What happened
During the initial climb phase following departure, the aircraft's left engine ceased functioning. In response to the mechanical failure, the crew performed the procedure to feather the propeller and initiated an emergency return to the airfield.
While the aircraft was executing a left-hand turn to reposition for landing, it entered a stall condition. The plane subsequently impacted a rice paddy field. There were 15 fatalities among the occupants of the aircraft.
Findings
Investigation into the accident determined that the primary factor was the failure of the left engine during the climb following takeoff.
