Loss of control involving a Cessna Aircraft Company 172N, VH-TKJ, Archerfield, Aerodrome, QLD on 30 July 1995

The pilot reported that he had completed two touch-and-go landings on runway 22 left and had been cleared for a touch-and-go on runway 22 right which had a displaced threshold. The approach, which was being flown with 20 degrees flap and about 1500 rpm engine power, was shallower than the earlier approaches. The pilot said that, about two metres above the ground, as he was about to increase power slightly to ensure that the aircraft did not touch down before the displaced threshold, the nose dropped. The nosewheel struck the ground firmly and the aircraft nosed over. The pilot could not recall hearing the stall warning sound during the approach, although it had tested serviceable before the flight.
