Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Electrical hardware includes:

Switches, relays, lamps, terminal blocks, current limiters, circuit breakers, fuses, sockets, potentiometers, capacitors, inductors, magnetic amplifiers, transformers, rheostats, resistors and diodes, miscellaneous sensors and minor components hard mounted throughout the aircraft, busbars, lugs, ferrules, splices, connectors, and electrical, electronic cables and looms

Oxygen systems and components, and fuel tank components and integrated hardware are not included

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

using enterprise procedures, applicable maintenance documentation and aircraft publications relating to the electrical system and components being worked on

the preparation and termination of electrical cables to aircraft industry standards, using:

crimping techniques

soldering techniques

solder sleeve joints

the correct identification of aircraft wire markings, terminal block identification and plug/socket pin numbering systems

electrical loom and harness installation ensuring 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.

The underlying skills inherent in this unit should be transferable into other units that require similar techniques. It is essential that applicable cleanliness requirements and WHS safety precautions are fully observed, and an awareness of electrostatic discharge procedures.

Evidence of transferability of skills and knowledge related to enterprise procedures associated with removal and installation is essential.
