Loss of control and collision with terrain, Cessna 150, VH-RXU 270 km SE Alice Springs, Northern Territory, on 12 July 2016

Turning manoeuvres at or close to the aircraft’s critical angle of attack, if mishandled, can lead to a stall that may result in the aircraft entering a spin. Recovery from this condition will take a considerable amount of altitude, dependant on the speed of response by the pilot and the use of appropriate control inputs.
