Application
This unit requires application of competencies relating to 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).
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.

4.2 | Evaluation results are documented and reported in accordance with standard enterprise procedures | ||
4.3 | Changes/amendments to NDT procedures are made and distributed in accordance with standard enterprise procedures |
Required Skills
Look for evidence that confirms knowledge of: definition of structural terms, i.e. safe life, damage tolerant, failsafe, stress, strain, shear and cycles inspection requirements for metal and composite structure, including: ageing aircraft inspection requirements safe life structure damage tolerant structure fail safe structure potential causes of structural failure metallurgical analysis to assess inspection areas and potential failure sites and modes NDT methods, techniques and procedures meaning and validity of relevant codes, standards, specifications and procedures regulatory requirements of the ADF and CASA relating to the use of NDT for inspection of aircraft structure and components test procedure for testing techniques and specimen validation processes process for approval of procedures process for documentation/distribution of procedures evaluation procedures process for documentation of evaluation results process for amending tests and distributing amendments national/Australian standards, NOHSC guides, state/territory regulatory codes of practice/standards use and application of personal protective equipment safe work practices and procedures relevant hazards and control measures related to the competency Look for evidence that confirms skills in: conducting metallurgical assessment of inspection areas and identifying potential failure sites and modes designating most appropriate method, technique or procedure referencing aircraft maintenance information and regulatory requirements for inspection developing and validating test procedures applying safety procedures, standard operating procedures and legislative requirements to all work reading/interpreting/applying relative testing standards reading/interpreting/applying relative conformance standards documenting procedure and results submission of reports in accordance with standard enterprise procedures |
Evidence Required
The evidence guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package. | |
Overview of assessment | A person who demonstrates competency in this unit must be able to establish and evaluate non-destructive tests for aircraft structure and components. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | Assessors should gather a range of evidence that is valid, sufficient, current and authentic. Evidence can be gathered through a variety of ways including direct observation, supervisor’s reports, project work, samples and questioning. Questioning techniques should not require language, literacy and numeracy skills beyond those required in this unit of competency. The candidate must have access to all tools, equipment, materials and documentation required. The candidate must be permitted to refer to any relevant workplace procedures, product and manufacturing specifications, codes, standards, manuals and reference materials. Assessors must be satisfied that the candidate can competently and consistently perform all elements of the unit as specified by the criteria, including required knowledge, and be capable of applying the competency in new and different situations and contexts. |
Context of and specific resources for assessment | This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is the candidate is not in productive work, then an appropriate simulation must be used where the range of conditions reflects realistic workplace situations. The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team. The assessment environment should not disadvantage the candidate. |
Method of assessment | This unit could be assessed in conjunction with any other units addressing the safety, quality, communication, materials handling, recording and reporting associated with the research, analysis, development, approval and evaluation of non-destructive tests, or other units requiring the exercise of the skills and knowledge covered by this unit. |
