Occurrence Categories
The most commonly applied occurrence categories for worldwide fatal accidents are shown in Figure 4. Al‑
though these show the types of fatal accident that occur worldwide, more than one category can be applied to
each occurrence and the categories are a mix of causes, events and outcomes. It is therefore unsurprising that
post‑crash fire is the most commonly applied fatal accident category, since in a serious accident a fire is likely to
break out after impact.
Loss of control in flight is the second most commonly applied fatal accident category. This is where the flight
crew lose control of an otherwise controllable aircraft. However, these events tend to occur during complex
high‑workload situations such as those following a technical failure or in extreme weather. The causes of loss of
control in flight for European operators are analysed in detail in the commercial air transport chapter.
