Is there an open dataset of aircraft parts?

Each part has a unique number. Several services provide search across resellers. These searches return little details on the part itself, only reseller contacts.

FAA maintains several datasets, one of which is aircraft vehicle registrations:

No parts data. Though someone must certify all parts and assign numbers.

Who maintains this data or is supposed to have it?

  • What makes you think parts have a unique number? Usually its only unique to a manufacturer, so you need the manufacturer ident as well. Then the manufacturer may keep it proprietary.... For US military (some NATO) stuff, FEDLOG (dla.mil/HQ/InformationOperations/Offers/Products/…) is the authority, but its arguable whether its open data.

Parts Manufacturer Approvals

FAA actually publishes parts approvals, but Google doesn't show it in top results:

This database contains the FAA Parts Manufacturer Approvals and may be viewed by make, PMA Holder, and part number.

Aircraft Replacement Parts Guide

A commercial database that groups standard parts together:

It helps in matching similar parts with different approval numbers.


Also another commercial PN database (this one is really huge, I think they say that they have more than 50 millions PNs): https://partnumber.bid
