The pilot first obtained a private pilot licence in April, 1966 but, because he had not completed a course of navigation flying training, his licence was valid only for flight within five miles of any departure aerodrome or within the confines of a flying training area. He was not qualified to fly in other than visual meteorological conditions. The aircraft was normally based in a hangar on the pilot's property near Bylands and fuelled from drums stored in the hangar. An examination of the wreckage indicated that the aircraft had struck the ground in a steep spiral dive. No evidence was found of any defect which may have contributed to the accident. There was only a small amount of fuel remaining in the tanks but fuel may have drained away through broken lines after the accident.

The cause of this accident has not been established but it is apparent that the pilot attempted the flight in weather conditions which were unsuitable and this may have led to the loss of control.
