Runway excursion involving a Cessna Aircraft Company 172N, VH-WNN, Parafield, Aerodrome, SA on 8 July 1995

The student pilot, who had very limited flying experience, was on his third solo training circuit for the flight when the accident occurred. The aircraft was in the ground-run phase of a touch-and-go landing when it began to veer to the left. The pilot applied opposite rudder, in an attempt to correct the situation, with no apparent effect. Realising that the aircraft would run off the strip the pilot closed the throttle and applied the brakes. However, the aircraft ran into a ditch, damaging the propeller and nosewheel leg before it stopped moving. The student pilot had completed three successful dual circuits prior to commencing solo training.
