Buyer's handbook
What an NTSB record actually means for a used aircraft
You searched a tail number, and a National Transportation Safety Board record came back. Before you walk away — or, worse, before you shrug it off — understand what that record is, what it is not, and the one mistake that makes buyers read the wrong aircraft's history entirely. We track 13,616 NTSB records going back to 2008; this is how an experienced buyer reads one.
What the NTSB records — and what it doesn't
The NTSB investigates U.S. civil aviation accidents and serious incidents, and publishes a factual record of each: what happened, the phase of flight, the aircraft, injuries, and — eventually — a probable cause. It is the closest thing general aviation has to a public safety ledger. But it has hard edges you must keep in mind:
- It records events, not repairs. A record tells you an aircraft was damaged; it does not tell you how — or how well — it was put back together. That story lives in the logbooks.
- Minor damage often never appears. A repaired hangar rash or a hard landing handled without an investigation leaves no NTSB trace. Absence of a record is encouraging, never proof.
- The cause can lag by months or years. A recent event may still read "preliminary." Judge it on the factual narrative, not on a probable cause that hasn't been published yet.
A prior record is not automatically a dealbreaker
This is the part buyers get wrong in both directions. A properly repaired incident two owners ago can be a non-issue; a "minor" event with sloppy paperwork can be a money pit. What separates the two is not the severity in the headline — it is three questions:
- What actually happened? Read the factual narrative, not just the injury or damage flag. A gear-up landing on a flat runway is a different animal from an in-flight structural event.
- How was it repaired? Major repairs require specific approvals and sign-offs. The repair should be documented, by a named shop, with the approvals attached.
- Does the logbook match the record? The event, the repair, and the return to service should line up. A damage record with no corresponding logbook entry is the single loudest alarm on this page.
The serial-number trap
Here is the mistake that quietly ruins do-it-yourself history checks. U.S. registrations get reused: an N-number that belonged to one airframe can later be assigned to another. Search the NTSB by N-number alone and you can pull up an accident that belongs to a different aircraft — or miss one that happened while your aircraft wore a different registration.
The fix is to reconcile through the serial number, not the tail number. The serial is the airframe's permanent identity; the registration is just its current license plate. Every TailGuard report does this reconciliation automatically, and flags the records it had to set aside because the serial shows they belong to a previous holder of the same N-number. It is the most common error we see in home-made record checks, and it runs in both directions.
Where to search yourself: data.ntsb.gov CAROL query, free — but do the serial reconciliation by hand, or let the report do it.
Reading the type, not just the tail
Fleet-level NTSB counts describe the type: they reflect how a model is flown as much as the machine itself. A trainer or a busy charter type accumulates events that a privately hangared cruiser never would — that is exposure, not a defect. Our model buyer's guides compute a per-type accident profile from these records and are explicit that the denominator is the current registered fleet, so the ratio understates lifetime history. Use the type profile to calibrate expectations; use the specific airframe's record to make the decision.
What an NTSB record can't tell you
Even a clean NTSB history is not a clean bill of health. The record says nothing about corrosion, undocumented damage, how the aircraft was stored, whether the engine was flown regularly, or the quality of the maintenance between events. That is why the sequence always ends the same way: the record tells your mechanic where to look; a physical pre-purchase inspection by a licensed A&P/IA you chose is what tells you whether to buy.
Check the serial-verified record on one aircraft
A TailGuard report reconciles the NTSB record by serial number for any U.S.-registered airplane or helicopter — so you read your aircraft's history, not a reused registration's — alongside its Service Difficulty Reports, matched airworthiness directives, ownership timeline and a public record coverage.
