UK Civil Aviation Regulations

These are published by the CAA on our UK Regulations pages. EU Regulations and EASA Access Guides published by EASA no longer apply in the UK. Our website and publications are being reviewed to update all references. Any references to EU law and EASA Access guides should be disregarded and where applicable the equivalent UK versions referred to instead.



To request an Irrevocable De-Registration and Export Request Authorisation (IDERA) the current registered owner of the aircraft will need to complete a CA50 IDERA request form. Once completed, the form should be scanned and emailed to aircraft.reg@caa.co.uk.

Requirements

A request to issue an IDERA must not be made in connection with a pre-existing right or interest. The International Interests in Aircraft Equipment (Cape Town Convention) Regulations 2015 Art 51 offers further information. These Regulations do not apply to a pre-existing right or interest, which retains the priority it enjoyed under the law of the United Kingdom before the effective date of these Regulations.

  • It must be in relation to an 'international interest' which was both created on or after 1st November 2015 and is registered at the International Registry of Mobile Assets.
  • It must be in relation to an aircraft that is covered by the Convention and Protocol; aircraft (other than helicopters) which can carry at least eight people or goods in excess of 2,750 kilograms, and helicopters carrying five or more persons.
  • Only one IDERA can be recorded and current at any one time.

How do I apply?



Complete a CA50: Irrevocable De-Registration and Export Request Authorisation (IDERA) form, which must be completed by the current registered owner of the aircraft. The current registered owner details can be confirmed by entering the registration mark of the aircraft into the at G-INFO UK Register database.

(If the aircraft is not yet registered or a change of registered ownership is pending an IDERA request can be made by the prospective registered owner providing an application to register the aircraft has already been made by the same party.)

It must also be signed by an Authorised Signatory of the registered owner, usually at director or company secretary level. If the form is signed by another party then power of attorney must explicitly empower the signatory to execute the IDERA on behalf of the registered owner.

Once you have completed the form and saved a copy to your device you will then need submit it through the Application Form Submission Service by clicking on the button at the end of the form.
