What Documents Are Required When Buying an Aircraft?
The ownership, registration and technical documents to check before buying an aircraft, with examples from the US, Europe and other jurisdictions.

Every country has its own registration rules, so there is no single global checklist. What is universal is that an aircraft purchase involves two separate sets of documents: those that prove who owns the aircraft, and those that prove what condition it is in and that it can legally fly. Both deserve independent review before money moves.
Ownership and transaction documents
Typically, a buyer and their lawyer will want:
Proof of the seller's identity and authority to sign (for companies, board resolutions or a power of attorney).
The signed letter of intent and the definitive aircraft purchase agreement.
Evidence of the chain of title from previous owners.
A bill of sale or equivalent transfer document, in the form required by the registry.
Title and lien search results, and releases of any existing mortgages or liens.
Escrow instructions and, if financed, the loan and security documents.
Identity and source-of-funds information for anti-money-laundering and sanctions checks.
The Cape Town Convention and the International Registry
Many countries have adopted the Cape Town Convention and its Aircraft Protocol. Interests in qualifying aircraft objects are registered in the International Registry, an online, worldwide register. Qualifying objects include airframes certified to carry at least eight people including crew (or more than 2,750 kg of cargo), helicopters certified for at least five people including crew (or more than 450 kg of cargo), jet engines of at least 1,750 lb thrust and turbine or piston engines of at least 550 rated take-off shaft horsepower. Engines are registered separately from airframes, so they must be searched separately. Your lawyer will confirm whether it applies to your aircraft and your countries.
Registration: examples from different jurisdictions
Registration is handled by the national aviation authority of the state of registry. Some examples:
United States: The FAA Aircraft Registry uses AC Form 8050-1 (Aircraft Registration Application) and AC Form 8050-2 (Aircraft Bill of Sale). After filing, the applicant's copy of the application can serve as temporary authority to operate for a limited period, but only within the United States.
Europe: Registration is handled by each national authority (for example, the civil aviation authority of the relevant country), while continuing-airworthiness rules are harmonized under EASA. Many aircraft also need a valid Airworthiness Review Certificate (ARC).
Other regions: Authorities such as the UK CAA, Transport Canada, DGCA India, ANAC Brazil, CASA Australia and the GCAA in the UAE each have their own forms, eligibility rules and timelines. Some impose import approvals or age limits on used aircraft.
Forms and requirements change, so always check the current version with the authority concerned. A bill of sale proves transfer of ownership; it is not an airworthiness certificate.
Technical and airworthiness records
Ask for the full set, not a summary:
Certificate of airworthiness and current registration certificate.
Airframe, engine, propeller and APU logbooks.
Component records with times, cycles and calendar limits, including life-limited parts with traceability back to new.
Airworthiness directive compliance records.
Major repairs and modifications, with approved data or supplemental type certificates.
Maintenance program and inspection status; maintenance tracking reports.
Current weight and balance report and equipment list.
Approved flight manual and supplements.
Noise and emissions certificates where required, and radio station licences where applicable.
A maintenance release or return-to-service entry shows that specific work was completed. It does not replace a review of the aircraft's whole history.
Cross-border purchases
When an aircraft changes country, expect additional documents: deregistration confirmation from the exporting state, an export certificate of airworthiness (for example, FAA Form 8130-4 for US exports), import and customs paperwork, tax documentation and evidence that the aircraft meets the importing authority's requirements. An aircraft can be legally bought and still need substantial work before it can be registered and operated in its new country.
Check consistency before you accept
Make sure the registration mark, model, serial number and component serial numbers match across every document. Look for missing logbooks, unexplained gaps in hours or dates, and modifications with no paperwork. Your lawyer and your technical representative should resolve these together before closing.
Frequently asked questions
What is the most important document when buying an aircraft?
There is no single one. A clean title with no outstanding liens and a complete, consistent set of technical records are equally essential.
What happens if logbooks are missing?
Missing records can make it difficult or costly to prove the aircraft's history, may require extra inspections and usually reduce value significantly. Some buyers and lenders will walk away.
Do I need a lawyer to buy an aircraft?
For anything beyond a simple domestic light-aircraft purchase, an aviation lawyer is strongly recommended, and for cross-border or financed transactions it is essential.
