Description
This unit is part of the Avionic AME Certificate IV training pathways and is an alternative unit to MEA231B. It covers the competencies required to test and troubleshoot automatic flight control systems and components of fixed wing aircraft. Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the B2 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. Prepare for troubleshooting.
- 1.1. Relevant maintenance documentation and modification status, including system defect reports where relevant, are used to identify an unserviceability.
2. Test/adjust automatic flight control system
- 2.1. Aircraft and system are prepared in accordance with applicable maintenance manual for the application of power/system operation.
- 2.2. Automatic flight control 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 automatic flight control system
- 3.1. Available information from maintenance documents and 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. Automatic flight control system faults are located and the causes of the faults are clearly identified and correctly recorded in maintenance documentation, where required.
- 3.5. Determine rectification requirements.
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
Range statements listed below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide.
Automatic flight control systems
Automatic flight control systems may include:
1. Automatic pilot
2. Flight director
3. Automatic trim
4. Yaw damper
5. Automatic throttle and automatic landing.
Troubleshooting
Troubleshooting involves the use of fault finding charts or similar, to line replacement level.
Application
Application of this unit may relate to:
Scheduled or unscheduled maintenance activities
Individual or team related activities
Procedures and requirements
Refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

EVIDENCE GUIDE
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 test and troubleshoot automatic flight control 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 testing and troubleshooting applications (including the timely involvement of supervisors or other trades) associated with fixed wing aircraft automatic flight control 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 testing and troubleshooting is essential. This is to be demonstrated through application across a range of aircraft automatic flight control 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 at least one item from each of Groups 1 to 4 listed in the Range Statement (Group 5 may be omitted where it is not applicable to the enterprise). 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 the maintenance manuals. It is also expected that general and special purpose tools, test and ground support equipment would be used where appropriate.
