1. Service Description

Tailfinder is a free search tool that helps users find available FAA aircraft registration numbers (N-numbers). The service aggregates publicly available data from the Federal Aviation Administration (FAA) and presents it in a searchable format.

2. No Affiliation with FAA

Tailfinder is not affiliated with, endorsed by, or connected to the Federal Aviation Administration (FAA). This is an independent service that uses publicly available FAA data.

Important: All N-number registrations must be completed through official FAA channels. Tailfinder provides informational data only and cannot register or reserve N-numbers on your behalf.

3. Data Accuracy and Disclaimer

While we strive to provide accurate and up-to-date information:

  • Data is synced daily but may not reflect real-time changes
  • Availability information is provided "as-is" without warranties
  • We are not responsible for errors or omissions in the data
  • Always verify availability directly with the FAA before reserving an N-number

You agree to use Tailfinder only for lawful purposes. You must not:

  • Attempt to overwhelm or disrupt the service (e.g., denial-of-service attacks)
  • Use automated tools to scrape or download excessive amounts of data
  • Reverse engineer or attempt to extract the source code
  • Violate any applicable laws or regulations
  • Use the service to harass, spam, or harm others

5. Intellectual Property

Tailfinder is open-source software. The source code is available on GitHub and licensed under the MIT License. However:

  • The Tailfinder name and branding are owned by the project maintainers
  • FAA data is in the public domain and owned by the U.S. government
  • Third-party libraries and components are subject to their respective licenses

6. Service Availability

We strive to keep Tailfinder available and functional, but we do not guarantee:

  • Uninterrupted or error-free service
  • That defects will be corrected
  • That the service will be available at any particular time
  • That the service will continue to be offered in the future

We reserve the right to modify, suspend, or discontinue the service at any time without notice.

7. Limitation of Liability

TO THE MAXIMUM EXTENT PERMITTED BY LAW: Tailfinder and its operators are not liable for any indirect, incidental, special, consequential, or punitive damages arising from your use of or inability to use the service. This includes, but is not limited to, damages for loss of profits, data, or other intangible losses, even if we have been advised of the possibility of such damages.

You use Tailfinder at your own risk. The service is provided "as-is" without warranties of any kind, express or implied.

9. Third-Party Links

Tailfinder contains links to third-party websites (such as FAA.gov). We are not responsible for the content, accuracy, or practices of these external sites. Use them at your own discretion.

10. Changes to These Terms

We may update these Terms of Service from time to time. The "Last updated" date at the top indicates when changes were last made. Your continued use of Tailfinder after changes constitutes acceptance of the updated terms.
