Why registration is essential
No aircraft can legally fly in Europe without a valid registration: it is what links the aircraft to a civil aviation authority (DGAC in France, LBA in Germany, CAA in the United Kingdom…), allows the issuance of the certificate of airworthiness and is a condition for insurance. When buying a used aircraft, transferring the registration to the new owner's name is a mandatory step, distinct from simply signing the bill of sale.
Until this transfer is finalized, the previous owner remains legally responsible for the aircraft in the eyes of the authorities — a point often overlooked that can create complications in the event of an incident.
Choosing your country of registration
Most buyers register the aircraft in their country of residence, but this is not a requirement within the European Union: an aircraft based in France can be registered in Germany or Ireland, for example for tax reasons or administrative convenience with a foreign register already familiar to the buyer.
- National registration (e.g. F- in France, D- in Germany, G- in the United Kingdom) — the simplest route if you reside and base the aircraft in the same country.
- Well-known foreign registers — Ireland (EI-) and Malta (9H-) are commonly used for VAT tax reasons or flexibility for professional operators.
- Case of microlights — microlight registration follows a simplified declarative regime, specific to each country, independent of the standard general aviation regime.
The application file to prepare
The required application file varies slightly depending on the national authority, but a common core is required everywhere in Europe.
- Bill of sale — dated, signed by both parties, stating the serial number and the previous registration.
- Proof of deregistration from the previous register — mandatory in case of a change of country of registration.
- Valid certificate of airworthiness — or renewal file if expired.
- Proof of ownership and identity — identity document or company registration extract for a company.
- Liability insurance certificate — required before first use under the new registration.
- Requested nationality and registration mark — some registers allow reserving a customized combination of letters for an additional fee.
Timelines and costs
Generally allow 2 to 8 weeks depending on the country and the completeness of the file — incomplete applications or those with an international history take the longest to process. Administrative fees remain modest (typically a few hundred euros depending on the register), but are often added to certificate of airworthiness transfer fees and, for an aircraft coming from a non-EU country, customs clearance and EASA compliance costs.
| Step | Indicative timeline |
|---|---|
| Submission of complete file | Immediate |
| Administrative review | 2 to 6 weeks |
| Issuance of the new registration | 1 to 2 additional weeks |
| Case of a foreign register (e.g. non-EU import) | 2 to 4 months |
After registration: what changes
Once the new registration is issued, update your insurance certificate, inform your home airfield and have the registration marks repainted on the aircraft within the timeframe set by local regulations (generally 30 days). Keep all documents carefully: they will be requested again for a future resale.
