An aerobatics pilot, who died when his plane crashed at a Norfolk airfield, was suffering from an "undiagnosed heart condition", investigators reveal.
David Jenkins, 61, of Stanton, near Bury St Edmunds, Suffolk, died when his Edge 360 plane crashed at the Old Buckenham airfield on 22 April 2015.
The Air Accidents Investigation Branch report says there was no mechanical fault with the aircraft.
It adds Mr. Jenkins had a "serious" undetected heart condition.
This may have made him lose control of the plane at "critical stage of the flight".
Mr. Jenkins was flying the plane as part of a press day for an airshow.
It adds: "The pilot made no apparent attempt to recover from the spin and suffered fatal injuries in the ground impact."
At the time of the crash, Mr. Jenkins was described by fellow pilots as "highly skilled".
Oxford-educated Mr. Jenkins had twice held the British advanced aerobatics title.
His wife Elaine said it was "with great sadness we wish a husband, a father, a son, a brother and a friend fair winds and blue skies".
Mr. Jenkins had been flying since he was a teenager.
He was a member of the Wildcat Aerobatic Team, based at Old Buckenham Airfield, near Attleborough, where the event took place.
