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 MSDS

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

plug connector pin removal and insertion where soldering is not required

recognising damage and visual defects in electrical components, such as actuators, motors and switches

recognising damage and visual defects in electronic system components, such as display screens, tuners, volume controls, audio headset receptacles and data cables.

It is essential that applicable cleanliness requirements and WHS precautions are fully observed, including awareness of electrostatic discharge procedures.

Evidence of transferability of skills and knowledge related to removal and installation is essential.
