Events are NTSB accidents and incidents matched to Cessna 170B airframes by serial number or N-number; counts are approximate, because older events can't always be matched. The yearly rate divides NTSB events from 2016 to 2025 by the number of registered Cessna 170B aircraft in each of those years. Not adjusted for hours flown: training aircraft fly far more than most.
