Scan the label. See whether the record matches what was signed.
Every signed entry can carry a printed QR label. Scanning it opens a public page with the entry, the signer, their certificate and the signing time, checked against the stored hash. No account, no login, no phone tag.

How to read a label, and what the scan shows.
Labels are pasted into the paper logbook or kept with the aircraft's records. Each one points at one signed entry.
Read the label
It names the entry number, the tail number and the signer, so you know which record you're about to check.
Scan the code
Any phone camera will do. It opens a public verification page; there is nothing to sign up for.
Compare
The page shows the entry as it was signed, with the signer, their certificate snapshot, the signing time and the tail number. Check that against the airplane and the paper in front of you.
Read the status line
“Signature verifies” means the record matches what was signed. If it says anything else, stop and ask the owner.

What “verifies” means.
Two checks pass, and both are about the record itself:
- The entry matches its stored hash. The text you're reading is the text that was sealed; a change since signing would be detectable.
- The signature commits to that exact version. The signer signed this text, not an earlier draft and not a later edit.
If an entry was corrected, the correction is a new version linked to the original, signed by the same signer. The original stays in the record to compare against.
Signing follows the electronic-signature practices in AC 120-78B.What it does not claim
- It is not an airworthiness determination. A verified record says nothing about whether the aircraft is airworthy today.
- It doesn't say the work was done well. It confirms who signed what, and that the record hasn't changed since.
- It doesn't replace the inspector's judgement, the buyer's mechanic, or a look at the airplane itself.
Acceptability of the record rests with the operator and the mechanic, as it does on paper.
The buyer's mechanic opens the book first.
Every prebuy starts with the logbooks. Gaps, missing signatures and unreadable entries come off the price, or end the deal.
A history kept in Aero Logworks reads clean because it was kept clean: every entry signed with a name and certificate number, every correction linked to its original, every signed entry checkable against its hash. The buyer's mechanic can check any labelled entry on the spot, tonight, three states away.
A shared prebuy records room coming will let a seller open the whole history to a buyer for the length of the deal.
