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.



It is the CAA’s Aviation Security Department’s policy to ensure the fair and equitable interpretation, understanding and application of regulation to improve the effective and high quality delivery of aviation security training.

We are responsible for:

  • Developing, with industry, new or revised syllabuses for aviation security training and submitting these to Department for Transport (DfT) for approval.
  • Maintaining and managing the UK list of certificated instructors (an individual who has met the criteria, issued with a Certificated Instructor Number (CIN) and listed on the CAA website).
  • Management of the Quality Assurance Framework, including the registration of training providers, support to industry in implementing/maintaining internal quality assurance of training and administration of the external quality assurance visit of training providers.
  • Maintaining and managing test managers of the UK National X-ray Competency Test (NXCT).

The training team within CAA Aviation Security Regulation (AvSec), is the industry point of contact for requests for instructor certification, National X-ray Competency Test (NXCT) test managers, registration of training providers and provides regulatory information and advice, in addition to making recommendations to the Department for Transport (DfT) for suitability for such approvals.
