Probable cause
A total loss of engine power due to a loss of cooling oil to the turbine-to-compressor coupling shaft and subsequent fracture of the shaft at an altitude too low for the pilot to complete a successful autorotation. Contributing to the accident was carbon buildup in the piccolo tube screen and nozzles and the disintegration of the spur adapter gearshaft O-rings for reasons that could not be determined.
