Bell 206-L4 N652HA accident near Springfield, Ohio

Probable cause

The pilot’s failure to remain clear of powerlines during an agricultural spraying operation.

NTSB analysis

The commercial pilot was spraying a cornfield on an east-west pattern when he flew through a set of four high-tension powerlines that ran northeast-southwest through the cornfield. The middle two powerline wires were severed, but the top and bottom wires were not damaged. The helicopter came to rest about 150 ft east of the powerlines. A review of ADS-B data revealed that when the pilot arrived at the cornfield, he circled and flew over the powerlines, indicating that he was likely aware the powerlines would be an obstacle during the spray run. He then made several more spraying passes over the powerlines before the data ended shortly before he impacted the wires. On-scene examination of the wreckage revealed all major components of the helicopter were located at the accident site and that there was no evidence of any preimpact mechanical or malfunctions or failures of the helicopter that would have precluded normal operation.
