Description
This unit of competency is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It covers the competencies required to overhaul and repair a range of aircraft fuel system components. This unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.
Notes
Elements and Performance Criteria
1. Determine requirements
- 1.1. Component defect reports (removal tags) or customer order are correctly interpreted and matched by part and serial numbers
- 1.2. Fuel system components are inspected and/or operated through prescribed test procedures to establish serviceability or confirm defects, as required
- 1.3. Modification status is clearly established to assist in determining the overhaul requirements for the components
- 1.4. Extent of overhaul or repair is identified and documented in accordance with standard enterprise procedures
2. Troubleshoot fuel system components
- 2.1. Available information from maintenance records and test results is used, where necessary, to assist in fault determination
- 2.2. Logical processes are used to ensure efficient and accurate troubleshooting
- 2.3. Specialist advice is obtained, where required, to assist with, or confirm, the fault and rectification requirement
- 2.4. Fuel system component faults are located and the causes of the faults are clearly identified
- 2.5. Fault rectification requirements are determined to assist in planning the repair
3. Dismantle and inspect fuel system component parts
- 3.1. Fuel system component parts are dismantled in accordance with maintenance manuals
- 3.2. Component parts are assessed for serviceability in accordance with the relevant maintenance documentation
- 3.3. Parts requiring specialist repair are tagged and repair instructions are specified in accordance with standard enterprise procedures
- 3.4. Parts requiring non-destructive testing are prepared for testing in accordance with the relevant maintenance documentation
- 3.5. Parts lists are compiled and processed in accordance with standard enterprise procedures
4. Repair and/or modify fuel system components or parts
- 4.1. Component parts are repaired or replaced in accordance with the relevant maintenance documentation
- 4.2. Modification of components or parts is undertaken, where required, by relevant manufacturer's bulletins or procedures
5. Assemble, test and adjust fuel system components
- 5.1. Fuel system component parts are assembled within specified tolerances and in accordance with the appropriate maintenance documents
- 5.2. Components are adjusted, tested or calibrated to operate within prescribed specifications
- 5.3. Finished components are tagged, sealed and packaged in accordance with standard enterprise procedures
- 5.4. Required maintenance documentation and modification records are completed and processed in accordance with standard enterprise procedures
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.

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 apply hand skills and component theory knowledge and use maintenance publications to repair and overhaul aircraft fuel system components while applying 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 and/or overhaul applications associated with aircraft components. It is essential that the maintenance procedures are interpreted and applied to ensure quality and safety standards are achieved.
Evidence of transferability of skills and knowledge related to repair is essential. This may be demonstrated through application across a number of different aircraft components. Ability to assess component serviceability and interpret parts requirements will be necessary to supplement the required evidence. Capability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical. The application of testing procedures should also clearly indicate knowledge of system operation. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot component faults before undertaking any action. 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 of Groups 1 and 2 in the Range Statement including demonstration of the applicable repair processes listed in Groups 3 to 9. 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 purpose tools and test equipment found in most routine situations would be used where appropriate.
