The NTSB's narrative final · quoted from the NTSB record

According to the pilot, during an aerial application flight, he initiated a climbing turn, which he thought did not "feel right." He leveled the helicopter, stopped the turn, lowered the collective and added full throttle. The pilot stated that the rpm indication was in the bottom of the green arc. The helicopter began losing altitude and impacted a cornfield. The pilot indicated that there were no mechanical malfunctions with the helicopter. The helicopter sustained substantial damage when the main rotor separated a section of its tailboom.
