Guernsey aircraft registration process step-by-step

Registering an aircraft on the Guernsey register (prefix 2-) follows a fixed sequence: confirm eligibility, decide how the aircraft will operate, assemble documents before applying, complete registration, then keep meeting ongoing obligations for as long as the aircraft stays registered. Expect the paperwork stage to take longer than the registry's own processing.

1. Confirm eligibilityLink to this section#

Start by checking that the aircraft and the intended owner qualify. Registries commonly restrict the maximum take-off mass (MTOM) or age of aircraft they will accept, and who may hold legal title. Guernsey's position on this: Aircraft must be type certificated and 5,700 kg maximum take-off mass or above; Channel Islands residents may register any type-certificated aircraft, non-residents a lighter turbine aircraft only on conditions, and amateur-built and vintage aircraft are refused.?Office of the Aircraft Registrar, Bailiwick of Guernsey, Guernsey Advisory Circular GAC REG-1, 'Aircraft Registration: Eligibility and Admission Criteria', Fourth Issue, April 2026cidca.aero · GAC REG-1, para 6.2×Retrieved 2026-08-12Open source ↗!Informational only, not legal, tax or financial advice. Contact a qualified professional for current information.

The regulatory regime the aircraft will operate under is also settled at this stage, since it determines what airworthiness evidence is needed and what oversight follows. Guernsey's regulatory status: Guernsey runs its own ICAO-based rules; type certificates can be chosen from EASA, FAA, UK CAA, TCCA or ANAC.?2-REG (Guernsey Aircraft Registry), Follow TC conceptwww.2-reg.com×Retrieved 2026-08-12Open source ↗!Informational only, not legal, tax or financial advice.

2. Choose the operating categoryLink to this section#

Decide up front whether the aircraft will fly purely privately or under commercial air operations. The paperwork and downstream approvals differ, and converting a private registration to commercial later is far more work than deciding correctly at the outset. Guernsey's position on this split: Private complex operations need a Private Operator Certificate, valid three years; commercial air transport needs an AOC.?2-REG (Guernsey Aircraft Registry), Private Operator Certificatewww.2-reg.com×Retrieved 2026-08-12Open source ↗!Informational only, not legal, tax or financial advice.

3. Pre-application preparationLink to this section#

Assemble title evidence, deregistration confirmation from any prior register, and, if the aircraft is financed, the documentation a lender will expect. Where the Cape Town Convention applies, this commonly includes an Irrevocable De-Registration and Export Request Authorisation (IDERA), signed in advance so a named creditor can deregister and export the aircraft without the owner's further cooperation if the debt goes unpaid. It gives financiers confidence in the international enforceability of their security, which in turn affects the terms on offer.

4. Article 83bis, if the aircraft is registered elsewhereLink to this section#

Article 83bis of the Chicago Convention lets the state of registry and the state of operation agree to transfer specified regulatory responsibilities (airworthiness, licensing, operational oversight) between them without changing the aircraft's nationality mark. This matters when an aircraft keeps its existing registration but will be operated elsewhere, or the reverse. Guernsey's position on 83bis arrangements: Aircraft under an Article 83 bis agreement must carry a certified true copy of the agreement summary.?Guernsey Aviation Requirements Parts 91, 121 & 135, 'General Operating Instructions & Commercial Air Transport Operations', Guernsey ODCA issue 14cidca.aero · GAR 91.47×Retrieved 2026-08-12Open source ↗!Informational only, not legal, tax or financial advice.

5. Application and feesLink to this section#

The formal application, supported by the documents from the steps above, is filed with the registry. Its current fee position: Registering an aircraft costs £300, de-registration £250 and a change of ownership £200, but 2-REG says its fees are flexible to each case.?2-REG (Guernsey Aircraft Registry), Fee schedule v10.1, 13 August 2024www.2-reg.com · Fee schedule v10.1, items 1.1-1.3×Retrieved 2026-08-12Effective 2024-08-13Open source ↗!Informational only, not legal, tax or financial advice.

6. Mortgage or charge registration, if financedLink to this section#

Where financing is in place, the lender's mortgage or charge is registered as its own step, giving that security public priority and enforceability. Guernsey's mortgage and charge position: Registered charges rank by date of registration and outrank unregistered ones; registering one costs £290 and on default the chargee may repossess and sell.?Aviation Registry (Guernsey) Law, 2013 (Order in Council No. XIII of 2013), section 35 'Priority of charges and debts', published by the States of Guernsey on Guernsey Legal Resourceswww.guernseylegalresources.gg · s. 35(1)–(3), Aviation Registry (Guernsey) Law, 2013×Retrieved 2026-09-08Effective 2024-08-13Open source ↗!Informational only, not legal, tax or financial advice.

7. Certificate of registrationLink to this section#

Once the registry is satisfied, it issues the certificate of registration and the aircraft carries its Guernsey marks. The aircraft is legally on the register from this point, and the obligations of staying registered run from here.

8. Post-registration obligationsLink to this section#

Registration brings obligations that continue. Continuing airworthiness must be actively managed for as long as the aircraft stays registered, typically through a Continuing Airworthiness Management Organisation (CAMO) that plans and tracks maintenance against the aircraft's approved basis. Guernsey's CAMO requirement: Aircraft of 2,700 kg MTOM or above need a Technical Co-ordinator or a validated CAMO.?2-REG (Guernsey Aircraft Registry), Continuing airworthinesswww.2-reg.com×Retrieved 2026-08-12Effective 2024-08-13Open source ↗!Informational only, not legal, tax or financial advice.

How long does registering an aircraft take?Link to this section#

The registry's published turnaround runs from the point its file is complete, not from the day an owner decides to move. Assembling title, airworthiness and financing papers is the part an owner controls, and on most applications it is the longer half of the calendar by a wide margin.

Do you have to be in Guernsey to register an aircraft?Link to this section#

Not usually. Registration is normally filed by a local registration agent or law firm acting for the owner, so personal presence is rarely required. What the register does ask is who may hold title to an aircraft on it, which is the question a local structure is generally built to answer.

Does the register set weight or age limits?Link to this section#

Every register publishes its own answer and some set no limit at all. Where a limit does apply and a specific aircraft falls outside it, the choice is made for the owner before any fee comparison starts, so check this first.

Is an IDERA needed for an aircraft owned outright?Link to this section#

Usually not. An irrevocable deregistration and export request authorization exists to protect a creditor's security interest, so it belongs to financed aircraft. An owner buying without a lender should still read the register's own position, because the Cape Town framework is applied differently from state to state.

What obligations continue after the certificate issues?Link to this section#

Continuing airworthiness management is the main one, and it runs for as long as the aircraft stays on the register. Alongside it sit whatever license validation the register requires of the flight crew and the framework it applies to the aircraft's certification.

Who runs this process for an owner?Link to this section#

Registration agents and aviation lawyers file these applications every week and hold the title chain together. Read the cost guide for what each step costs, check timing with the registration timeline checker and the papers with the documents checklist generator, compare on the Guernsey aircraft pillar, then ask a specialist.

Is this legal or tax advice?Link to this section#

No. The steps above are informational only, and every aircraft's path depends on its history, its financing and how it will be operated. Compare Guernsey against the Isle of Man before committing to either.
