Witnesses described an "enormous explosion" as the helicopter crashed in a crop field at Aldborough near Boroughbridge at about 1.30pm yesterday.
Its officers were working alongside investigators from the Civil Aviation Authority, which will examine the cause of the crash.
"One man, believed to be the pilot of the private aircraft, was pronounced dead at the scene. No further casualties have been reported.
"Clearly this is a tragic event and thoughts are very much with his family and friends. No further information is available at the present time."
Mr Dodd was also a former chairman of York, North Yorkshire and East Riding Local Enterprise Partnership.
