This unit describes the skills and knowledge required to select aeronautical engineering materials and materials tests, source materials data, ensure appropriate performance and physical standards for mechanical or avionic applications, document materials tests, ensure calibration standards and interpret and document materials data sheets for mass production, batch production, jobbing shop and prototyping applications.

This unit applies to design and development or aeronautical engineering support team workers selecting and testing mechanical or avionic engineering materials according to established procedures, industry standards and regulatory requirements.

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).

Where a CASA or DASA licensing outcome is sought this unit forms part of the requirement for the granting of the chosen maintenance certification licence under the relevant Aviation Safety Regulations, in accordance with the licensing provisions in the MEA Aeroskills Companion Volume Implementation Guide.

Any other relevant legislation, industry standards and codes of practice within Australia must be applied.
