Description
This unit of competency is part of the Avionic Certificate IV (Aviation Maintenance Stream) training pathway. It covers the competencies required to inspect, test and troubleshoot instrument systems and components fitted to the more advanced types of fixed and rotary wing aircraft. The unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA. Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen Aircraft Maintenance Engineer Licence under CASR Part 66, in accordance with the licensing provisions in Section 3, Assessment Guidelines.
Notes
Elements and Performance Criteria
1. Inspect aircraft advanced instrument systems and components
- 1.1. Relevant maintenance documentation and modification status, including system defect reports, where relevant, are used to identify specific inspection requirements
- 1.2. Isolation tags are checked and aircraft configured for safe system inspection and operation in accordance with the applicable maintenance manual
- 1.3. Instrument system components are visually or physically checked for external signs of defects in accordance with applicable maintenance manual
- 1.4. Defects are correctly identified and reported
2. Test/adjust aircraft advanced instrument systems and components
- 2.1. Aircraft and system are prepared in accordance with applicable maintenance manual for the application of power/system operation
- 2.2. Instrument system is functionally tested, in accordance with maintenance manual, for evidence of serviceability or malfunction
- 2.3. System calibration or adjustments are performed in accordance with maintenance manual, as appropriate
3. Troubleshoot aircraft advanced instrument systems
- 3.1. Available information from maintenance documentation, inspection and test results is used, where necessary, to assist in fault determination
- 3.2. Maintenance manual fault diagnosis guides and logic processes are used to ensure efficient and accurate troubleshooting
- 3.3. Specialist advice is obtained, where required, to assist with the troubleshooting process
- 3.4. Instrument system faults are located and the causes of the faults are clearly identified and correctly recorded in maintenance documentation, where required, in accordance with standard enterprise procedures
- 3.5. Rectification requirements are determined
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.

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 inspect, test and troubleshoot advanced instrument systems and components while observing all relevant safety precautions.
Critical aspects for assessment and evidence required to demonstrate competency in this unit
The underlying skills inherent in this unit should be transferable across a range of inspection, testing and troubleshooting applications (including the timely involvement of supervisors or other trades) associated with aircraft advanced instrument systems and components. It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical.
Evidence of transferability of skills and knowledge related to inspection, testing and troubleshooting is essential. This is to be demonstrated through application across a range of advanced aircraft instrument systems and components listed in the Range Statement. The application of testing procedures should clearly indicate knowledge of system operation, the relationship of individual components and the links with other systems (if applicable) within the limits of the aircraft/system fault finding guide 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 system and at least one major system component/(LRU from each of Groups 1 to 7 (Groups 6 and 7 may be omitted where they are not applicable to the enterprise) 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 Evidence Guide.
Context of and specific resources for assessment
Competency should be assessed in the workplace or simulated workplace using tools and equipment specified in the maintenance manuals. It is also expected that general and special purpose tools, test and ground support equipment would be used where appropriate.
Method of assessment
Guidance information for assessment
Individuals being assessed who have already attained MEA212C Inspect, test and troubleshoot basic aircraft instrument systems and components, will have covered inspection, testing and troubleshooting of a range of flight instruments and direct reading compass and measuring systems. Log of Industrial Experience and Achievement records relating to MEA212C Inspect, test and troubleshoot basic aircraft instrument systems and components, may be accepted as also meeting the evidence requirements for this unit in the applicable areas.
Advice provided in MEA212C Inspect, test and troubleshoot basic aircraft instrument systems and components, regarding MEA275A Maintain basic light aircraft instrument systems and components, should also be considered where applicable.
