If your Part 66 licence includes exclusions, you can remove them by completing additional knowledge, experience and assessment requirements. This allows you to expand the certification privileges of your licence.
To remove an exclusion, apply to CASA. Follow these steps:
You need to identify the exclusion from your licence.
You need to complete required exams and experience.
Submit your application using:
An exclusion is a limitation on your licence. It excludes you from certifying maintenance on an aircraft system where you have not demonstrated the required knowledge and experience, such as training and practical experience.
There are 2 pathways to remove an exclusion from a licence category:
A Part 147 MTO (approved by us to conduct licence category training) can provide exclusion removal:
Contact an MTO to discuss the exclusion you want to remove and required training.
Complete the relevant units of competency (see Appendix VIII of the Part 66 MOS).
Sit module exams specified by the MTO.
Once your training and assessment has been reported to CASA by the MTO, submit your application to us.
If you choose to use this pathway, you will need to demonstrate both knowledge and practical experience.
Pass the relevant basic knowledge module exam(s) (see tables below).
Record relevant maintenance experience in your:
You must include evidence of work performed on the excluded system.
Note: Part 66 modular licence holders must still meet the required practical experience duration – see Table 3A and clause 66.A.30(ba) of the Part 66 Manual of Standards - when seeking to remove at least one aircraft system or subsystem exclusion from their licence to gain an extension of licence privileges.
When you submit your application to us, make sure you include your:
