Elements and Performance Criteria

  1. Remove avionic system components
  2. Install avionic system components and verify system serviceability

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Procedures and requirements include:

Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise.

Avionic components include:

Components/line replaceable units (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

Tested for serviceability includes:

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

Performance Evidence

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.
