FAA Registration: Registering an Aircraft in the United States

Who is eligible to register an aircraft with the FAA?

Only US citizens, resident aliens, US-based corporations meeting citizenship tests, or qualifying non-citizen owner trusts can hold an FAA registration. The statute under 49 USC 44102 is strict: a US corporation qualifies only if the president and at least two-thirds of the board and managing officers are US citizens, and 75% of voting interest is held by citizens. Partnerships must consist entirely of US citizens — no LLCs treated as partnerships with foreign members.

This is where most foreign buyers hit a wall. The workaround is the non-citizen owner trust, where a US trustee (Bank of Utah, Wells Fargo, TVPX, Aircraft Guaranty Corporation are the dominant players) holds title and the foreign beneficiary holds the economic interest. The FAA tightened trust rules in 2013 and has been scrutinizing them ever since, but properly structured trusts remain the standard path for European and Asian buyers operating N-registered aircraft.

What documents does the FAA actually require?

The core filing is AC Form 8050-1 (Aircraft Registration Application) plus AC Form 8050-2 (Bill of Sale) from the seller, submitted to the FAA Aircraft Registry in Oklahoma City with a $5 fee. That is the entire base filing. Everything else — title opinion, escrow instructions, IRS Form 8050-41 for trust filings, lien releases on AC Form 8050-41 — supports the transaction but is not the registration itself.

In practice, you will also need a clean title search from a firm like Aerospace Reports, Insured Aircraft Title Service, or AIC Title Service, and your closing escrow agent files everything simultaneously at Oklahoma City through the FAA's counter service. Documents physically hand-delivered at the counter post immediately; mailed documents now sit in a queue that has run 6-12 weeks during recent backlogs.

How does the N-number reservation work?

You reserve an N-number through the FAA Civil Aviation Registry online for $10, holding it for one year and renewable annually. N-numbers follow a strict format: one to five characters after the "N," using digits 1-9 and letters except I and O (to avoid confusion with 1 and 0), and never starting with zero. So N1 through N99999 are valid, as are combinations like N123AB.

Custom N-numbers — vanity tails matching initials, tail number-as-call-sign, or sequence numbers across a fleet — are the norm for private buyers. If you are buying a used aircraft and want to keep the existing registration, no reservation is needed; the number transfers with the aircraft unless you affirmatively change it. If you want to change it at closing, file AC Form 8050-64 (Assignment of Special Registration Numbers) with the registration application.

What is the difference between registration and airworthiness?

Registration proves ownership; airworthiness proves the aircraft is legal to fly. These are two separate FAA-issued documents, and confusing them is a rookie mistake. The Certificate of Registration (the pink slip you keep in the aircraft) is issued by the Aircraft Registry. The Standard Airworthiness Certificate is issued under 14 CFR Part 21 and remains valid as long as the aircraft is maintained per Part 91 inspection requirements and the type certificate.

A US-built jet coming from a foreign registry needs both: registration under 49 USC 44103 and a fresh airworthiness certificate issued by a local FSDO (Flight Standards District Office) after a conformity inspection. Budget two to four weeks for the airworthiness piece on an import, plus any corrective maintenance to bring the aircraft into US-spec configuration.

How long does the registration process take?

Counter-service filings at Oklahoma City close same-day with a temporary "fly-wire" authorization good for 90 days, while permanent certificates have been running 4-8 weeks. The fly-wire (technically a temporary authorization under 14 CFR 47.31) is what every closing escrow agent uses to get the buyer flying immediately after funds release. The permanent pink slip arrives by mail later.

If you mail the filing yourself instead of using an escrow agent at the counter, expect significant delays. The Registry's mail-in queue has been one of the most criticized bottlenecks in general aviation, and it is the single biggest reason buyers pay $5,000-$15,000 for professional closing services rather than handling registration themselves.

What changed with the 2024 seven-year renewal rule?

Effective 2024, the FAA extended the registration renewal cycle from three years to seven years, aligning with congressional direction in the 2018 FAA Reauthorization Act. Existing registrations on the old three-year cycle convert at their next renewal. The renewal fee remains $5, and renewal is filed on AC Form 8050-1B.

Letting registration lapse is the single most common avoidable error in private aviation ownership. A lapsed registration means the aircraft is unairworthy for flight under 14 CFR 91.203, voids insurance, and triggers reregistration rather than renewal — a more involved filing. The FAA mails reminder notices, but if you have changed your address without filing AC Form 8050-1 to update the Registry, you will never see them.

What are the most common registration pitfalls in a transaction?

The recurring problems are LLC structure defects, undisclosed liens, address-of-record errors, and improperly executed bills of sale. An LLC owned by a single-member holding company with a foreign parent will fail the citizenship test even if every signatory is American. Title searches catch most liens, but mechanic's liens and tax liens filed locally rather than at Oklahoma City have surfaced after closing more than once.

Address-of-record matters because the FAA sends renewal notices, AD compliance notices, and registration correspondence to the address on file. Owners who register to a hangar address that later changes, or to a management company address after switching managers, routinely miss critical notices. Use a permanent business address and update it within 30 days of any change, as required by 14 CFR 47.45.

Finally, the bill of sale and registration application must be signed by an authorized officer of the LLC or corporation with documented signing authority. Escrow agents catch this, but if you are closing without one, the Registry will kick the filing back and your aircraft sits grounded until the paperwork is corrected.
