Description
This unit of competency requires application of hand skills, theory knowledge and maintenance publication procedures to repair and overhaul aircraft gas turbine engine turbine and exhaust section components in workshops during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.Applications include turbine and exhaust section components from turbo-jet, turbofan, turboshaft, turboprop engines and engine modules, or auxiliary power units.The unit is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (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 Turbine and exhaust section components are inspected and/or operated through prescribed test procedures to establish serviceability and confirm defects, if necessary
  • 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 turbine and exhaust section 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 Turbine and exhaust section 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 turbine and exhaust section component parts
  • 3.1 Turbine and exhaust section component parts are dismantled in accordance with maintenance manual while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE)
  • 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 turbine and exhaust section components or parts
  • 4.1 Component parts are repaired or replaced in accordance with the relevant maintenance documentation
  • 4.2 Modification of components is undertaken, where required, by reference to relevant manufacturers’ bulletins or procedures and/or customer requirements
5. Assemble and adjust turbine and exhaust section components
  • 5.1 Turbine and exhaust section component parts are balanced where required and assembled within specified tolerances and in accordance with the appropriate maintenance documents while observing all relevant WHS requirements, including the use of MSDS and items of PPE
  • 5.2 Support/safety equipment, where fitted, is removed at the appropriate time
  • 5.3 Components are adjusted to ensure that fits and clearances are within prescribed specifications
