What an assessment for MEA294 must cover
61 assessable components: 3 elements (12 performance criteria), 16 performance evidence and 33 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 Inspect advanced aircraft electrical systems and components
- 1.1Use required maintenance documentation and modification status, including system defect reports where relevant, to identify specific inspection requirements
- 1.2Check isolation tags and configure aircraft for safe system inspection and operation according to applicable maintenance manual

- 1.4Correctly identify and report defects using organisational reporting processes
2 Test and adjust advanced aircraft electrical systems
- 2.1Prepare aircraft and system according to applicable maintenance manual for the application of power and system operation
- 2.2Functionally test electrical system according to maintenance manual for evidence of serviceability and malfunction
- 2.3Calibrate or adjust system according to maintenance manual, as appropriate
3 Troubleshoot advanced aircraft electrical systems
- 3.1Use available information from maintenance documentation and inspection and test results to assist in fault determination
- 3.2Use maintenance manual fault diagnosis guides and logic processes to ensure efficient and accurate troubleshooting to line replacement level
- 3.3Obtain specialist advice, where required, to assist with troubleshooting process
- 3.4Locate system faults and clearly identify and correctly record causes of faults in maintenance documentation, where required, according to standard organisational procedures
- 3.5Determine rectification requirements according to maintenance requirements
Performance evidence

- electrical components specific to systems, such as air cycle air conditioning, combustion heating, 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.
- prepare for work in line with safety and quality requirements and according to industry, regulatory and organisational requirements, procedures, and methods
- interpret inspection procedures and specifications (allowable limits) and apply them to the inspection, testing, and troubleshooting required in the above work, including seeking the timely involvement of specialist advice
- apply logic processes, taking and interpreting electrical measurements, using test equipment and appropriate wiring diagrams and manuals to isolate electrical system malfunctions in the above systems
- perform system functional tests and checks to isolate system faults and assess post-maintenance serviceability
- apply work health and safety (WHS) requirements applicable to the maintenance of aircraft electrical systems
- use approved maintenance documentation and aircraft publications relating to the electrical system being maintained
- comply with system testing procedures, cleanliness requirements and safety precautions applicable to electrical system being maintained, as well as with work practices associated with electrostatic sensitive devices
- complete and process maintenance documentation.

Questions about assessing MEA294
What does an assessment tool for MEA294 need to cover?
To satisfy the Principles of Assessment and Rules of Evidence, an assessment for MEA294 needs to address all 61 unit components: 3 elements with 12 performance criteria, 16 performance evidence requirements, 33 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 MEA294?
Auditori pulls the current release of MEA294 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 MEA294 — with no card and no subscription required. After that it's pay-as-you-go per unit.
Can I check my existing MEA294 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 MEA294, showing exactly what's covered and what's missing. Mapping costs a quarter of a credit.
