The pilot was on a training flight and attempting a dummy landing on a field near Edlington in bad visibility as part of this. As he attempted to apply power to both engines to climb away from this dummy landing the starboard engine failed due to lack of fuel, the aircraft swung because of the power being applied only to the port side engine. The pilot attempted to land in the next field but struck a tree after undershooting the field and crashed near Clifton, close to Edlington.
