Description
This unit of competency requires application of hand skills and the use of relevant maintenance manuals, drawings and specifications to repair and/or overhaul a range of fixed and rotary wing aircraft mechanical components during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.Components may be from systems such as flight controls, landing gear retraction, nose wheel steering and transmissions other than those that are part of power plant assemblies.This unit of competency is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. The unit 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 Mechanical 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 mechanical 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 Mechanical 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 mechanical component parts
  • 3.1 Mechanical component parts are dismantled in accordance with maintenance manuals 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 (NDT) 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 mechanical
  • 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
