Bell Helicopter Textron 206B

Within its peer cohort

Within this model's peer class (same aircraft type, engine class, and seat range), comparison of its share of recorded NTSB accidents to its share of FAA registration exposure (aircraft-years since 2008).

This is a share comparison, not flight-hours adjusted, so a model flown more per airframe than its peers will show an accident share above its exposure share even if its per-hour safety is average. Methodology →

Accidents by year

Recorded NTSB general-aviation accidents per calendar year, derived directly from the NTSB accident database. Each bar shows the accidents that occurred in that year. Methodology →

Investigations take 12–36 months to finalise, so the trailing years come in incomplete. Recent years are adjusted upward for that lag. Observed counts show as solid bars, the lag-adjusted estimate shows hatched.

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.
