Analysis

The pilot reported that while "hot loading" the second set of fishermen onto the helicopter, one of the fishing rods went into the main rotor disc. The pilot heard a "small tick" but felt nothing on the controls. He hovered the helicopter and no unusual indications were felt through the flight controls.

Upon examination after shutdown, the pilot discovered damage to the main rotor blade and based on the manufacturer's main rotor blade damage guidance, the main rotor blade was found beyond repair limits.

The helicopter sustained substantial damage to the main rotor blade.

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