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 apply borescope inspection techniques to inspect piston or gas turbine engine internal components on fixed or rotary wing aircraft or in workshops 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 remote visual inspection applications associated with internal engine components. It is essential that inspection procedures take into account all safety precautions associated with borescope inspection techniques and the applicable engine.

Evidence of transferability of skills and knowledge related to borescope inspection and assessment of results is essential. This may be demonstrated through application across a number of engine types. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical.

Demonstrated knowledge of both borescope inspection techniques and of the subject engine 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 Ccompetency are being achieved under routine supervision on representative range of borescope inspection tasks. 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 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:

selecting applicable borescope equipment and assembling it for use

identifying required borescope inspections and required techniques using applicable maintenance data

setting up the applicable system component or engine in accordance with applicable maintenance data for safe borescope inspection

applying borescope inspection techniques to safely perform required inspections without damage to engine components

identifying and correctly assessing and reporting/recording defect indications

maintaining and correctly storing borescope equipment after use

Required knowledge

Look for evidence that confirms knowledge of:

types of borescope and their applications

how to assemble borescope equipment and prepare it for use

use of associated imaging and recording equipment, such as video and digital camera

use of maintenance data to identify borescope inspection requirements

borescope inspection techniques and safety

remote engine rotation equipment

defect assessment techniques

borescope inspection reporting and recording requirements

borescope maintenance and storage requirements

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

Borescope equipment

Borescope equipment may include:

rigid optical borescopes

flexible optical borescopes

video borescopes

camera attachments for optical borescopes

remote engine rotation equipment

Applicable maintenance data

Applicable maintenance data may include:
