NTSB investigators used data provided by various entities, including, but not limited to, the Federal Aviation Administration and/or the operator and did not travel in support of this investigation to prepare this aircraft accident report.

According to the pilot, during an aerial application flight, the helicopter pilot was flying between 6 and 7 feet above the ground, at an airspeed of 20 knots. While maneuvering, the pilot encountered a low rotor rpm situation and the helicopter started to settle. As soon as the helicopter descended, the landing skid became tangled in the rice plants, and the helicopter came to rest on its side. During the collision with terrain, the tail boom and main rotor separated from the fuselage. An examination of the helicopter and its systems revealed no preimpact mechanical failures or malfunctions.

The National Transportation Safety Board determines the probable cause(s) of this accident to be:

The pilot's failure to maintain adequate rotor rpm during a low-altitude maneuvering flight.
