Unit of competency
Modification History
Release 2. Equivalent to MEA424 Evaluate aircraft non-destructive tests with amended prerequisite codes.
Application
This unit of competency requires application of competencies relating to non-destructive testing (NDT) techniques and related metallurgical knowledge in the research, analysis, development and evaluation of NDT tests for aircraft structure and components to Level 3 (AS 3669-2006 Non-destructive testing – Qualification and approval of personnel – Aerospace) during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
The work can relate to scheduled and unscheduled maintenance activities on the metallic and composite structure of aircraft and aircraft components
Certification against applicable standards may be achieved where assessment in this unit of competency is carried out in conjunction with an examining authority as described in ISO 9712:2005 Non-destructive testing – Qualification and certification of personnel.
The unit is part of the Diploma and Advanced Diplomas of Aeroskills (Non-Destructive Testing). The unit is similar to unit MEM24011B Establish non-destructive tests but observes the requirements of AS 3669-2006 Non-destructive testing – Qualification and approval of personnel – Aerospace and of the Regulators; the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA); for the approval of procedures and the performance of NDT on aircraft and aircraft components.
