Elements and Performance Criteria

1. Fabricate mechanical components or parts
   • Specifications are interpreted to determine the dimensions and procedure for fabrication
   • Appropriate materials, tools, equipment and assembly or fabrication jigs are selected and prepared for the particular specification requirements
   • Components or parts are fabricated in accordance with required specifications 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)
   • Test equipment and rigs are used, where applicable, to confirm serviceability of finished components
   • Fabricated components are tagged, sealed and packaged within specified procedures
   • Required maintenance documentation is completed and processed in accordance with standard enterprise procedures
2. Repair mechanical components or parts
   • Repair or replacement requirements are determined, following disassembly and assessment of component parts for serviceability, in accordance with the relevant maintenance documentation while observing all relevant WHS requirements, including the use of MSDS and items of PPE
   • Tagging and repair instructions are accurately specified for parts requiring specialist repair
   • Components are modified, as approved, by relevant manufacturers’ bulletins or procedures
   • Mechanical component parts are assembled within specified tolerances and in accordance with the appropriate maintenance documents
   • Mechanical components are adjusted, as required, to operate within prescribed specifications
   • Repaired components are tagged, sealed and packaged in accordance with specified procedures
   • Required maintenance documentation is 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, including the use of MSDS and PPE

using relevant maintenance documentation, specifications and aircraft/component manuals to:

recognise state of serviceability and repair requirements for the range of mechanical components listed in the Range of Conditions

fabricate components

identify requirements and complete repairs

test and/or adjust components, as required

correctly tagging, sealing and packaging completed components.

The underlying skills inherent in this unit should be transferable across a range of fabrication and repair applications associated with aircraft components. It is essential that the relevant procedures are interpreted and applied to ensure quality and safety standards are achieved. This shall be demonstrated through application across a number of different aircraft components listed in the Assessment Conditions.
