(.19) On November 21, 2002, at 1640 pacific standard time, an asmus exec 162F experimental helicopter, N162LC, rolled over during an autorotative emergency landing on the beach in Monterey, California. The pilot operated the helicopter under the provisions of 14 CFR part 91 for the local area personal flight. The helicopter sustained substantial damage; the pilot, the sole occupant, was not injured. Visual meteorological conditions prevailed and no flight plan had been filed. The flight departed marina municipal airport (oar) at an unknown time. The federal aviation administration inspector interviewed the pilot. The pilot reported that the engine quit during cruise flight approximately 600 to 700 feet above ground level (AGL). The pilot initiated an autorotation and during the descent power was restored; consequently, the helicopter yawed to the left. The pilot closed the throttle and the helicopter rolled over as it made contact with the ground. (-23) the pilot stated that while he was in cruise flight at 600 to 700 feet AGL, the engine seemed to quit. He initiated an autorotation and on the way down, the engine suddenly came back to full flight RPM. When this happen ed, there was a tremendous amount of yaw and he elected to close the throttle. By the time he had done that, it was not time to land. Having never performed an autorotation to the ground, the pilot said he did the best he knew how on the landing. The helicopter hit the ground in a tail low, slight left turning attitude.
