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.

This page provides information to applicants wanting to apply for a UK Part 147 approval to carry out basic and/or aircraft type training for Part 21 aircraft.


How do I apply?

Complete the Part 147 application form and submit with the supporting documents using the Application Form Submission Service portal at the end of the form.

Close How do I apply?

How much does it cost?

The cost depends on several factors, including the aircraft Maximum Take-Off Weight (MTOW).

If you apply for an initial approval with multiple ratings under the same approval type, you must include a payment relating to the charge for the highest rating applied for, for example, a Part 147 application for ratings T1, T2 and C would attract a single charge for the highest rating, being the T1, as per the Scheme of Charges.

The list of Official Record Series 5 explains the Civil Aviation Authority (CAA) Scheme of Charges.

In the event of a discrepancy between the information here and the Official Record Series 5, CAA Scheme of Charges (Airworthiness, Noise Certification and Aircraft and Aircraft Engine Emissions), the Scheme of Charges takes precedence.
