How to Check an Airplane's History Before You Buy

Every airplane accumulates a paper trail — federal, mechanical, and its own — before it ever gets listed for sale. Reading that trail correctly is the difference between an educated purchase and finding out about a problem after you already own it.

Start with the FAA registry

The FAA aircraft registry tells you who currently holds title, the airframe's serial number, and whether the registration is current. It also records liens against the aircraft, which matter because a lien follows the airplane, not the seller — you do not want to buy someone else's debt. What the registry does not tell you is condition. It says nothing about hours, damage, or maintenance. Treat it as a starting point for matching everything else, not a verdict on the airplane.

Airworthiness directives: applicability, not compliance

Airworthiness directives (ADs) are FAA mandates tied to a specific make, model, and sometimes a serial-number range or installed equipment. Two different questions get confused constantly:

• Applicability — does this AD apply to this airframe at all, based on its model, serial number, and equipment?
• Compliance — has the applicable AD actually been done, and is the paperwork in the logs to prove it?

We report applicability — which ADs are relevant to a given tail — because that is derivable from public FAA data about the airframe itself. Compliance can only be confirmed by a mechanic physically reviewing the logbooks, which is prebuy territory, not desk research. Never assume a directive was complied with just because it is old or common; the logbook entry is the only proof.

Damage history is a fact, not a verdict

A prior gear-up landing, a prop strike, or a repaired hail event shows up in NTSB records or in the logs as a major-repair entry. None of that automatically makes the airplane a bad buy. A properly documented repair, signed off by a mechanic with the right authority and matching parts records, can leave an airframe every bit as airworthy as one that never had an incident. What matters is whether the repair is documented — an accident with no corresponding repair entry in the logs is the real problem, not the accident itself.

Logbook gaps deserve more attention than most single findings

A missing month of entries is usually nothing. A missing year, or a logbook that starts mid-life with no reference to the aircraft's earlier history, is a bigger question than almost any individual squawk, because it removes your ability to verify everything else — ADs, repairs, even total time. A gap does not prove something was hidden, but it removes your ability to check, and that uncertainty should be priced into your offer or resolved before you close.

Match on serial number, not just the N-number

N-numbers are reassigned. When an owner cancels a registration, the FAA can eventually reissue that same N-number to a completely different airplane. If you pull records — accident history, AD applicability, even online marketplace history — using only the tail number, you risk pulling another airplane's history entirely. Always cross-check the airframe serial number recorded in the logbooks against the serial number on the FAA registry entry before you trust anything you find.
