After a normal landing on grass Runway 24, the aircraft veered left and departed the runway surface. The left main landing gear entered an area of soft ground and the aircraft ground-looped to the left through 180°. During the ground loop, the landing gear collapsed.
The surface wind at Netherthorpe was not reported but Doncaster Sheffield Airport, 12 nm to the north-east, reported the surface wind at the time as being from 220° at 5 kt. The pilot considered that a possible gust of wind, with a slight tailwind component, may have been a factor in the accident.
