Elements and Performance Criteria

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Application
Application of this unit may relate to:
standard practices for structural repair and modification, including damage measurement and assessment against approved repair schemes
the process for referral of damage details and modification requirements to relevant personnel/authorities
supervision of repair scheme and modification incorporation, including evaluation of work against drawings and specifications
scheduled or unscheduled maintenance
individual activities or supervision of other personnel performing maintenance tasks which may include:
non-destructive inspection
welding
surface plating
surface finishing
preparing structural repair components
machining
Dye penetrant NDT procedures
Surfaces to be inspected are prepared by:
removal of surface finishes where applicable
thorough cleaning of the surface
drying of the surface
processes included in standard procedures
Dye penetrant materials
Dye penetrant materials may include:
appropriate surface cleaning materials
emulsifiers
developers
materials for surface cleaning after testing
Procedures and requirements
Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

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 determine structural repair and modification requirements using maintenance manuals, modification instructions and applicable drawings, and must be able to assess the soundness of weld repairs while identifying all safety precautions relevant to specified structural repair or modification tasks and must also be able to perform colour contrast dye penetrant NDT on relevant aircraft components.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The underlying skills inherent in this unit should be transferable across a range of repair and modification applications related to the structure of aircraft. It is essential that the repair and modification procedures take into account all applicable safety precautions. The ability to interpret repair scheme and modification requirements, including applicable specifications (allowable limits) and ensure that they are applied in practice is critical.
Evidence of transferability of skills and knowledge related to structural maintenance is essential. This must be demonstrated through the correct determination of repair requirements and the determination of compliance with repair schemes and modification drawings. The ability to assess sound weld repairs must also be demonstrated. Applicable work plans should take account of applicable safety (including safe handling of heavy components) and quality requirements in accordance with the industry and regulatory standards.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the elements of the unit of competency are being achieved under supervision without intervention. This shall be established via simulated activities at the CASR Part 147 MTO and performance during observed workplace activities.
Context of and specific resources for assessment
Competency will be assessed in the training environment using a combination of practical exercises and scenarios.
