NTSB Narrative Summary Released at Completion of Accident

While maneuvering during an aerial application, the helicopter pilot reported hearing a "CA-BANG" sound followed by a loss of pitch control. The pilot was unable to control the helicopter's rate of descent during the emergency landing and hence impacted on sandy terrain and nosed over. An examination of the wreckage showed no anomalies.

NTSB Probable Cause Narrative

The loss of helicopter pitch control for undetermined reasons during the aerial application maneuver and the pilot's inability to control the aircraft during the descent.. A contributing factor to the accident was the soft terrain.
