US Fleet Size & Accident Rates
The most widely flown aircraft in each category. Fleet counts come from the current FAA registry; accident figures are NTSB investigations from the last 10 years, matched by make, model family and engine type, shown as a rate per 1,000 registered aircraft. Rates are per airframe — models that fly more hours (trainers, charter fleets) naturally accumulate more events per airframe. Updated 2026-08-17.
