What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
While conducting flight training, flight instructor stated he was demonstrating a simulated engine failure on takeoff. During acceleration on taxiway e at around 10-15 feet AGL the helicopter experienced a sudden loss of altitude, subsequently contacting the ground hard on the aft portion of the skids bouncing foward and aft several times on the ground which resulted in a ground run of approximately 370 feet, then aircraft suddenly yawed 180 degrees to the right immediately followed by another 180 degree yaw to the left before coming to a complete stop. The helicopter remained on the ground for about one minute with engine and rotor operating. Pilot, then, picked up the aircraft to a hover and made a 180 degree left pedal turn, then accelerated down the same taxiway and executed what appears to be another running landing to a full stop, remained on the ground for about 30-40 seconds, then taxied to parking area.
