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 dismantle, inspect, maintain and assemble aircraft gas turbine engine components or parts under qualified person guidance 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 across a range of maintenance and repair applications associated with engine components. It is essential that the relevant enterprise procedures are interpreted and applied to ensure quality and safety standards are achieved.

Evidence of transferability of skills and knowledge related to enterprise procedures for maintenance and repair is essential. This may be demonstrated through application across a number of different engine components. Ability to assess component serviceability under qualified person guidance and interpret parts requirements will be necessary 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 qualified person guidance on a representative range of components or parts listed 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 documentation. It is also expected that general and special purpose tools 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 procedures

the use of relevant maintenance documentation, specifications and aircraft/component manuals to:

recognise state of serviceability and standard/routine maintenance and repair requirements for the range of engine components listed in the Range Statement

identify requirements under the guidance of a qualified person and complete repairs and/or modifications

Correctly tag, seal and package completed components

Required knowledge

Look for evidence that confirms knowledge of:

component operation at a basic level

standard/routine repair procedures and processes

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.

Routine work

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).

Work outcomes

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.

Components

Maintain basic components such as oil coolers, fuel nozzles, flex drive shafts, fuel manifolds and engine bearings. Also, engine change unit hoses, pipes and ducts, and like components fitted to modular assemblies and sub-assemblies

Repair or modify

Repair or modify compressor and turbine blades

Scope of work

Note that the scope of any repair or modification 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 the Unit of Competency MEA109B .

Maintain

Maintain involves removal and installation, cleaning, inspection for wear or damage and consequent replacement of parts, and routine adjustment and lubrication where applicable in accordance with enterprise procedures.

Work can relate to:

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

tasks performed either autonomously or as part of a team and under the guidance of a qualified person

Procedures and requirements

Refer to 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.
