What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot in command/flight instructor was conducting helicopter refresher training for the second pilot at orlando/Apopka airport. The second pilot was the "pilot flying." During a practice autorotation from altitude, the second pilot got too low prior to flaring. The flight instructor could not get on the controls in time to prevent the subsequent damage to the tail rotor guard (stinger or tail skid) and the tips of the tail rotor blades. The damages were minor.
