Assessment Requirements for MEA223 Inspect aircraft electrical systems and components

Modification History

Release 2. Equivalent to MEA223 Inspect aircraft electrical systems and components with amended prerequisite codes.

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying relevant WHS practices

using approved maintenance documentation and aircraft publications relating to the avionic system being maintained

recognition of system and electrical component defects/external damage, correct installation, connection of plugs, terminations, and attaching hardware (including cabling/harnesses) and security in:

AC and DC power generation systems, including regulation, distribution, control and cooling

battery installations and inverters

flight control and/or electro-hydraulic systems

engine ignition, starting, fuel distribution and control systems

internal/external lighting systems, including controls

doors

landing gear systems

anti-skid braking systems

master caution and warning systems

auxiliary systems (including ice/rain protection, fire detection, environmental control and pressurisation, waste and water, equipment and furnishings).

It is essential that inspection procedures, cleanliness requirements and safety precautions applicable to the electrical system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice (including the timely involvement of supervisors or other trades) 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 Assessment Conditions.

Knowledge Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

component attachment methods and connection of hardware

explaining the basic layout (block diagram level) and operation of:

AC and DC power generation systems, including regulation, distribution, control and cooling

battery installations and inverters

flight control and/or electro-hydraulic systems

engine ignition, starting, fuel distribution and control systems

internal/external lighting systems, including controls

doors

landing gear systems

anti-skid braking systems

master caution and warning systems

auxiliary systems (including ice/rain protection, fire detection, environmental control and pressurisation, waste and water, equipment and furnishings)

WHS requirements applicable to the maintenance of aircraft electrical systems, including gas turbine engine high-energy ignition units

electrical system maintenance requirements

relevant maintenance manuals

relevant regulatory requirements and standard procedures.

Assessment Conditions

Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in the maintenance manuals. It is also expected that applicable general and special purpose tools, and test and ground support equipment would be used where appropriate.

The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.

A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on a system and related components in the following groups:

AC and/or DC power generation, regulation and distribution systems

battery installations and bus ties/interlocks

rotary and static inverters and TR units

air cycle air conditioning and pressurisation systems

flight and engine control systems

ignition and starting systems

fire/smoke detection and extinguishing

lighting

master and caution warning systems

equipment and furnishing

equipment cooling and ventilation

position indicating systems

fuel storage and distribution

propeller control systems (may be omitted if not applicable to the enterprise)

landing gear indication and antiskid (may be omitted if not applicable to the enterprise)

ice and rain protection (may be omitted if not applicable to the enterprise)

wastewater (may be omitted if not applicable to the enterprise).

This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).

Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).

Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.

Individuals being assessed who have already attained MEA294 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 of Conditions variables. The Log of Industrial Experience and Achievement records relating to MEA294 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 MEA294 Inspect, test and troubleshoot advanced aircraft electrical systems and components and MEA210 Inspect, test and troubleshoot basic aircraft electrical systems and components may also be taken into account where MEA210 Inspect, test and troubleshoot basic aircraft electrical systems and components, has been attained, but not MEA294 Inspect, test and troubleshoot advanced aircraft electrical systems and components. Advice in MEA210 Inspect, test and troubleshoot basic aircraft electrical systems and components regarding the coverage of MEA274 Maintain basic light aircraft electrical systems and components, may also be taken into consideration where applicable.
