MEA387A
Test gas turbine engines and engine modules after overhaul or repair

Assessment tool

Version 1.0
Issue Date: May 2024


This unit requires application of hand skills, theory knowledge and maintenance publication procedures to test run aircraft gas turbine engines and engine modules in engine test stands following overhaul or repair in workshops.

Applications include turbo-jet, turbofan, turboshaft, turboprop engines and engine modules, or auxiliary power units.

This unit of competency is part of the Mechanical Certificate IV (Component Workshop Maintenance Stream) training pathway. It covers the competencies required to test run gas turbine engines or engine modules after overhaul or repair. This unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.

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 apply hand skills and gas turbine engine theory knowledge and use maintenance publications to test and adjust the operation of overhauled engines or modules 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 across a range of repair and/or overhaul applications associated with gas turbine engines and/or modules. It is essential that the maintenance procedures (including the use of correct fuels and lubricants) are interpreted and applied to ensure quality and safety standards are achieved.

Evidence of transferability of skills and knowledge related to repair is essential. This may be demonstrated through application across a number of gas turbine engine and/or module test runs. Capability to interpret test procedures and specifications (allowable limits) and apply them in practice is critical. The application of testing procedures should also clearly indicate knowledge of system operation. Knowledge of system operation and the relationship of individual components will be necessary to supplement evidence of ability to troubleshoot engine or module faults 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 engine/module test runs. 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 in an applicable engine test stand. 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:

applying relevant OHS procedures

using relevant MSDS and items of PPE

using relevant maintenance manuals and standard enterprise procedures to:

prepare engines or modules for test running

install engines in test stands

test run and trim engines where applicable

record engine operating parameters

remove engines from the test stand

complete documentation

configure and inhibit serviceable engines and modules for transport or storage

Required knowledge

Look for evidence that confirms knowledge of:

how to obtain relevant MSDS

the use of applicable items of PPE

test stand operation

engine and module test requirements

engine operating parameters and adjustment methods

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.

Engines

Engines include:

fixed or rotary wing gas turbine engine (turbo-jet, turbofan, turboshaft, turboprop), or auxiliary power unit

Modules

Modules may include:

various combinations of gas turbine engine sections as determined by the manufacturer

Application of this unit may relate to:

scheduled or unscheduled maintenance

individual or team-related activities

complex adjusting and testing of engine performance to be carried out under supervision

Procedures and requirements

Procedures and requirements refer to industry standard 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.
