View earlier registration history

TailWiki has tracked this tail since Aug 2026. The FAA registry is a snapshot, not a history — earlier owners aren't in the public record. TailWiki reconstructs ownership changes by watching daily FAA updates going forward, so this section fills in the longer TailWiki runs.

About this record

This N-number isn't actively registered, so it can't be claimed. If the FAA reissues it to a different aircraft, that new registration gets its own page.
