On the day of the accident, the pilot took three of her work colleagues on a tour of the mine pits to the North of the camp. When the aircraft returned to the mine's airstrip, the pilot made a low pass over the camp with the canopy fully opened to drop water bombs, before commencing a climbing left turn to rejoin the circuit for a landing. Whilst the aircraft was climbing, the aircraft stalled. The pilot could not regain control before the aircraft collided with the trees. The pilot had been previously instructed not to make low passes over the campsite. The aircraft flight manual indicates that flight with the canopy partly open, but not fully open, is permissible. The effect of a fully opened canopy on the aerodynamics of the aircraft was not determined. The pilot apparently failed to ensure that she maintained a sufficient margin above the stalling speed during the climb out following the pass. This accident was not the subject of an on-scene investigation.
