What an assessment for MEA203 must cover
24 assessable components: 2 elements (8 performance criteria), 5 performance evidence and 11 knowledge evidence requirements. An audit-defensible tool maps every question and task back to these — that mapping is the coverage matrix Auditori generates alongside the assessment.
Elements & performance criteria
1 Remove AC and DC aircraft electrical system components
- 1.1System is rendered safe and prepared in accordance with the applicable maintenance manual and isolation tags are fitted, where necessary, to ensure personnel safety
- 1.2Electrical component removal is carried out in accordance with the applicable maintenance manual while observing all relevant work health and safety (WHS) requirements
- 1.3Required maintenance documentation is completed and processed in accordance with standard enterprise procedures
- 1.4Removed components are tagged and packaged in accordance with specified procedures
2 Install AC and DC aircraft electrical system components.
- 2.1Electrical components to be installed are checked to confirm correct part numbers, modification status, serviceability and shelf life
- 2.2Physical installation of electrical components is performed in accordance with the applicable maintenance manual, ensuring appropriate adjustment/alignment with mechanical interface is carried out
- 2.3System is reinstated to correct operational condition in preparation for testing, as necessary
- 2.4Required maintenance documentation is completed and processed in accordance with standard enterprise procedures
Performance evidence
- 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
- 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)).

Questions about assessing MEA203
What does an assessment tool for MEA203 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEA203 needs to address all 24 unit components: 2 elements with 8 performance criteria, 5 performance evidence requirements, 11 knowledge evidence requirements, and the foundation skills. A coverage matrix mapping each question and task to these components is what an auditor looks for.
How does Auditori generate an assessment tool for MEA203?
Auditori pulls the current release of MEA203 from training.gov.au and generates a complete package: candidate assessment, assessor guide with model answers and observation criteria, and a coverage matrix mapping every component. A suitably qualified person then reviews and approves the draft in a built-in workflow — consistent with ASQA's guidance on AI use in VET — before export as branded PDF and editable Word.
Is the first assessment tool really free?
Yes. Every new account includes one free credit — enough to generate the complete assessment tool for MEA203 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEA203 assessment instead of generating a new one?
Yes — upload your existing assessment or learner guide and Auditori maps it against every element, performance criterion, PE and KE of MEA203, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
