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 and install components of advanced DC and AC electrical systems while observing all relevant safety precautions

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed understood and complied with as well as work practices associated with electrostatic sensitive devices

Evidence of transferability of skills and knowledge related to removal and installation is essential This is to be demonstrated by application across a range of aircraft major electrical system components encompassing electrical with mechanical interface installations that require alignment andor adjustment mechanical or electrical An understanding of the attachment methods connection of hardware and the need for adjustment or rigging 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 routine supervision on at least one component from each of Groups to and on three components from Group as listed in the Range Statement This shall be established via 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 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

Method of assessment

Guidance information for assessment

Individuals being assessed who have already attained MEAC Remove and install basic aircraft electrical system components will have covered a significant amount of the skill and knowledge requirements for this unit plus part of the Performance Criteria for Elements and and associated Range Statement items Log of Industrial Experience and Achievement records relating to MEAC Remove and install basic aircraft electrical system components may be accepted as also meeting the evidence requirements for this unit in the applicable areas

Individuals being assessed who have already attained MEA202C Remove and install basic aircraft electrical system components, will have covered a significant amount of the skill and knowledge requirements for this unit plus part of the Performance Criteria for Elements 1 and 2 and associated Range Statement items. Log of Industrial Experience and Achievement records relating to MEA202C Remove and install basic aircraft electrical system components may be accepted as also meeting the evidence requirements for this unit in the applicable areas.

Guidance information in MEAC Remove and install basic aircraft electrical system components regarding MEAA Maintain basic light aircraft electrical systems and components should also be taken into consideration and the attainment of MEAA Maintain twin engine aircraft electrical systems and components would significantly increase the extent of coverage of Range Statement variables Log of Experience and Achievement records relating to MEAA Maintain basic light aircraft electrical systems and components and MEAA Maintain twin engine aircraft electrical systems and components may also be accepted as meeting the evidence requirements for this unit in the applicable areas

Guidance information in MEA202C Remove and install basic aircraft electrical system components, regarding MEA274A Maintain basic light aircraft electrical systems and components, should also be taken into consideration and the attainment of MEA277A Maintain twin engine aircraft electrical systems and components, would significantly increase the extent of coverage of Range Statement variables. Log of Experience and Achievement records relating to MEA274A Maintain basic light aircraft electrical systems and components and MEA277A Maintain twin engine aircraft electrical systems and components may also be accepted as meeting the evidence requirements for this unit in the applicable areas.
