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.



Safety Risk management is carried out within each of the respective regulatory agencies involved in the UK SSP. These vary based on the size, nature and complexity within the oversight activities of the agency.

The State Safety Board utilises a dashboard to understand the risk associated with each State Safety Objective. These are monitored by safety performance indicators, driven by data, to identify trends and understand emerging risks that appear to ensure that the performance of the UK aviation system is commensurate with the Acceptable Level of Safety Performance.

This is supported by a ‘safety risk wheel’ to depict the risks influencing the UK aviation system. The safety risk wheel goes beyond where the UK has direct regulatory responsibilities and covers activities that fall within three broad areas:

  • Activities which the CAA regulates.
  • Activities within the UK aviation system that the CAA does not directly regulate.
  • International activities outside the direct regulatory control of the UK.

The Regulatory Safety Management System (RSMS) uses a safety risk matrix for assessing, prioritising and managing risks that have been identified internally.

Air Safety Support International maintains a risk profile, which is collated from:

  • Service provider operational information.
  • General UK Overseas Territory data.
  • Foreign national aviation authority reports.
  • Public media sourced information to add to a risk profile.

Defence air safety risks are identified and managed in accordance with MAA RA 1200 - Defence Air Safety Management as part of an effective air safety management system. Those relevant to civil aviation are shared with appropriate organisations outside the defence air environment. The MAA-CAA Memorandum of Understanding (MoU) describes how safety critical information is shared between both parties. The functions of the MoU are facilitated through regular CAA-MAA meetings.
