The pilot of a Scheibe SF25E (G-KDEY), was flying a series of circuits and was heading towards the airfield when the aircraft struck the ground in a field west of the airfield boundary, 23 March 2020.

The investigation found that carbon monoxide had been leaking from the exhaust and is likely to have impaired or rendered the pilot unconscious before the aircraft hit the ground.

The report highlights the EASA and CAA guidance on maintenance of piston engine exhaust systems to reduce the risk of carbon monoxide poisoning and the options available in selecting carbon monoxide detectors for General Aviation aircraft. A CAA safety leaflet and EASA report also highlights the issues associated with the use of Mogas and the increased risk of carburettor icing due to the ethanol content.
