The NTSB's narrative final · quoted from the NTSB record
The pilot said that he was using an aerial saw to side trim trees along a powerline right-of-way. The pilot said, "At the end of the tree line at approximately 150' (feet) agl (above ground level) I applied power to climb, immediately the low rotor rpm horn sounded. I tried to increase N2/Nr (engine and rotor rpm) with the governor 'beep switch' and checked N2/Nr. There was no response from trying to increase N2/Nr and N2/Nr was in the low 90's. I lowered the collective, released the saw and radioed my ground crew that the engine had stopped. At this point I had low airspeed, low N2/Nr and approximately 100' agl. I aimed the aircraft at an open field and tried to gain airspeed to attempt a running landing." The pilot said the helicopter "impacted the field in a near horizontal attitude." An examination of the helicopter at the accident site showed the helicopter resting on its left side in a corn stubble field approximately 300 feet south of east-west running power lines, and approximately 730 feet from a clearway of trees where the helicopter was cutting prior to the accident. An examination of the helicopter revealed no anomalies.
