Description
Shortly after takeoff for a flight to Dagura, the Twin Otter crashed out of control in a steep dive in shallow water, 2 km from the runway. An investigation by the Australian Bureau of Air Safety Investigations revealed an explosion and fire occurred shortly after takeoff, causing the electrical system to fail. The fire’s source probably was the terminal board between the inverters and control relay. Kerosene carried in passenger luggage in the Twin Otter’s aft cargo hold possibly began leaking and was possibly ignited by faulty or age-deteriorated electrical wiring.
Primary Cause
Faulty electrical wiring and aging terminal board failure caused by leaking kerosene.Faulty electrical wiring and aging terminal board failure caused by leaking kerosene.Share on:
