This unit of competency requires application of hand skills and the use of maintenance documentation/publications in the removal, installation and task certification of avionic system components of fixed and rotary wing aircraft during the performance of scheduled or unscheduled maintenance where system serviceability can be established by a simple self-test facility, other on-board test systems/equipment or by simple ramp test equipment. Maintenance may be performed individually or as part of a team.

The unit is part of the B1 maintenance certification licensing pathway under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.

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:

locating and identifying avionic components that are part of instrument and radio systems

determining that component and system serviceability can be confirmed by a simple self-test facility, other on-board test systems/equipment or by simple ramp test equipment requiring a simple go/no go decision

applying relevant WHS practices

applying component attachment methods

connecting hardware and plugs

handling precautions for electrostatic sensitive devices

using 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).

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 Assessment Conditions.

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:

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.

Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in maintenance manuals. It is also expected that applicable general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.

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.

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 avionic components, as listed in the Range of Conditions:

components/LRUs from electronic instrument systems

components/LRUs from engine indication systems

communication system components

navigation system components

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

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.
