Palo Alto Airport
Aircraft Accident/Incident Report

Palo Alto, California 95148
Wednesday, February 2, 2000 14:37 PST

NTSB Narrative Summary Released at Completion of Accident

The pilot and passenger were inbound to land and the pilot requested permission to perform an autorotation, which was approved. The pilot reported that he did not think he was going to reach the runway during the autorotation so he added power. The engine failed to respond and the tail stinger contacted the ground resulting in the separation of the tail boom. The pilot pulled collective pitch; the helicopter briefly became airborne, and spun violently to the right. The pilot maintained a level attitude and the helicopter landed hard. After the rotor stopped, they exited the helicopter. The pilot stated that he should have used carburetor heat prior to the extended engine idle period of the autorotation. The temperature and dew point were in the serious icing-glide power range.

NTSB Probable Cause Narrative

The pilot's failure to use carburetor heat, resulting in a loss of engine power, and, his misjudged autorotation approach that resulted in a collision with the ground during the landing flare. Contributing to the accident was the conditions conducive to carburetor icing.
