About this dataset
Public N-number registry with owner, manufacturer, model and registration status. Every row of the full MASTER.txt file — all N-numbers, with the FAA status code stored verbatim, including revoked, canceled and expired registrations — plus ACFTREF.txt (aircraft reference) and ENGINE.txt (engine reference). We do not ingest the other members of the same ZIP: DEREG.txt, RESERVED.txt, DEALER.txt and DOCINDEX.txt. Powers tail-number lookup and the Aircraft Reference linkage.

A region on this list means we fetch it. It is not a promise of station density: a listed region can still have sparse or no reporting sites near a given airport.
