Registering and Operating a Jet Internationally: FAA, EASA, Offshore Registries and Cabotage

An aircraft has a nationality, and that nationality determines who may own it, who may fly it, how it is maintained, where it may carry paying passengers and how it is taxed. Choosing a registry is therefore one of the most consequential decisions in an acquisition, and one that international owners in particular get wrong by defaulting to whichever flag the seller used. This guide sets out the main options and the rules that follow from each.

The United States: N-registration

The FAA registry is the world's largest, with roughly two-thirds of the global business jet fleet. Its attractions are liquidity (an N-registered aircraft sells into the deepest market), a mature legal framework for financing under the Cape Town Convention, and a permissive private-operation regime.

Ownership. Registration requires a US citizen, a US corporation meeting citizenship tests, or, for foreign owners, a non-citizen trust in which a US trustee holds legal title. Owner trusts are common and well understood by lenders, but they attract periodic FAA scrutiny and add a layer of cost and documentation.

Operating rules. Part 91 governs private, non-commercial operations. It is flexible on crew duty time, maintenance intervals and airports, and it allows a company to fly its own executives and, within limits, to be reimbursed by affiliated entities. Part 135 governs commercial charter. An aircraft on a Part 135 certificate must meet stricter maintenance, crew training and operational standards, and the certificate holder, not the owner, has operational control. Most owner aircraft that charter are placed on a management company's Part 135 certificate and flown under Part 91 when the owner is aboard.

The cabotage trap. A foreign-registered aircraft may fly into and out of the United States freely for private use, but it may not carry passengers for compensation between two US points. Conversely, an N-registered aircraft based abroad faces the same restriction in the country where it lives.

Europe: EASA and national registries

Within the European Union, aircraft are registered nationally (Germany D-, France F-, Austria OE-, Malta 9H- and so on) but operate under common EASA rules.

• Part-NCC applies to non-commercial operations of complex motor-powered aircraft, which means every business jet. It requires a declared operator, a management system, an operations manual and compliance monitoring: more structure than Part 91, less than an AOC.
• Part-CAT with an Air Operator Certificate governs commercial charter, the counterpart to Part 135.
• Part-NCO covers simpler aircraft and is not relevant to jets.

Registration requires a qualifying EU ownership or operating entity, which usually means an EU company. Malta and Austria have built specialist business-aviation registries with efficient administration and attractive VAT and leasing arrangements, and they have taken a growing share of European registrations since Brexit removed the UK's G-register from the EASA system. The UK now operates its own post-Brexit rules that mirror EASA closely.

Third-country operators. Non-EU aircraft flying charter into Europe need a TCO authorisation from EASA in addition to their home approvals; private flights do not.

The offshore registries

Roughly a fifth of the world's large business jets fly under a flag other than their owner's home country. The offshore registries serve three purposes: they accept owners of any nationality, they offer a neutral, English-law-friendly jurisdiction for financing, and they carry no tax of their own on the aircraft. Each has a distinct profile.

An offshore registration does not exempt an aircraft from the operating rules of the country where it is based. A Cayman-registered Global based in Hong Kong is still subject to Hong Kong's CAD rules on where it may park and who may fly it; a San Marino-registered Falcon in Riyadh must comply with GACA requirements. What the registry gives you is a stable legal home for the asset and a straightforward path to financing.

Asia and the Middle East

China requires B-registration for aircraft owned by domestic entities and imposes import duty and VAT; most privately used aircraft in Greater China are therefore either registered in Hong Kong (B-K and B-L prefixes) or offshore and operated by a Hong Kong or Macau-based management company. Singapore (9V-) and Japan (JA-) have small but growing business aviation registries. In the Gulf, the UAE (A6-) and Saudi Arabia (HZ-) have modernised their regulations, and Saudi Arabia's GACA has since 2024 opened domestic routes to foreign-registered charter operators in a limited form, an exception to the cabotage norm.

Cabotage: the rule that trips up everyone

Cabotage restrictions prohibit a foreign-registered aircraft from carrying passengers or cargo for hire between two points inside a country. Private, non-revenue flights are generally permitted; charter is not. The definition of hire can be broad: some authorities treat cost-sharing between affiliated companies as compensation. Common failure modes:

• A US-registered jet on a European charter certificate picking up a paying passenger in Paris and dropping them in Nice.
• A Cayman-registered aircraft carrying an owner's business guests between two Chinese cities under an arrangement that looks like a charter.
• An EU-registered aircraft doing repeated intra-Brazil flights with fee-paying passengers.

Penalties range from fines to aircraft seizure. The standard advice is simple: if the aircraft will regularly carry paying passengers within a country, register and certificate it there.

Choosing: a practical framework

• If you are a US person or company flying mainly in the Americas, N-registration under Part 91, with a Part 135 arrangement if you charter, is the default.
• If you are an EU person or company, register in Malta, Austria or your home state under Part-NCC or with an AOC.
• If you are based outside the US and EU and fly privately, Cayman or Isle of Man will suit most owners; choose Cayman or San Marino if any commercial use is planned.
• If you fly a bizliner or want a registry that lenders in every region accept, Cayman or Bermuda.
• If you charter inside one country regularly, register there, whatever the paperwork.

Tax structuring, importation and VAT deserve their own discussion. But the registry is where every international owner should begin, because it decides what the aircraft is allowed to do before anyone works out what it costs.
