Mandatory units

Human factors in aviation

Fundamentals of electronics and avionics

Aerodynamics and control in a fixed-wing aircraft

Structural materials and components in aircraft

Aviation mathematics and science for technicians

Then the college can elect to chose either

And

or Maintaining gas turbine engines and rotors.

UK Regulation (EU) No. 1321/2014 (amending Regulation (EC) No 2042/2003) states, the basic examinations shall be passed, and experience shall be acquired within the ten years preceding the application for an aircraft basic licence.

Please note, EASA Certificates of Recognition validity cannot be extended. 

The UK is unable to accept any EASA Part 147 Certificate of Recognition dated after 31st December 2022.

The end of the Withdrawal Agreement on this date, removed the legal basis for these certificates in the UK, therefore the CAA has no legal power to accept any certificated dated after this date.

Basic module and basic course certificates will continue to be accepted up to 10 years after their issue date, when issued before 31st December 2022.

Type rating certificates will continue to be accepted up to 3 years after their issue date, when issued before 31st December 2022.

Any certificate dated after 31st December 2022, must have been issued by a UK Part 147 Maintenance Training Organisation which can be found located internationally.

For all licences other than Category L, Appendix II to Part 66 requires essay questions for Modules 7A, 7B, 9A, 9B and 10. Basic Examination Standard (except for category L licence) paragraph 1.4.

Exam questions should be written so as to be broad enough to be answered by candidates for any A or B licence category or subcategories, be on a generic topic to allow answering by both mechanical and avionic licence category students, cover technology relevant to most areas of maintenance, reflect common working practices, be type and manufacturer agnostic and accessible to candidates with limited practical experience. GM 66.B.200 Examination by the CAA paragraph 6(b)

Therefore, examinations for essays are not specific for Category A or B licence and an essay pass at Category A level is considered equivalent to a pass at Category B allowing the module Certificate of Recognition to be used to apply for either Category A or B licences.
