Sequence of events
NTSB’s coding before 2008: each occurrence and phase of flight, and the causes and factors under it. The codes are defined in NTSB’s coding manual.
Analysis
The plt was practicing power recovery autorotations then attempted one power off, full stop. The plt allowed the main rotor RPM to decay during approach and took no corrective action. The acft landed hard with slight forward motion and the plt applied aft cyclic. The main rotor struck the tail boom and the acft rolled over on its right side.
