Required Skills and Knowledge

Required skills 

Look for evidence that confirms skills in:

  • applying relevant OHS practices, including the use of MSDS and PPE
  • using approved maintenance documentation and aircraft publications relating to aircraft seat and pod electrical and electronic systems and components
  • recognising defects in and deterioration of electrical cables to aircraft industry standards, including crimped and soldered joints
  • correctly interpreting aircraft wire markings, terminal block identification and plug/socket pin numbering systems
  • inspecting 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
  • positively identifying seat and pod electrical and electronic system components

Evidence Guide

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria, required skills and knowledge, range statement and the Assessment Guidelines for the Training Package.

Overview of assessment 

A person who demonstrates competency in this unit must be able to apply hand skills, use specialist tools and use maintenance publications to remove and install seat and pod electrical and electronic system components, and to functionally test the systems while observing all relevant safety precautions.

Critical aspects for assessment and evidence required to demonstrate competency in this unit 

It is essential that applicable cleanliness requirements and OHS 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. 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.

A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the unit of competency are being achieved on the range of components and tasks listed in the Range Statement. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.

Context of and specific resources for assessment 

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 situations would be used where appropriate.

Method of assessment
