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

While demonstrating a low level 180 degree autorotation to a rated pilot, the CFI undershot his intended touchdown point. In an attempt to reach his selected touchdown point, the pilot allowed the rotor RPM to decay and the aircraft developed a high sink rate. The pilot then attempted a power recovery but was late with the corrective action. The aircraft received substantial damage when it contacted the ground and bounced twice before coming to rest on its right side.
