FAA singleton-type analysis
The only one of its type on the valid US register
Every exact, normalised manufacturer/model combination represented by a single valid, non-expired US registration.
Important: Many results are amateur-built aircraft because FAA manufacturer values often identify the individual builder. “Only one” applies to the exact normalised FAA manufacturer/model combination—not necessarily the broader aircraft design.

Methodology
How the list was made
- Restricted to valid, non-expired registrations in the 50 states with plausible manufacture years.
- Normalised whitespace and case in the FAA manufacturer and model fields, then retained combinations appearing exactly once.
- Included every qualifying singleton, including custom and amateur-built aircraft, so the download is complete under the stated definition.
Editorial use
What still needs checking
For a production-aircraft story, review and curate the results rather than assuming every row is a globally unique surviving design.
