Phase of flight
Which phase of flight each accident occurred in, as coded by the NTSB. Most accidents happen in the phases where most flying time is concentrated, so this isn't a measure of which phase is most dangerous.
Finding category
Top-level NTSB cause category, from the coded investigation findings. An accident often has more than one finding, so totals here can exceed the recorded accident count.
Injury severity
NTSB classification of the worst injury in each accident: None, Minor, Serious, or Fatal. Each accident counts in exactly one severity.
