Application
This unit of competency describes the skills and knowledge required to inspect, test and troubleshoot advanced aircraft electrical systems and components. It involves the application of hand skills and the use of system and component knowledge and applicable maintenance publications and test equipment when working with the systems and components of fixed and rotary wing aircraft that have advanced electrical systems, during scheduled and unscheduled maintenance. Work may be performed individually or as part of a team.
The unit is part of the Mechanical Aircraft Maintenance Engineer licensing pathway. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
This unit forms part of the CASA requirement for maintenance certification licences under Civil Aviation Safety Regulation (CASR) Part 66. Where a CASA licensing outcome is sought, users must refer to the licensing provisions in the MEA Aeroskills Companion Volume Implementation Guide.
