The accident flight was a continuation of training that had started with a flight that morning. About ten to fifteen minutes after take-off the owner/pilot noticed that the left-hand exhaust gas temperature gauge was falling towards zero. He immediately turned the aircraft towards the airfield and informed his passenger, who was an experienced pilot. The aircraft continued towards the airfield for about ten to fifteen seconds when the engine stopped. The owner/pilot handed control of the aircraft to his passenger as he had more recent flying practice. The passenger immediately turned the aircraft into wind and aimed towards a field that was in front of the aircraft. This was the only large field within gliding range that did not contain livestock. The glide approach was progressing very well until the aircraft was about 20 to 30 feet from the field boundary when an area of descending air was encountered. This resulted in the aircraft colliding with field’s boundary hedgerow rather than flying over it. A meteorological aftercast strongly suggested that carburettor icing was the possible cause of the engine failure.
