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.

PROBABLE CAUSE: "The accident was caused by taking off with no. 4 propeller feathered and with the flaps fully down. In this configuration the takeoff was beyond the same performance capabilities of the aircraft and in consequence adequate control could not be attained."
