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 inspect test and troubleshoot aircraft instrument systems and components while observing 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 across a range of inspection applications including the timely involvement of supervisors or other trades associated with aircraft instrument systems and components It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed understood and complied with Ability to interpret inspection procedures and specifications allowable limits and apply them in practice is critical

Evidence of transferability of skills and knowledge related to inspection is essential This is to be demonstrated through application across a range of aircraft instrument systems and components listed in the Range Statement 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 system and at least one major system componentLRU from each of Groups to Group may be omitted where it is not applicable to the enterprise 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 the maintenance manuals It is also expected that general and special purpose tools test and ground support equipment would be used where appropriate

Method of assessment

Guidance information for assessment

Individuals being assessed who have already attained MEAC Inspect test and troubleshoot advanced aircraft instrument systems and components will have covered a significant proportion of the Performance Criteria for Element and will have covered many of the Range Statement variables Log of Industrial Experience and Achievement records relating to MEAC Inspect test and troubleshoot advanced aircraft instrument systems and components may be accepted as also meeting the evidence requirements for this unit in the applicable areas

Individuals being assessed who have already attained MEA213C Inspect, test and troubleshoot advanced aircraft instrument systems and components, will have covered a significant proportion of the Performance Criteria for Element 1 and will have covered many of the Range Statement variables. Log of Industrial Experience and Achievement records relating to MEA213C Inspect, test and troubleshoot advanced aircraft instrument systems and components, may be accepted as also meeting the evidence requirements for this unit in the applicable areas.

The relationship between MEAC Inspect test and troubleshoot advanced aircraft instrument systems and components and MEAC Inspect test and troubleshoot basic aircraft instrument systems and components may also be taken into account where MEAC Inspect test and troubleshoot basic aircraft instrument systems and components has been attained but not MEAC Inspect test and troubleshoot advanced aircraft instrument systems and components Advice in MEAC Inspect test and troubleshoot basic aircraft instrument systems and components regarding the coverage of MEAA Maintain basic light aircraft instrument systems and components may also be taken into consideration where applicable

The relationship between MEA213C Inspect, test and troubleshoot advanced aircraft instrument systems and components, and MEA212C Inspect, test and troubleshoot basic aircraft instrument systems and components may also be taken into account where MEA212C Inspect, test and troubleshoot basic aircraft instrument systems and components has been attained, but not MEA213C Inspect, test and troubleshoot advanced aircraft instrument systems and components. Advice in MEA212C Inspect, test and troubleshoot basic aircraft instrument systems and components regarding the coverage of MEA275A Maintain basic light aircraft instrument systems and components, may also be taken into consideration where applicable.
