Modification History
Knowledge statements expanded - equivalent to previous unit.
Unit Descriptor
This unit of competency is part of the Avionic Certificate IV (Aircraft Maintenance Stream) training pathways and is also part of the Mechanical Aircraft Maintenance Engineer licensing pathway. It covers the competencies required to inspect electrical systems and components of fixed and rotary wing aircraft. The unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.
Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen B1 or the B2 maintenance certification licence under CASR Part 66, in accordance with the licensing provisions in Section 3, Assessment Guidelines.
Application of the Unit
This unit requires application of hand skills and the use of system/component knowledge and applicable maintenance publications to inspect aircraft electrical systems and components.
Applications include fixed and rotary wing aircraft.

Overview of assessment |
A person who demonstrates competency in this unit must be able to inspect aircraft electrical 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 electrical 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 electrical systems, components and hardware 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 related components in each Group 1 to 13 inclusive (Groups 14 to 17 may be omitted where they are not applicable to the enterprise) 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. |

Guidance information for assessment |
Individuals being assessed who have already attained MEA211C Inspect, test and troubleshoot advanced aircraft electrical 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 MEA211C Inspect, test and troubleshoot advanced aircraft electrical systems and components may be accepted as also meeting the evidence requirements for this unit in the applicable areas. The relationship between MEA211C Inspect, test and troubleshoot advanced aircraft electrical systems and components and MEA210C Inspect, test and troubleshoot basic aircraft electrical systems and components may also be taken into account where MEA210C Inspect, test and troubleshoot basic aircraft electrical systems and components, has been attained, but not MEA211C Inspect, test and troubleshoot advanced aircraft electrical systems and components. Advice in MEA210C Inspect, test and troubleshoot basic aircraft electrical systems and components regarding the coverage of MEA274A Maintain basic light aircraft electrical systems and components, may also be taken into consideration where applicable. |
Range Statement
The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included. |
