Elements and Performance Criteria

1. Determine requirements
   • Component defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers
   • Components are inspected and/or operated through prescribed test procedures to establish serviceability or confirm defects, as required
   • Modification status is clearly established to assist in determining the overhaul requirements for the components
   • Extent of overhaul or repair is correctly identified and documented
2. Troubleshoot electrical/ electro-mechanical components
   • Available information from maintenance records and test results is used, where necessary, to assist in fault determination
   • Logical processes are used to ensure efficient and accurate troubleshooting
   • Specialist advice is obtained, where required, to assist with, or confirm, the fault and rectification requirement
   • Electrical/electro-mechanical component faults are located and the causes of the faults are clearly identified
   • Fault rectification requirements are determined to assist in planning the repair
3. Dismantle and inspect electrical/ electro-mechanical components
   • Component parts are dismantled in accordance with maintenance manuals while observing all relevant work health and safety (WHS) requirements
   • Component parts are assessed for serviceability in accordance with the relevant maintenance documentation
   • Parts requiring specialist repair are tagged and repair instructions are accurately specified
   • Parts lists are compiled and processed in accordance with standard enterprise procedure
4. Repair and/or modify electrical/ electro-mechanical components
   • Component parts are repaired or replaced in accordance with the relevant maintenance documentation
   • Modification of components or parts is undertaken, where required, by relevant manufacturer's bulletins or procedures
5. Assemble, test and adjust electrical/ electro-mechanical components
   • Assembly of component parts is carried out within specified tolerances and in accordance with the appropriate maintenance documents
   • Components are adjusted or calibrated to operate within prescribed specifications
   • Finished components are tagged, sealed and packaged in accordance with specified procedures
   • Required maintenance documentation and modification records are completed and processed in accordance with standard enterprise procedures

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 repair/overhaul procedures and processes relating to electrical and electro-mechanical components

recognising the serviceability state and repair or overhaul requirements for:

alternating current (AC) and direct current (DC) motors, generators and alternators

static inverters

TRU

regulators/control units

actuators

solenoids and shutoff valves

engine ignition/starting components

applying logic processes, and using test equipment and appropriate wiring diagrams and manuals to isolate component faults

performing component testing to isolate/confirm component fault and assess post-repair/overhaul serviceability

correctly disassembling, inspecting component parts, repairing/replacing/modifying component parts and assembling components listed above.

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

Evidence of transferability of skills and knowledge related to repair is essential. This may be demonstrated through application across a range of aircraft electrical/electro-mechanical components as listed in the Assessment Conditions.
