Aviation Accident Factual Report - National Transportation Safety Board:

Investigation Docket - National Transportation Safety Board:

Federal Aviation Administration / Flight Standards District Office; Louisville, Kentucky

Forming Agrotors Inc:

NTSB Identification: GAA17CA393
14 CFR Part 137: Agricultural
Accident occurred Thursday, July 06, 2017 in Dixon, KY
Aircraft: BELL 206, registration: N8159J
Injuries: 1 Uninjured.

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 helicopter pilot reported that he was maneuvering at low altitude during an agricultural application flight.

While in a left turn he did not see the power line wires until they were very close. He increased the collective to climb and he banked right to avoid impact. However, the tail rotor struck the power line wires and the helicopter lost tail rotor effectiveness. 

The pilot autorotated and the helicopter landed, but the tailboom impacted trees. The helicopter sustained substantial damage to the tail rotor gear box, the tail rotor blades and the vertical stabilizer.

The pilot reported that there were no preaccident mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
