Elements and Performance Criteria

1. Remove avionic system components
   • System is rendered safe and prepared in accordance with the applicable maintenance manual and isolation tags are fitted where necessary to ensure personnel safety.
   • Avionic component removal is carried out in accordance with the applicable maintenance manual.
   • Required maintenance documentation is completed and processed in accordance with standard enterprise procedures.
   • Removed components are tagged and packaged in accordance with specified procedures.
2. Install avionic system components and verify system serviceability
   • Avionic components to be installed are checked to confirm correct part numbers, modification status, serviceability and shelf life.
   • Installation of avionic components is performed in accordance with the applicable maintenance manual and regulatory requirements.
   • System is reinstated to correct operational condition and is tested for serviceability.
   • Required maintenance documentation is completed and processed in accordance with standard enterprise procedures and regulatory requirements.

Required Skills

Required skills

Look for evidence that confirms skills in 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 selftest facility other onboard test systemsequipment or by simple ramp test equipment requiring a simple gono go decision 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 builtin test equipment to confirm system serviceability this may involve the operation of specific builtin test equipment onboard 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 builtin test equipment Onboard maintenance systems Integrated Modular Avionics and the interface with hydraulic fuel and pneumatic systems

Evidence Required

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 builtin test equipment or similar onboard systems andor offaircraft test equipment that provides a simple gono 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 generalpurpose tools test and ground support equipment found in most routine situations would be used where appropriate

Range Statement

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
