Unit of competency
Modification History
Release 2. Equivalent to MEA412 Pre-treat aluminium alloy surfaces with amended prerequisite codes.
Application
This unit of competency requires application of skills and knowledge relating to the application of chemical conversion coatings to aluminium alloy surfaces of fixed and rotary wing aircraft and aircraft components with aluminium alloy surfaces during the performance of scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
No licensing requirements apply to this unit at the time of publication, but requirements for compliance with legislation and regulations for the handling and disposal of hazardous materials is included in the unit.
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).
