This page provides information to applicants wishing to apply for a UK Part 145 approval to maintain UK registered Part 21 aircraft and/or the engines and components fitted to them.
Pre-Requisites
Organisations should have their principal place of business in the UK.
Organisations with their principal place of business located outside the UK, should apply for a UK Third Country Approval.
Organisations needing to change a Registered Company or Limited Liability Partnership (LLP) Number will require a new initial approval as it cannot be classed as a change to an existing approval. Leaflet C-30 (CAP 562) provides further information.
How do I apply?
Complete the Part 145 online application form.
Unfortunately, our online application form is limited to only letting organisations add up to six aircraft types on the application form. In cases where organisations wish to add more types, we kindly request that you submit your application online with as much detail as you can, and then follow up with an email listing all of the types you want on your approval. The email should be sent to apply@caa.co.uk and should quote the online application reference number.
How much does it cost?
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 145 application for ratings A2, A3 and B1 would attract a single charge for the highest rating, being the B1, as per the Scheme of Charges.
The Official Record Series 5, Civil Aviation Authority (CAA) Scheme of Charges provides further details.
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.
