For lessors, parts buyers, repair stations and aviation insurers

Don't pay for a part whose history might be forged.

An engine part can sell for hundreds of thousands of dollars, and its value depends entirely on its paperwork. Parts with forged release certificates have reached airline engines, and grounding aircraft to find them costs far more than the parts themselves.

The manufacturer signs a fingerprint of the original release certificate when the part is made, and every shop signs what it received. A forged copy can look perfect, but it can't match the fingerprint.

What it costs you today

Before a sale or a lease return, buyers and lessors pay specialists to reconstruct a part's history back to birth, and still rely on documents that can be copied or altered. When forged paperwork is found after installation, operators ground aircraft, pull parts and absorb the cost.

What changes

Check a part before you pay

Each handoff and repair is signed by the organization that did it, with a fingerprint of the certificate, so a gap or an altered document shows up before money changes hands.

Faster lease returns

A part's full chain is one file anyone can verify, instead of weeks of records review.

Contain a bad-part event

If one supplier's paperwork turns out to be forged, every part it touched can be found at once.

The answer

Free in your browser: the manufacturer registers the part, every shop signs what it received and what it did, and a buyer checks the certificate it was sent. A paid report adds a signed rating for lenders and insurers.

How it works

Each party signs a small record at the moment it takes responsibility. The records chain together, so a missing, edited or forged one is caught.

RecordSigned bySays
aviation.part/1the manufacturerpart number, serial, and a fingerprint of the original release certificate
aviation.handoff/1the receiving organizationreceived this part from that organization, with this certificate fingerprint
aviation.work/1the repair stationwork performed, a fingerprint of the new certificate, and the record it follows

All records use canonical JSON, a SHA-256 fingerprint and an Ed25519 signature, the same primitives proven in our space custody work.

A real run

Fuel pump FP-4420-01, serial FPX10417: 6 signed records back to birth
  2019-03-04  born       pump maker
  2019-03-16  handoff    parts distributor
  2019-04-13  handoff    airline
  2024-05-16  handoff    repair station
  2024-06-20  overhaul   repair station, new release certificate
  2024-07-05  handoff    parts broker
Verified against the organization key registry: PASS

The buyer checks the certificate the broker sent:
  overhaul certificate, as issued             genuine and current
  original certificate from birth             genuine but superseded
  overhaul certificate with the date edited   not genuine
  certificate copied from another serial      not genuine

Tampering:
  overhaul added by an unregistered shop      caught
  broker signs an overhaul itself             caught
  repair record rewritten as an inspection    caught
  the airline's years of service removed      caught
  part received with a different certificate  caught
  supplier signs after its key was revoked    caught

Containment: 72 of 500 parts passed through the bad supplier, found in one query

Certificates are never stored, only fingerprinted, so an edited or re-used document fails the check before money changes hands.
