Description
This unit of competency requires application of hand skills, the use of maintenance publications, and knowledge of gas turbine engine and system theory to test and troubleshoot gas turbine engines and engine system components of fixed and rotary wing aircraft during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.The unit is part of the Mechanical Aircraft Maintenance Engineer (AME) Certificate IV training pathways and must be taken with MEA319 Inspect gas turbine engine systems and components. 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.
