Unit of competency
Modification History
Release 1 - New unit of competency
Application
This unit of competency requires application of hand skills and the use maintenance publications, applicable materials, tools and methods to repair aircraft composite material structure and components during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.
Applications include composite material structure and components from fixed and rotary wing aircraft either on-aircraft or in the workshop.
The unit is part of the Aeroskills Structures Maintenance Certificate IV training pathway, and of the Mechanical Certificate IV (Aircraft Maintenance Stream) training pathways.
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).
