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

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 and use maintenance publications to remove and install aircraft pneumatic system components while applying 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 units that require similar techniques. It is essential that system cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with.

Evidence of transferability of skills and knowledge related to removal and installation is essential. This may be demonstrated through application across a number of aircraft systems or aircraft types, but must cover a sufficient range of tasks to demonstrate familiarity with attachment methods, connection hardware and couplings peculiar to each type of system, and of safe handling of heavy components. An understanding of system operation as it relates 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 one item from each of Groups 1 to 6 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 or simulated work environment 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.

Method of assessment

Guidance information for assessment

Required Skills and Knowledge

Required skills

Look for evidence that confirms skills in:

Application of relevant occupational health and safety (OHS) practices including the use of Material Safety Data Sheets (MSDS) and personal protective equipment (PPE)

The use of relevant maintenance documentation and aircraft manuals to:

Locate and correctly remove and install components in pneumatic systems, including fire-extinguishing systems

Locate and correctly remove and install components in air cycle air conditioning systems

Locate and correctly remove and install components in pressurisation systems

Correctly remove and install rigid and flexible pipelines

Correctly remove and install ducting

Required knowledge

Look for evidence that confirms knowledge of:

Component attachment methods

Connection hardware and couplings

Standard trade practices relating to tool usage and installation/securing of aircraft hardware

How to locate and correctly remove and install components of:

pneumatic systems

air cycle air conditioning system components

pressurisation system components

fire extinguishers including the ozone-depleting properties of halons and special precautions and handling requirements for BCF fire extinguishers

Electrical circuit isolation and plug removal and installation

OHS procedures relating to pneumatic, air conditioning and pressurisation systems

How to obtain MSDS

The selection and use of items of PPE

Relevant maintenance manuals

Relevant regulatory requirements and standard procedures including those relating to the handling and control of halon fire extinguishers

Range Statement

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.
