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.

The pilot reported that, after takeoff for the aerial application flight, he made a standard turn to line up with the field to be sprayed and began to descend to fly under two sets of powerlines. He then observed a telephone pole to the right and thought he had plenty of clearance to avoid it. He then heard and felt the impact of a main rotor blade strike the pole. The helicopter yawed to the right before it impacted the ground, rolled forward, and came to rest on its left side. The helicopter was destroyed. The pilot reported no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.

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

The pilot’s failure to maintain clearance with a telephone pole during a low-level maneuver.
