Overview of assessment

A person who demonstrates competency in this unit must be able to test and troubleshoot a range of instrument and display systems and components that is representative of the scope of the listed variables in accordance with relevant maintenance manual instructions while applying all relevant OHS procedures and standard processes Coverage of display systems is required only where applicable to the enterprise

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 testing and troubleshooting applications including the timely involvement of supervisors or other trades associated with aircraft instrument and display systems and their components It is essential that system testing procedures 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 testing and troubleshooting is essential This may be demonstrated through application across a range of aircraft instrument and display systems where display systems are applicable to the enterprise listed in the Range Statement The application of testing procedures should clearly indicate knowledge of system operation the relationship of individual components and the links with other systems if applicable within the limits of the aircraftsystem faultfinding guide 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 this unit of competency are being achieved under routine supervision on a system and on at least one major system component of each Group to Groups and may be omitted if not applicable to the enterprise 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 work environment or simulated work environment using procedures tools and equipment specified in maintenance documentation It is also expected that general purpose tools test and ground support equipment found in most routine situations would be used where appropriate The level of troubleshooting is limited in its application to the use of fault diagnosis guides or other similar information to enable troubleshooting to line replaceable item level

Method of assessment

Guidance information for assessment

Individuals being assessed who have already attained MEAC Inspect test and troubleshoot advanced aircraft instrument systems will have covered a significant proportion of the Performance Criteria for Elements and 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 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 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 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

Individuals being assessed who have already attained MEA213C Inspect, test and troubleshoot advanced aircraft instrument systems, will have covered a significant proportion of the Performance Criteria for Elements 1, 2 and 3 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, may be accepted as also meeting the evidence requirements for this unit in the applicable areas. The relationship between MEA213C Inspect, test and troubleshoot advanced aircraft instrument systems 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. 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.
