The L1 Maintenance Authority is a compulsory requirement if you wish to maintain your own aircraft. If you do not perform any maintenance on your aircraft above the definition for Line Maintenance as per section 12.7 of the RAAus Technical Manual, this course is not required to be completed.
We've streamlined the enrolment and assessment process so that your progress can be linked to your records, however you will still need to register an account in the Learning Management System (LMS).
