Safety Analysis

Composition of NTSB accident records for this model in general-aviation operations (FAR Part 91 and 137), based on NTSB data as of May 1, 2026. It's a breakdown of recorded accidents rather than a safety rating, and types with significant non-GA operation (such as Part 135) may be under-represented.

Identity Confirmed

Accidents are identity-confirmed against FAA registration records (two independent sources).

Comparison

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 →
