Remove and install miscellaneous aircraft electrical hardware_components

Assessment tool

Version 1.0
Issue Date: May 2024


This unit requires application of skills in basic soldering and in crimping associated with the removal and installation of electrical hardware.

Applications include miscellaneous electrical hardware fitted to fixed or rotary wing aircraft.

This unit of competency is part of all Avionic Certificate IV training pathways and is also part of the Mechanical Aircraft Maintenance Engineer licensing pathway. It covers the competencies required for the removal and installation of miscellaneous electrical hardware and components found in various systems of both fixed and rotary wing aircraft. Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen Aircraft Maintenance Engineer Licence under CASR Part 66, in accordance with the licensing provisions in Section 3, Assessment Guidelines.

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 miscellaneous items of aircraft electrical hardware/components 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 under routine supervision on each of the connection methods 1, 2 and 3 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.

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Look for evidence that confirms skills in:

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

Required knowledge

Look for evidence that confirms knowledge of:

component attachment methods

connection of hardware and plugs

application of relevant OHS 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 and related mathematical and physics principles

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Note

Range statements listed below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide

Hardware connection methods

Removal and installation of electrical hardware involves one or more of the following connection methods:

1. Bolted

2. Soldered

3. Plug connectors

Types of electrical hardware

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

Basic soldering and crimping

The work will include the application of basic soldering and crimping skills associated with removal and installation of electrical hardware

Application of this unit may relate to:

scheduled or unscheduled maintenance activities

individual or team-related activities

Procedures and requirements

Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
