Narrative:The pilot reported that he was starting his 27th move of geophysical drilling equipment for the day. He was pulling in power to lift (long line) an engine and a compressor when he heard two loud "pops." He lost engine power, but did not release the long line because his ground helper was underneath the load. He moved forward a short distance, and autorotated to a 45 degree hill side. The aircraft landed and immediately rolled on its side with the mast pointing down slope which stopped the rolling. The ground helper said that he saw "fire shooting out of the tailpipe" as the helicopter descended towards the earth. Postaccident examination of the engine revealed that all the turbine blades had experienced an extreme over temperature condition. The density altitude was computed to be 9,205 feet.
Probable Cause: the failure of the turbine assembly due to an over temperature condition. A contributing factor was the lack of suitable terrain for a forced landing.
