Assessment Requirements for MEA203 Remove and install advanced aircraft electrical system components

Modification History

Release 1 - New unit of competency

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 include:

identifying/locating:

DC power regulation, distribution and control systems and components, i.e. regulators and bus bars

AC power regulation, distribution and control systems and components, i.e. generator control units

various types of inverters and transformer rectifier units

gas turbine and piston engine ignition and starting systems and components (where applicable to the enterprise)

batteries (lead acid and nickel cadmium) and associated mounting equipment including related anti-vibration aids and battery temperature monitoring systems

flight control servo actuating devices, i.e. AC and DC electro-mechanical, electro-pneumatic, electro-hydraulic, duplex servomotors, power control units and trim control devices

electrical components of aircraft systems, such as air cycle air conditioning, anti-icing and de-icing, landing gear, anti-skid, flight control, master and central warning, fuel storage and distribution, external and internal lighting, fire warning and extinguishing, and engine/propeller control (where applicable to the enterprise)

correctly connecting:

DC generators

star or delta alternators to star and delta loads

starter generators

AC motors

polyphase motors

applying relevant WHS practices.

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 and installations that require alignment and/or adjustment (mechanical or electrical).

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

connection of hardware and plugs

relevant WHS practices

the use of approved maintenance documentation and aircraft publications relating to AC and DC electrical systems

properties of permanent magnets

precautions for the care and storage of permanent magnets

bonding of aircraft components and lightning protection

general construction, operating characteristics and applications for aircraft:

generators

alternators

AC and DC motors

transformer rectifier units

rotary and static inverters

batteries

linear and rotary actuators

relevant maintenance manuals

relevant regulatory requirements and standard procedures

environmental protection requirements relating to Halon fire extinguishers (e.g. Bromochlorodifluoromethane (BCF)).

Assessment Conditions

Competency should be assessed in the work environment or simulated work environment, using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine maintenance situations would be used where appropriate.

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.

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 at least one (1) component from:

DC and AC power generation and distribution system components, including generators and related multi-sourced DC power generation, starter generators alternators and regulation, and control and distribution system components

transformer rectifier units and/or inverters

batteries and related bus tie or interlock system components and battery temperature monitoring systems

motors and actuators

components of gas turbine and/or piston engine ignition and starting systems (may be omitted where not applicable to the enterprise)

external/internal lights

and on three (3) components that are applicable to the enterprise from:

electrical components of specific electrical systems, such as air cycle air conditioning, combustion heaters, equipment cooling, anti-icing and de-icing, landing gear, anti-skid, flight control, master and central warning, fuel storage and distribution, fire warning and extinguishing and engine/propeller control.

This shall be established via 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 MEA202 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 of conditions items. The Log of Industrial Experience and Achievement records relating to MEA202 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 MEA202 Remove and install basic aircraft electrical system components regarding MEA274 Maintain basic light aircraft electrical systems and components should also be taken into consideration and the attainment of MEA277 Maintain twin engine aircraft electrical systems and components would significantly increase the extent of coverage of range of conditions variables. The Log of Experience and Achievement records relating to MEA274 Maintain basic light aircraft electrical systems and components and MEA277 Maintain twin engine aircraft electrical systems and components may also be accepted as meeting the evidence requirements for this unit in the applicable areas.
