What happened
The FAA’s narrative, in sentence case. The FAA writes it in capitals and removes private details.
The pilot was applying chemicals to a corn field parallel to a powerline. Approaching an intersecting powerline, the pilot pulled up to turn when his right spray boom contacted the intersecting wire. Upon contact with the wire, the fuselage pitched, causing the main rotor blade to cut the tail boom off just aft of the horizontal stabilizer. The aircraft spun rapidly one to two times before the pilot closed the throttle, which stopped the spinning. The pilot cushioned the landing by using the remaining collective pitch, and came to rest level in the corn field.
