1. Interpret specifications and organise materials

1.1. Specifications are interpreted to determine the dimensions and procedure for fabrication

1.2. Appropriate materials, tools and equipment are selected and prepared for the particular specification requirements

2. Fabricate/repair electrical components or parts

2.1. Assembly or fabrication jigs, where applicable, are aligned to ensure accurate fabrication of components

2.2. Components or parts are fabricated in accordance with required specifications

3. Test fabricated/repaired components or parts

3.1. Test equipment and rigs are used, where applicable, to confirm serviceability of finished components

3.2. Fabricated components are tagged, sealed and packaged within specified procedures

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 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.

Method of assessment
