While there are differing statistics regarding causes of aircraft fire-related accidents, it is safe to say that aircraft maintenance and pre-flight actions by the pilot play a significant role in most such events. And since the chances of surviving an in-flight fire without major injury or death are poor, preventing a fire from occurring in the first place should be Job One. Pilots can memorize procedures, talk about scenarios and what-ifs, but when it is all said and done, avoiding one starts on the ground.
Of course, fires require three key ingredients: heat or an ignition source, fuel or material that will burn, and oxygen (air). It so happens aircraft are operated hundreds of hours with these three key ingredients in close proximity. Thankfully, and due to careful design and maintenance practices, fires rarely occur. But seemingly minor details can be overlooked and introduce a chain of events that can cause an in-flight fire.
