What happened
The incident occurred during a routine local training exercise in the vicinity of RAF Wittering. The aircraft, piloted by a single individual, was engaged in aerobatic maneuvers when the pilot entered an inverted flight attitude. During this specific phase of the maneuver, the pilot lost control of the airframe. Unable to recover from the unstable condition, the aircraft descended and impacted the ground near the airfield perimeter.
Findings
The loss of control occurred specifically while the aircraft was in an inverted position. As the sole occupant on board, the pilot did not survive the impact. No other persons were present in the aircraft at the time of the accident.
