What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) This was a dual instruction part 61 training flight to add a rotorcraft rating to an existing private pilot certificate. On a practice hovering autorotation, with the student flying and the instructor "following along" on the controls, the left skid hit the ground and dug into the soft earth. The aircraft proceeded to roll onto its left side, at which point the main rotor blades contacted the earth. The instruction was taking place in a grassy area between the runway and the taxiway, without nearby obstructions. Weather was not a factor, being clear with the wind reported to be light and variable at the time of the incident.
