What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
During training/evaluational flight, autorotations with power recovery were conducted. Incident of hard landing occurred during autoratation with power recovery when the pilot failed to open throttle during power recovery. Deceleration was completed too high and collective (initial) done outside of normal parameters causing insufficient cushion on ground contact resulting in a hard landing.
