The NTSB's narrative final · quoted from the NTSB record

The flight instructor reported that she provided takeoff and landing training from and to a helicopter landing platform. During landing, the student pilot had control of the collective and the antitorque pedals, and the instructor maintained control of the cyclic. The instructor added that, during landing on the platform, "the student lowered the collective suddenly, and also pulled back up (on the collective) suddenly." Additionally, the student grabbed the cyclic and pulled aft when he increased the collective. The helicopter bounced on the platform and tilted backward. The helicopter rolled onto its right side, the instructor closed the throttle, and the main rotor blades struck the ground. The helicopter sustained substantial damage to the main and tail rotor drive systems and the fuselage. The instructor reported that there were no preaccident mechanical failures or malfunctions with the helicopter that would have precluded normal operation.
