Aircraft Registration

Frequently Asked Questions

Aircraft Registration Renewal

How do I search aircraft records?

The Aircraft Registration Inquiry contains aircraft registration information. You can also order individual aircraft records by mail, fax, or request copies of aircraft records online.

Will I receive a registration certificate due to the new 3-7 year renewal?

The Registry started automatically reissuing certificates, for aircraft in valid status on January 23, 2023. All aircraft in valid status with expiration date January 31, 2023 – December 31, 2023 are extended an extra 4 years. We intend to reissue registration certificates affected by this Rule, no later than November 30, 2023. The certificate will be mailed to the address in our records.

Do I need a letter of extension?

The Registry will no longer issue letters of extension, effective January 23, 2023. The FAA revised 14 CFR 47.31(c)(1) removing the time limit within which the FAA must either issue a letter extending the temporary authority to continue to operate or deny the application. The Aircraft Registration Application (“Pink Copy”) is valid until the applicant receives the aircraft registration certificate, application is denied by the FAA, or 12 months have elapsed during which the registration is pending on the aircraft.

What aircraft are eligible for registration in the United States?

Eligibility is defined in Chapter 14 Code of Federal Regulations Part 47. You can learn more about aircraft registration on our Register an Aircraft page.

What should I consider when buying a surplus military aircraft?

Certain surplus military aircraft are not eligible for FAA airworthiness certification in the standard, restricted, or limited classifications. Since you can't fly civil aircraft unless it's certificated as airworthy, you should discuss this with an FAA Aviation Safety Inspector (ASI) at your local Flight Standards District Office (FSDO). This person can advise you on airworthiness certification procedures. An additional source for advice on amateur-built and surplus military aircraft is the Experimental Aircraft Association (EAA), located in Oshkosh, WI. You can reach them at (414) 426-4800.

Yes! You can subscribe to ADs and SAIBs at the FAA Regulatory & Guidance Library. Current and historical ADs are also available through RGL.

How do I replace my lost or worn out Certificate of Airworthiness?

How do I report my stolen aircraft?

Stolen aircraft should be reported to your local law enforcement agency. Ask that they report the theft to the National Crime Information Center, as this will initiate notifications to the appropriate government offices. If enough time has passed that the return of the aircraft is no longer expected, the owner should write to the Aircraft Registration Branch requesting that the registration for this aircraft be canceled. The request should fully describe the aircraft, indicate the reason for cancellation, be signed in ink by the owner and show a title for the signer if appropriate.

Where do N-numbers come from?

The U.S. received the "N" as its nationality designator under the International Air Navigation Convention, held in 1919. The Convention prescribed an aircraft-marking scheme of a single letter indicating nationality followed by a hyphen and four identity letters (for example, G-REMS). The five letters together were to be the aircraft's radio call sign.
