What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
Pilot who was seriously injured does not remember the events of the accident. A witness stated that he observed the helicopter maneuvering near the area of the windsock but could not tell from the distance he was at if the helicopter was maneuvering over the paved runway or on the grass. He observed the helicopter wildly rotate left and right and spin completely around either one or two full revolutions, he then observed the helicopter climb and then stated that the tail went almost vertical and the helicopter crashed to the ground.
