What happened
On a local test flight departing from Oberpfaffenhofen Airport at 17:27 local time, a twin-engine aircraft carrying one pilot and two inspectors representing the UK Civil Aviation Authority (CAA) crashed into a wooded area. The mission was being conducted as part of an ongoing certification program for the aircraft type.
During the flight, the aircraft transitioned into a nose-down attitude before plunging into the ground. The impact resulted in the total destruction of the airplane and caused three fatalities among the occupants.
Findings
Investigations into the accident indicate that the loss of control was triggered after the crew selected nose-down trim.
