Blanik L13, VH-GAQ, Northam Airfield WA, 28 September 1988

The aircraft was attempting a take off from Northam Airfield at the time of the accident. The student pilot was flying the aircraft and another student was acting as wingtip walker. The wingtip walker inadvertently held the left wing up against aileron control input from the pilot. When the wingtip walker released the wing, the aircraft rolled rapidly to the left. The wingtip, which was fitted with a combination metal tie-down point and skid, collided with the ground, the skid dug in and the aircraft ground looped. This accident was not the subject of an on-site investigation.
