A helicopter's main rotor blades were substantially damaged after contacting a power line while maneuvering over a cherry orchard during a drying operation in low light due to cloudy conditions.

Incident Details

A pilot reported that the helicopter was maneuvering at a low altitude over a cherry orchard as part of a drying operation. During the maneuver, the main rotor blades contacted a wire, resulting in substantial damage to the blades.

Weather and Visibility

The light was low due to cloudy weather conditions. The pilot stated that he did not see corroded copper wires that were adjacent to the orchard.

Pilot Report

The pilot noticed a pole that had shiny wires on one side, which gave him the illusion that it was the end of the power line. The other pole connected to the line was obscured by trees and not visible. The pilot reported no pre-impact mechanical malfunctions or failures with the helicopter that would have precluded normal operation.
