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 apply hand skills and use maintenance publications and modification instructions to correctly fit small aircraft avionic modification sheetmetal components while applying all relevant safety precautions
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The underlying skills inherent in this unit should be transferable into other areas that require similar techniques It is essential that procedures take into account all safety precautions and quality requirements standards and practices and processes associated with assembly Evidence of knowledge about enterprise procedures relating to avionic modification incorporation and practices relating to associated sheetmetal component installation will be necessary to supplement evidence of ability to fit a range of sheetmetal components in a specific application A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the unit of competency are being achieved under qualified person guidance on the range of sheetmetal components listed in Groups to in the Range Statement This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry Evidence Guide
Context of and specific resources for assessment	Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance documentation It is also expected that general purpose tools and test equipment found in most routine situations would be used where appropriate

Range Statement

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.
Note	Range statements listed below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide
Sheetmetal components	Sheetmetal components may include: 1. Doublers for the installation of antennas 2. Brackets for the installation of avionic system components 3. Racks for components, such as transmitters/receivers 4. Hardware for the support of antenna cables and system electrical wiring
	Application of this unit may relate to: scheduled or unscheduled maintenance individual or team-related activities
Procedures and requirements	Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise
