Events are NTSB accidents and incidents matched to Learjet 31A 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 Learjet 31A aircraft in each of those years. Not adjusted for hours flown: training aircraft fly far more than most.
