Connetts Farm founder Nick Stevens confirmed the small aircraft crashed on the farm.
Stevens said he was working nearby when he saw a “serious fire” on the farm which he thought was one of his barns, but when he arrived he discovered it was the light aircraft.
Emergency services had already been informed when he arrived at the scene and he said road closures were in place in the area.
The Dunkeswell Aerodrome is a former RAF site located in the Blackdown Hills area of Devon, close to the county’s border with Somerset.
According to the aerodrome’s website, the site was originally built to be a US naval base during World War Two.
It is also claimed to be the highest licensed airfield in the UK.
One witness called Johnny, who was on Marcus Road, which is south of the airfield, said he saw “a lot of black smoke” east of the airfield at about 11:00.
