Narrative:The Heron was being used to conduct a crew training flight. An approach was made with a simulated no. 4 engine failure and flaps fully down. After touchdown power was increased and the aircraft took off again, flying very low and at a slow speed. It then struck trees near the airport boundary, struck the roof of a house, rolled on its back and crashed into dense woodland.
