Narrative:
The helicopter was engaged in an aerial survey of Central Electric's distribution system. The pilot and technician conducting the survey, which utilised GPS equipment to pinpoint individual power pole positions, were accompanied by a line surveyor from the local electrical supply authority who acted as a guide and supplementary lookout. During the course of mapping a roadside 11kV line, the helicopter collided with the Roxburgh-Islington A 220kV line. The reactive forces of the rotor strike tore the transmission and engine from the airframe. The fuselage section of the helicopter came to rest inverted. The surveyor died in the impact sequence. The pilot and technician received serious injuries.
