Application
This unit of competency requires application of skills in basic soldering and in crimping associated with the removal and installation of miscellaneous electrical hardware and components fitted to fixed or rotary wing aircraft during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
The unit is part of all Avionic Certificate IV training pathways and is also part of the Mechanical Aircraft Maintenance Engineer licensing 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).
Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.

1.3 | Required maintenance documentation is completed and processed in accordance with standard enterprise procedures | |||
1.4 | Removed components are tagged, packaged or discarded in accordance with specified procedures | |||
2. | Install aircraft electrical hardware | 2.1 | Electrical hardware components to be installed are checked to confirm correct part numbers, modification status, serviceability and shelf life | |
2.2 | Physical installation of electrical hardware is carried out in accordance with the applicable maintenance manual | |||
2.3 | System is reinstated to correct physical condition in preparation for testing, as necessary | |||
2.4 | Required maintenance documentation is completed and processed in accordance with standard enterprise procedures | |||
Evidence of Performance
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:
the preparation and termination of electrical cables to aircraft industry standards, using crimping techniques, soldering techniques and solder sleeves joints
the correct interpretation of aircraft wire markings, terminal block identification and plug/socket pin numbering systems
inspection of electrical looms and harness pre and post-removal and installation to ensure minimum bends are maintained, cable is not in tension, plugs are correctly aligned, security of route ensures no chaffing of insulation, adequate clipping and cable ties have been utilised and construction complies with aircraft industry standards
positive identification of miscellaneous electrical hardware and/or components in all aircraft systems.
Evidence of Knowledge
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:
component attachment methods
connection of hardware and plugs
application of relevant WHS practices
the use of approved maintenance documentation and aircraft publications relating to miscellaneous aircraft electrical hardware and components
electrical wiring used in aircraft and wire marking
plug/socket pin numbering and terminal block identification
cable and loom installation requirements
crimping tools and crimp terminals
soldering techniques and the use of solder sleeve joints
electrical fundamentals.
Assessment Conditions
Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine maintenance situations would be used where appropriate.
An understanding of the attachment methods, connection of hardware and system operation as they relate to the work must be demonstrated before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.
It is essential that applicable cleanliness requirements and WHS safety precautions are fully observed, including awareness of electrostatic discharge procedures.
Evidence of transferability of skills and knowledge related to removal and installation is essential.
The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria are being achieved under routine supervision on each of the connection methods:
bolted
soldered
plug connectors.
This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Implementation Guide).
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
