Elements and Performance Criteria

1. Assess requirements for NDT
   • The inspection area is assessed for testing and all possible failure sites identified using metallurgical analysis
   • Information relevant to test development is collected from available sources using accepted techniques
   • Information is analysed and interpreted
2. Test requirements are determined
3. Evaluate NDT techniques and procedures
   • Test methods, techniques and procedures for specific NDT tasks are specified
   • Applicable codes, standards, specifications and procedures are interpreted
   • Test procedures are developed in accordance with established techniques and metallurgical principles
4. Validate/confirm NDT tasks
   • General and specific test procedures are validated in accordance with established techniques
   • Inspection results are interpreted in accordance with existing codes, standards and specifications
5. Evaluate NDT test procedures
   • Procedures are evaluated for effectiveness
   • Evaluation results are documented and reported in accordance with standard enterprise procedures
   • Changes/amendments to NDT procedures are made and distributed 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 nondestructive 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 supervisors 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 nondestructive tests or other units requiring the exercise of the skills and knowledge covered by this unit
