Probable cause
The loss of engine power as a result of fatigue cracking of the compressor adaptor coupling initiated by fretting on the pilot diameter and subsequent disconnection of the compressor from the turbine assembly. A contributing factor was the low operating altitude of the helicopter, which made a successful autorotation by the pilot imposible.
