Unit of competency
Modification History
Release 1. Application changed. Elements and Performance Criteria changed. Foundation Skills made explicit. Assessment Requirements clarified. Supersedes and is equivalent to MEA424 Evaluate aircraft non-destructive tests.
Application
This unit describes the skills and knowledge required to apply non-destructive testing (NDT) techniques and related metallurgical knowledge to research, analyse, develop and evaluate 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. 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.
The unit is used in workplaces that operate under the airworthiness regulatory systems of the Civil Aviation Safety Authority (CASA) and the Defence Aviation Safety Authority (DASA).
Any other relevant legislation, industry standards and codes of practice within Australia must be applied.
