation in to a nearby farm field. Upon reaching the ground , the pilot held the cyclic full aft, causing the tail skid to contact the ground which broke the tailboom upward into the rotating main rotor blades. The aircraft remained upright on its skids, and no one was injured.
