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 to remove and install propellers and propeller system components on propellerdriven fixed wing aircraft 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 units that require similar techniques It is essential that shoring trestling and lifting requirements and safety precautions applicable to propeller system maintenance are fully observed understood and complied with and that an awareness is demonstrated of dual inspection requirements Evidence of transferability of skills and knowledge related to removal and installation is essential This may be demonstrated through application across a representative range of propeller system components An understanding of component attachment methods the need for adjustment or rigging and system operation as it relates 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 routine supervision on at least one item from each of Groups to in the Range Statement Group may be omitted where it is not applicable to the enterprise 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 aircraft maintenance manuals It is also expected that general purpose tools test and ground support equipment found in most routine situations would be used where appropriate
