The commercial pilot was practicing emergency maneuvers in the helicopter. He completed two successful power recovery practice autorotations; however, during the third, the pilot noted a vibration in the rotor during the landing flare. He reported that, when he initiated the power recovery, the engine power “wasn’t there.” The pilot then leveled the helicopter and used the collective to soften the landing. Upon contacting the ground, the skids separated from the helicopter and the helicopter rolled onto its side. Examination of the helicopter and engine at the accident site did not reveal any anomalies that would have precluded normal operation and the reason for the loss of engine power could not be determined.
Probable Cause: A loss of engine power during a practice power recovery autorotation for reasons that could not be determined based on the available information.
