From the NTSB's aviation accident database, refreshed monthly; accidents only, homebuilts left out. Counts, not rates: nobody publishes how many hours each model flies, and a training fleet flies far more than a private one. Look up any case by its number in the NTSB's CAROL.

Before you buy one

Run its N-number through the AD check: every AD that names its airframe and engine, as a checklist to take to the logbooks.
For each repeat-action AD, find the last compliance in the logbooks and when the next one is due.
Compare the engine's time since overhaul with its maker's published overhaul time, and look for the reason behind any long gap in flying.
Check the registration, the airworthiness certificate and the date of the last annual inspection.
Work out the sales or use tax your state will charge with the aircraft tax calculator.
