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 remove light corrosion from the surfaces of aircraft structure in accordance with specified procedures while using the correct PPE and observing all relevant safety precautions and environmental protection processes

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 tasks involving the removal of light corrosion damage from the surfaces of aircraft structure It is essential that applicable processes cleanliness requirements and safety precautions including the correct use of PPE and application of environmental protection procedures are fully observed understood and complied with Ability to interpret corrosion removal procedures and apply them in practice is critical

Evidence of transferability of skills and knowledge related to the removal of light corrosion is essential This is to be demonstrated through corrosion removal using mechanical manual and chemical means across a range of aircraft tasks 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 a representative range of light corrosion removal tasks using applicable mechanical manual and chemical removal methods as 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 materials tools and equipment specified in the maintenance manuals and applicable procedures It is also expected that general and special purpose tools and ground support equipment would be used where appropriate
