What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
(-23) According to the CFI, his instructor student entered autorotation with intention of touching down on cfi's private property. It became apparent that they would not clear a tree line and reach the landing area due to strong winds, so the CFI attempted to recover with power. However, he was unable to overcome his student's grip on the throttle. The CFI applied some collective to extend the glide and clear the tree line; however, there was little energy remaining in the main rotor system, and the helicopter firmly contacted the ground, bounced forward, the main rotors drooped and struck the tail boom, and the aircraft rolled onto its side.
