Application
This unit of competency describes the skills and knowledge required to maintain basic avionic systems and components. It involves inspecting, testing and troubleshooting systems; and removing and installing components. The unit requires the application of hand skills and the use of maintenance documentation and publications. Work may be performed individually or as part of a team.
The unit applies to the scheduled and unscheduled maintenance of basic fixed wing and rotary wing aircraft where the avionic systems are limited to very high frequency (VHF) communications, basic audio systems, automatic direction finding (ADF) and very high frequency omni-range (VOR) radio navigation systems, stand-alone global navigation systems (GNS), air traffic control (ATC) transponders, and automatic dependent surveillance-broadcast (ADS-B).
This unit forms part of the Civil Aviation Safety Authority (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.
