This unit of competency is applied in conjunction with units relating to the inspection, testing and troubleshooting of piston engines and gas turbine engines (either installed in aircraft or in workshops), to perform and assess the results of remote visual inspections using borescopes.

The unit is required for the grant of approval for Aircraft Maintenance Engineers to perform borescope inspections on aircraft system components and engines during scheduled or unscheduled maintenance.

The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian defence Force (ADF) and the Civil Aviation Safety Authority (CASA).

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

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.

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.

This shall be demonstrated through application across a representative range of borescope inspection tasks that are performed within the enterprise. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical.

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include 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.

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.

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.

The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.

A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on a representative range of the borescope inspection tasks performed within the enterprise.

This shall be established via the records in the Log of Industrial Experience and Achievement, or where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).

Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).

Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.

Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
