Cessna A188B-A1, VH-FZD, 6 km SE of Kingaroy QLD, 14 December 1984

As part of the final phase of the rating test, the pilot was required to spray a paddock. An inspection of the area to be treated was carried out. During the procedure turn at the end of the second spray run, the nose dropped and the aircraft struck the ground in a near vertical attitude. The pilot had incorrectly assessed the wind direction and had carried out the procedure turns at the end of the spray runs in the wrong direction. In an effort to align the aircraft for the next run, the pilot tightened the turn and the aircraft stalled.
