Investigating agency: AAIB
The pilot, who owned G-BUDW, was planning a short flight to test a modification to the aircraft’s fuel system. As the aircraft took off a witness heard the engine running roughly before it disappeared from view. The accident site was found approximately one hour later to the north of the runway. It is likely the pilot had attempted to fly a circuit to land back at the airfield.

Damage sustained to airframe: Per the above AAIB report "aircraft destroyed"). As a result, the registration G-BUDW was cancelled (de-registered) by the CAA on 8 July 2020 as "destroyed" and "Addressee Status: Deceased" (the pilot fatality was also the registered owner/operator)

AAIB Conclusion
The aircraft suffered a partial engine failure shortly after taking off. The evidence suggests that the pilot flew a circuit to the north of the airfield attempting to return to the runway but struck the ground just to the north of the runway.

The investigation found the engine was in poor condition with several defects which could explain the loss of engine power. This included a crack in the head of cylinder 2 and a leak in the manifold.

The pilot had made several modifications to the fuel system, but no evidence was found that these had been approved in accordance with LAA requirements. No evidence was found of on-condition engine health monitoring or an established maintenance schedule for the aircraft.
