Application of relevant occupational health and safety (OHS) practices

Component attachment methods

Connection of hardware and plugs

Handling precautions for electrostatic sensitive devices

The use of approved maintenance documentation and aircraft publications relating to avionic systems

Using built-in test equipment to confirm system serviceability (this may involve the operation of specific built-in test equipment, on-board maintenance systems and Integrated Modular Avionic modules)

Required knowledge

Look for evidence that confirms knowledge of:

Electronic fundamentals

Digital techniques relating to electronic instrument systems

Engine indication systems

The operation of built-in test equipment

On-board maintenance systems

Integrated Modular Avionics and the interface with hydraulic, fuel and pneumatic systems

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 remove and install avionic components and verify system serviceability through the use of built-in test equipment or similar on-board systems and/or off-aircraft test equipment that provides a simple go/no go decision while observing all relevant safety and component handling precautions.

Critical aspects for assessment and evidence required to demonstrate competency in this unit

It is essential that cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with, as well as work practices associated with electrostatic sensitive devices.

Evidence of transferability of skills and knowledge related to removal and installation is essential. This is to be demonstrated by application across a range of aircraft avionic system components as listed in the Range Statement. An understanding of the attachment methods, connection of hardware, and system test requirements as they relate to the work must be demonstrated 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 avionic components, as 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 workplace or simulated workplace 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 would be used where appropriate.

Method of assessment

Guidance information for assessment

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

The scope of this Unit is restricted to removing and installing avionic components from systems whose serviceability can be established and certified through the use of built-in test equipment or any other on-board system that can verify correct system operation. The use of off-aircraft test equipment is limited to items that provide a simple go/no go decision.

Application of this unit may relate to:

scheduled or unscheduled maintenance

individual or team related activities

Procedures and requirements

Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise.

Avionic components

Avionic components include:

components/line replaceable units from electronic instrument systems

components/line replaceable units from engine indication systems

communication system components

navigation system components

software updates to avionic systems where serviceability can be determined by a simple test

Tested for serviceability

Tested for serviceability means:

confirming system serviceability through the operation of built-in test equipment or any other on-board system that can confirm correct operation

using only off-aircraft test equipment that provides a simple go/no go decision regarding system serviceability
