Intermountain Callair A9A, VH-MPB, Kondu WA, 8 August 1969

196904741

Summary

After receiving a sketch plan of the area to be sprayed, the pilot made an aerial inspection and noted the position of power lines. He then made nine spraying runs which involved pulling up over a power line which crossed the paddock approximately one third of the distance along the spray runs. On the tenth spray run the pilot allowed his attention to be temporarily distracted through watching a marker change to a corrected position. When he again gave his attention to the flight path he became aware that the power line was immediately ahead and at the same height as the aircraft. He attempted to climb the aircraft, but the wires became hooked on the tail wheel assembly. The aircraft decelerated rapidly and contacted the ground on the port main wheel and wingtip. The power lines did not break, but three of the wooden supporting poles were pulled to the ground.
