Unit of competency
Modification History
Release 2. Equivalent to MEA234 Inspect, test and troubleshoot aircraft global navigation systems and components with amended prerequisite codes.
Application
This unit of competency requires application of hand skills and the use of system/component knowledge and applicable maintenance publications and test equipment to inspect, test and troubleshoot global navigation systems (GNS) and components of fixed and rotary wing aircraft during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
The unit is part of the Avionic Certificate IV (Aircraft Maintenance Stream) training pathway.
The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation safety Authority (CASA).
Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.
