Collision with terrain involving a Cessna A188B/A1, VH-IBT, 10 km east of Murrurundi, New South Wales, on 23 May 1994

The aircraft was engaged in spreading Gypsum from an airstrip with an elevation of 3,200 ft. Take-offs and landings were conducted towards the west, with the wind varying from the northwest to the southwest and increasing in strength. The pilot reported he had encountered high sink rates and turbulence in the treatment area on previous flights.

Acceleration and lift off during the next take off appeared normal but the aircraft almost immediately began to sink. The pilot lowered the nose and activated the load dump system. However, the sink could not be arrested, and the aircraft collided with a fence. The engine and both wings were torn off.
