NTSB investigators either traveled in support of this investigation or conducted a significant amount of investigative work without any travel, and used data obtained from various sources to prepare this aircraft accident report.
The helicopter had completed aerial applications at two designated locations without incident. Recorded GPS data and witness information indicated that the helicopter then travelled north at a low altitude to another location. Witnesses observed the helicopter rolling or banking left and descending. The helicopter subsequently impacted a residential garage and terrain. A postimpact fire destroyed the helicopter’s forward section and a majority of its control system components. An examination of the helicopter and its systems revealed no malfunctions or failures that would have precluded normal operations. The helicopter was below the allowable maximum gross weight. The reason of the loss of helicopter control could not be determined.
