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, use maintenance publications and engine and system theory knowledge to inspect gas turbine engines and engine system components on fixed or rotary wing aircraft while applying all relevant safety precautions, in particular those relating to high-energy ignition units.

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 inspection applications (including the timely involvement of supervisors or other trades) associated with gas turbine engines, components and systems. It is essential that system test procedures take into account all safety precautions applicable to the system being maintained. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical.

Evidence of transferability of skills and knowledge related to inspection is essential. This may be demonstrated through application across a number of engine systems. 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 each of the systems listed in Range Statement Groups 1 to 6 and at least one component of each system. 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 and used to assist in the inspection process 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 and aircraft manuals to:

recognise through visual/physical inspection external and internal signs of defects/damage to gas turbine engine, components and system components

assist with testing of gas turbine engine and engine system operation

Required knowledge

Look for evidence that confirms knowledge of gas turbine engine and engine system layout and operation, including electrical and instrument system interfaces

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.

Gas turbine engine and components

Gas turbine engine may include:

1. Engine change unit, main components, accessories/drives

2. Control system

3. Ignition, starter systems

4. Fuel system

5. Oil system

6. Air system

Application of this unit may relate to:

Scheduled or unscheduled maintenance activities

Individual or team related activities

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.

Observation Checklist

Tasks to be observed according to workplace/college/TAFE policy and procedures, relevant legislation and Codes of Practice Yes No Comments/feedback
Isolation tags already attached to the system or related systems are checked and aircraft configured for safe system inspection and operation in accordance with applicable maintenance manual 
Gas turbine engine and/or components are visually or physically checked for external signs of defects in accordance with applicable maintenance manual.
