Aircraft involved

Probable cause & findings

Improper control inputs by the pilot-receiving-instruction and the inability of the flight instructor to correct the control inputs in sufficient time to avoid the hard landing.

Factual narrative

The pilot-receiving-instruction was demonstrating a 180-degree autorotation at the time of the accident. He inadvertently overshot the intended ground target point. After rolling out of the turn, the pilot-receiving-instruction did not flare properly and, instead, increased collective until reaching the control stop resulting in a loss of main rotor speed. The flight instructor was unable to correct the pilot’s control inputs in time to prevent a hard landing. The landing skids collapsed, and the helicopter sustained substantial damage to the tail boom and fuselage. The flight instructor and pilot-receiving-instruction reported no preimpact mechanical malfunctions or failures associated with the helicopter.
