On Saturday 29 January 2005, at 1149, Scott Air Cessna 172 ZK-LLB was on a Police cannabis plantation spotting operation from Queenstown, when it collided with the valley side in Doolans Creek Valley 7 km south of Gibbston. The pilot and Police observer were killed and the aircraft was destroyed.
While circling in a confined mountainous valley the aircraft was briefly descended to a low altitude which did not conserve adequate manoeuvring margins from the valley sides. A further more rapid descent led to the aircraft colliding with the valley side in controlled flight. The cause of this further descent was not determined.
