Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Instructions to Assessors

Evidence Guide

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

1.

Inspect electrical systems and components

1.1

Isolation tags are checked and aircraft configured for safe system inspection and operation in accordance with the applicable maintenance manual

1.2

Electrical system components and hardware are visually or physically checked for external signs of defects in accordance with applicable maintenance manual while observing all relevant work health and safety (WHS) requirements

1.3

Defects are correctly identified and recorded in accordance with standard enterprise procedures

Required Skills and Knowledge

Elements describe the essential outcomes.

Performance criteria describe the performance needed to demonstrate achievement of the element.

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 approved maintenance documentation and aircraft publications relating to the avionic system being maintained

recognition of system and electrical component defects/external damage, correct installation, connection of plugs, terminations, and attaching hardware (including cabling/harnesses) and security in:

AC and DC power generation systems, including regulation, distribution, control and cooling

battery installations and inverters

flight control and/or electro-hydraulic systems

engine ignition, starting, fuel distribution and control systems

internal/external lighting systems, including controls

doors

landing gear systems

anti-skid braking systems

master caution and warning systems

auxiliary systems (including ice/rain protection, fire detection, environmental control and pressurisation, waste and water, equipment and furnishings).

It is essential that inspection procedures, cleanliness requirements and safety precautions applicable to the electrical system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice (including the timely involvement of supervisors or other trades) is critical.

Evidence of transferability of skills and knowledge related to inspection is essential. This is to be demonstrated through application across a range of aircraft electrical systems, components and hardware listed in the Assessment Conditions.

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

component attachment methods and connection of hardware

explaining the basic layout (block diagram level) and operation of:

AC and DC power generation systems, including regulation, distribution, control and cooling

battery installations and inverters

flight control and/or electro-hydraulic systems

engine ignition, starting, fuel distribution and control systems

internal/external lighting systems, including controls

doors

landing gear systems

anti-skid braking systems

master caution and warning systems

auxiliary systems (including ice/rain protection, fire detection, environmental control and pressurisation, waste and water, equipment and furnishings)

WHS requirements applicable to the maintenance of aircraft electrical systems, including gas turbine engine high-energy ignition units

electrical system maintenance requirements

relevant maintenance manuals

relevant regulatory requirements and standard procedures.
