UK – EU Transition, and UK Civil Aviation Regulations

To access current UK civil aviation regulations, including AMC and GM, CAA regulatory documents, please use this link to UK Regulation. Please note, if you use information and guidance under the Headings, the references to EU regulations or EU websites in our guidance will not be an accurate information or description of your obligations under UK law. These pages are undergoing reviews and updates.

If you are planning to buy an aircraft, or make a loan against one, we advise you to conduct a search of the UK Register of Aircraft Mortgages beforehand. A search of the Register will reveal whether the aircraft is the subject of any registered mortgages. Basic information on whether an aircraft is the subject of a registered mortgage is given on the G-INFO site against each aircraft. However, to get full information on any registered mortgages a mortgage search must be carried out.

Searches are carried out by the CAA on request, and subject to the payment of a fee.

Please note: the Register does not provide information on liens or outstanding debts such as landing fees.

How to request a search of the Register

Using form CA350

Search requests are made using form CA350.

You will need to complete the form and return it to the CAA’s Aircraft Registration Section, along with the appropriate fee. This can be paid by entering your debit/credit card details on the form. The completed form can be emailed to aircraft.reg@caa.co.uk .

The fee is specified in Forms and Fees and also the current CAA scheme of charges.

Turn-around time

We will endeavour to return the results of your search on the same day as your request is made, or the following day. The search includes details of the registered owner, any mortgages entered on the UK Register of Aircraft Mortgages, the parties involved and the date and time of entry.

Opening hours

The Register of Aircraft Mortgages is open between the hours of 10:00 and 16:00 on working days. Searches can only be carried out during these periods. Searches received outside of these hours will be carried out as soon as possible once the Register is open again.
