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
   • 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

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to repair and overhaul a range of electrical and electromechanical components in accordance with applicable maintenance manuals and regulatoryindustry procedures while observing all relevant safety precautions
Critical aspects for assessment and evidence required to demonstrate competency in this unit	The underlying skills inherent in this unit should be transferable across a range of repair or overhaul applications associated with electricalelectromechanical components listed in the Range Statement It is essential that the maintenance procedures are interpreted and applied to ensure quality and safety standards are fully observed understood and complied with Capability to interpret inspection procedures and specifications allowable limits and apply them in practice 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 electricalelectromechanical components Ability to assess component serviceability and interpret parts requirements will be necessary to supplement the required evidence The application of testing procedures should also clearly indicate knowledge of system operation before undertaking any action Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component faults The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the unit of competency are being achieved under routine supervision on at least one component from each Group to as listed in the Range Statement This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry Evidence Guide
Context of and specific resources for assessment	Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance documentation It is also expected that general and special purpose tools and test equipment would be used where appropriate

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Note	Range statements listed below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide
Electrical/electro-mechanical components	Components may include: 1. Motors, generators, alternators and magnetos (including distributor blocks) 2. Static inverters, TRU and regulators 3. Actuators, solenoids and shutoff valves 4. Bus bars, circuit breakers, connectors, electrical looms and fans
	Application of this unit may relate to: scheduled or unscheduled maintenance individual or team-related activities complex testing and adjusting of components, and where this is undertaken, may be carried out under supervision at the appropriate level
Procedures and requirements	Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise
