Apply for a Part 66 licence

Once you have met all the Part 66 licence requirements, you can apply:

  • for an initial Part 66 licence
  • to add a category or sub-category to an existing Part 66 licence
  • for an aircraft type rating.

If you have undertaken your licence category training via the Part 147 Maintenance Training Organisation (MTO) pathway, the MTO will notify us on your behalf of the successful completion of your training.

If you have undertaken your licence category training via the Part 66 self-study pathway, we will have a record of the basic knowledge module exams you have successfully passed as part of your training.

Note: Use of any CASA Basics exam credits from an MTO, as part of a licence application, will have to be reported to CASA.

Application fees apply and are outlined in the application forms.

Applying for an initial Part 66 licence

To apply for an initial issue of a Part 66 licence, complete and submit the approved CASA Form to us with any required supporting documents. Instructions on how to submit the application are within the form.

If you completed your training through the Part 66 self-study pathway, please refer to our self-study page for more information.

It is a mandatory requirement for all applicants to have an Australian Reference Number (ARN), prior to applying for a licence. To apply for an ARN, submit an application to us using the approved CASA form.

Apply to add a category or subcategory

To add a category or subcategory to your existing Part 66 aircraft engineer licence, you need to have met both theoretical and practical experience requirements for the category or subcategory of licence you are applying for. See our Part 66 aircraft engineer licence.

To apply, complete and submit the approved CASA Form along with any supporting documents. Instructions on how to submit as well as information on supporting documents are within the form.

In support of your application, you must submit a completed Part 66 aircraft engineer’s basic practical experience logbook, showing evidence of your basic practical experience relevant to the category or subcategory of licence you are applying for.

Apply for an aircraft type rating

To apply for an aircraft type rating endorsement on a licence, complete and submit the approved CASA form to us along with any supporting documents. Instructions on how to submit and information on supporting documents are within the form.

To get an aircraft type rating endorsed on your Part 66 aircraft engineer licence, you need to have completed our approved aircraft type rating course (theory and practical), specific to the aircraft type.

Refer to:

The training needs to have been completed with either an approved Part 147 MTO, an Part 145 approved maintenance organisation (AMO), or other approved maintenance organisation.

If you have undertaken your aircraft type training at an MTO, AMO, or other approved maintenance organisation, the MTO, AMO, or other organisation will notify us on your behalf, of the successful completion of your training, to support your application.
