MEA239B
Fabricate aircraft electrical looms and harnesses

Assessment tool

Version 1.0
Issue Date: May 2024


This unit requires application of hand skills and maintenance publications to fabricate aircraft electrical looms and harnesses under qualified person guidance for general use in electrical systems.

Applications include aircraft hangars and workshops.

This unit is part of the Avionic Certificate II training pathway. It covers the competencies required to fabricate and test, under qualified person guidance, a range of aircraft electrical looms and harnesses. No licensing requirements apply to this unit at the time of publication.

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, harnesses and cables for general electrical system use 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 be related to specific aircraft component applications to the extent necessary to unambiguously understand expert guidance.

Evidence of knowledge about individual components and their links with systems will be necessary to supplement evidence of ability to interpret qualified person guidance and enterprise procedures to fabricate looms, harnesses and cables before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

Safety precautions applicable to the manufacturing of electrical looms, harnesses and cables are to be fully observed. An understanding of system operation as it relates to the work must be demonstrated before undertaking any action, to ensure safety and quality issues are addressed.

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 qualified person guidance on a representative range of electrical loom, cable and harness fabrication tasks as provided for 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 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:

application of relevant OH&S practices

the use of approved fabrication procedures and processes relating to electrical looms, cables, and harnesses

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

fabrication of cables, harnesses and looms, including wire marking, to approved industry standards.

under qualified person guidance performing testing to assess post construction serviceability according to enterprise procedures

Required knowledge

Look for evidence that confirms knowledge of:

electrical wire gauges and standards

wire marking conventions and procedures

wire terminations, soldering and crimping

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.

Application of this unit may relate to:

Application of this unit may relate to:

routine scheduled or unscheduled maintenance activities performed under qualified person guidance in accordance with enterprise procedures and applicable maintenance documentation

work undertaken either autonomously or as part of a team and under the guidance of a qualified person. Routine work is carried out using basic operational knowledge and a defined range of skills ('routine' work is that which follows a customary or regular course of procedure). All work outcomes are achieved by applying known solutions chosen from a limited range of pre-determined options consistent with enterprise procedures. This includes accepting responsibility for own work in terms of quality of outcomes using pre-determined specifications of quality.

Note that the scope of any fabrication and the procedure to be followed will be provided by the qualified person, and be within the scope of the skills and knowledge included in Unit MEA1O9A.

Components or parts

Components or parts include:

Electrical looms, harnesses and cables except for:

data bus cables

co-axial cables

fibre optic cables

fire detection/extinguishing systems

oxygen systems

fuel tanks and integrated hardware

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
