Bell 206B, N60KH, Kash Helicopter Services LLC: Accident occurred June 30, 2017 in Uniontown, Union County, Kentucky

Aviation Accident Final Report - National Transportation Safety Board: https://app.ntsb.gov/pdf

NTSB Identification: GAA17CA402
14 CFR Part 137: Agricultural
Accident occurred Friday, June 30, 2017 in Uniontown, KY
Probable Cause Approval Date: 11/14/2017
Aircraft: BELL 206, registration: N60KH
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 pilot of the helicopter reported that, while maneuvering low around power lines during an agricultural spray, he “pulled up,” and the right spray boom contacted a power line. He added that the “fuselage pitched forward and the main rotor blade cut the tail boom off just aft of the horizontal stabilizer.” Subsequently, the helicopter began to rapidly spin, and after one or two rotations, the pilot “closed the throttle which stopped the rotation” and “cushioned the impact.” 

The fuselage and tailboom sustained substantial damage.  

The pilot reported that there were 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 as follows:
The pilot's failure to maintain adequate separation from power lines, which resulted in a loss of helicopter control.

Additional Participating Entity:
Federal Aviation Administration / Flight Standards District Office; Louisville, Kentucky
