Elements and Performance Criteria

1. Interpret specifications and organise materials
   • Specifications are interpreted to determine the dimensions and procedure for fabrication
   • Appropriate materials, tools and equipment are selected and prepared for the particular specification requirements
2. Fabricate/repair electrical components or parts
   • Assembly or fabrication jigs, where applicable, are aligned to ensure accurate fabrication of components
   • 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 personal protective equipment (PPE)
3. Test fabricated/repaired components or parts
   • Test equipment and/or rigs are used, where applicable, to confirm serviceability of finished components
   • Fabricated components are tagged, sealed and packaged within specified 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 PPE and reference to MSDS

using approved repair/fabrication procedures and processes relating to electrical cables, harnesses, antenna leads and aerial components

recognising the integrity/security of electrical component crimps, wire wrapping, joints, and plug/connector pins

constructing cables, harnesses and looms, including wire marking, to approved industry standards

performing component testing to assess post-construction serviceability.

The underlying skills inherent in this unit should be transferable into other areas that require similar techniques. It is essential that the general aspects of material specification and selection, measurement and fabrication/manufacture are related to specific aircraft component applications.
