Airworthiness Directives
25 current ADs name the 45 airframe, 6 with a repeat action; 2 more were superseded. Its engines carry 46 more.
The ones that come back
ADs with a repeat action: an inspection or replacement at an interval, for as long as the AD applies. These are the airworthiness costs an owner keeps paying.

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 (6 on the airframe), 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.
