Check the official record

This page mirrors the FAA's public registry file dated Oct 30, 2026. The FAA's own N-number inquiry is the official record, with the full owner address and documents.

Where is it now?

The registry doesn't show where an aircraft is flying. Flight trackers do, by tail number or Mode S code A4482C: FlightAware or ADS-B Exchange. Some owners block tracking through the FAA's privacy programs.

Something wrong?

Owners update their registration with the FAA Aircraft Registry; changes appear here the day after the FAA publishes them. Email admin@whoownsthisplane.com about how this site shows a record.
