Effective January 23, 2023, if your registration certificate expires after this date, the registration certificate will automatically be extended an additional 4 years. 

A new certificate with the new expiration date will be sent to you.

Aircraft with an expired registration, airworthiness certification is considered ineffective. Without registration, the aircraft is not authorized for flight. Once registration is restored, the airworthiness certificate not having been surrendered, revoked or terminated would become effective again provided the aircraft is otherwise compliant with maintenance, inspections, and any other requirements for an effective airworthiness. If you have further questions please contact an airworthiness inspector through your nearest Flight Standards District Office.

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. To report an address change click here.

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.

Can new Airworthiness Directives and Special Airworthiness Information Bulletins about my aircraft and its engines be sent to me by e-mail?

Yes! You can subscribe to ADs and SAIBs at the FAA Document Regulatory System (DRS). Current and historical ADs are also available through DRS.

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

Your local Flight Standards District Office (FSDO) processes replacement airworthiness certificates.

How do I find the nearest FAA Flight Standards District Office (FSDO)?

You can use our FSDO locator to find your local FSDO office. FSDOs are also listed in the U.S. government pages of your local telephone book under Federal Aviation Administration.

How can I find out if the Aircraft Registration Branch received my registration documents?

You can check to see if the Aircraft Registration Branch received your documents using the Document Index search located on the Aircraft Inquiry page accessed by selecting the Search Aircraft Registration Information link from the main menu or the "Top Tasks" feature.

How long does it take to process aircraft registration documents?

In compliance with statutory requirements, documents are worked in the order we receive them. You can find the current processing date here.

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. Read more about N-number history.
