Unit of competency
Modification History
Release 2. Equivalent to MEA368 Shot peen aircraft components with amended prerequisite codes.
Application
This unit of competency requires application of hand skills and the use of relevant process documentation to shot peen aircraft components, such as structural components and components of engines, propellers and landing gear shock struts from fixed and rotary wing aircraft during scheduled or unscheduled maintenance.
The unit is part of the Mechanical Certificate IV training pathway and is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
