Fabricate and_or repair aircraft electrical hardware or parts

Assessment tool

Version 1.0
Issue Date: May 2024


This unit requires application of hand skills and knowledge of wiring standards and specifications to fabricate aircraft electrical looms, harnesses and cables.

Applications include aircraft maintenance hangars and workshops.

This unit of competency is part of all Avionic Certificate IV training pathways. It is also part of the Mechanical Aircraft Maintenance Engineer licensing pathway. It covers the competencies required to fabricate and repair aircraft electrical hardware or parts. The unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.

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.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

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 fabricate aircraft electrical looms, cables and harnesses in accordance with applicable standards and specifications while observing all relevant safety precautions.

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

The underlying skills inherent in this unit should be transferable into other areas that require similar techniques. It is essential that the general aspects of material specification and selection, measurement and fabrication/manufacture are related to specific aircraft component applications.

Evidence of knowledge about individual components and their links with systems will be necessary to supplement evidence of ability to interpret requirements and fabricate components 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 a representative range of tasks from Groups 1 to 4 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 work environment or simulated work environment using tools and equipment specified by aircraft in the maintenance manuals. It is also expected that general purpose tools and test 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:

applying relevant OHS practices, including the use of PPE and reference to MSDS

using approved repair/fabrication procedures and processes relating to electrical cables, harnesses, antenna leads and aerial components

recognising the integrity/security of electrical component crimps, wire wrapping, joints and plug/connector pins

constructing cables, harnesses and looms, including wire marking, to approved industry standards

performing component testing to assess post construction serviceability

Required knowledge

Look for evidence that confirms knowledge of:

component and system operation

aircraft wiring specifications and standards

standard repair methods for:

electrical cables

ignition harnesses

fire warning system harnesses

coaxial cables, such as antenna leads

aerial components

electrical plugs and connectors

soldering methods

fabrication methods for the above wiring and cables

wire marking methods

assembly of electrical cables into wiring looms

relevant OHS procedures

how to obtain relevant MSDS

relevant maintenance manuals

relevant regulatory requirements and standard procedures

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

Components or parts

Components or parts may include electrical looms, harnesses and cables associated with:

1. Power distribution

2. Ignition

3. Control circuits

4. Signal circuits

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.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
