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.



The UK Civil Aviation Authority (CAA) and the Spanish Aviation Safety and Security Agency (AESA) have today signed a Memorandum of Understanding (MoU) to engage in the development and promotion of aviation safety and security standards globally.

The MoU supports both parties to work together on areas of mutual interest and use their technical capabilities to contribute to improving air transport safety and security. This will include exchanging ideas, information, skills, and techniques.

Building on an already established relationship, the MoU sets a foundation for long-term collaboration between the UK and Spain on aviation safety performance.

The MoU also supports cooperation on international cooperation projects through their affiliated entities, CAA International and SENASA.

A copy of the MoU is available.
