Incident Overview
A helicopter crashed and burned after its main rotor struck a powerline pole during an aerial dusting operation over a grape vineyard. The pilot was conducting a swath run when the aircraft gradually converged on a powerline that crossed the field at a slight angle to the flight path. As the helicopter proceeded along the swath, it moved closer to the powerline poles, eventually resulting in the main rotor contacting a pole.
Sequence of Events
The pilot was engaged in an aerial dusting application over a vineyard. While flying a swath run, the helicopter's trajectory brought it progressively nearer to a powerline that intersected the field at a shallow angle relative to the direction of flight. The aircraft continued along its course, and the clearance between the helicopter and the powerline poles diminished until the main rotor blades struck one of the poles. The impact caused the helicopter to crash and subsequently ignite.
Injuries and Damage
The pilot was hospitalized with severe burns on his hands and chest. The helicopter was destroyed by the crash and fire.
Investigation
The investigation focused on the circumstances of the accident. No additional details regarding the helicopter's type, registration, or operator were provided. The official source does not specify a probable cause for the accident.
