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 use specialist tools and use maintenance publications to remove and install items of general aircraft electrical hardware that are within the privileges of the CASA Aircraft Maintenance Engineer A Licence while observing all relevant safety precautions
Critical aspects for assessment and evidence required to demonstrate competency in this unit	It is essential that applicable cleanliness requirements and OHS safety precautions are fully observed including awareness of electrostatic discharge procedures Evidence of transferability of skills and knowledge related to removal and installation is essential An understanding of the attachment methods connection of hardware and system operation as they relate to the work must be demonstrated before undertaking any action The work plan should take account of applicable safety 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 relevant elements of the unit of competency are being achieved under supervision but without intervention on each of the connection methods and listed 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 workplace or simulated workplace using tools and equipment specified in maintenance manuals It is also expected that generalpurpose tools test and ground support equipment found in most routine situations would be used where appropriate
