Elements and Performance Criteria

1. Inspect fixed wing single axis autopilot systems and components
   • Relevant maintenance documentation and modification status, including system defect reports, where relevant, are used to identify specific inspection requirements
   • Isolation tags are checked and aircraft configured for safe system inspection and operation in accordance with the applicable maintenance manual while observing all relevant work health and safety (WHS) requirements
   • Single axis autopilot system and components are visually or physically checked for external signs of defects in accordance with applicable maintenance manual
   • Defects are correctly identified and reported
2. Test/adjust fixed wing single axis autopilot systems and components
   • Aircraft and system are prepared in accordance with applicable maintenance manual for the application of power/system operation
   • Autopilot systems are functionally tested in accordance with maintenance manual for evidence of serviceability or malfunction
   • System calibration or adjustments are performed in accordance with maintenance manual, as appropriate
3. Troubleshoot fixed wing single axis autopilot systems
   • Available information from maintenance documentation, inspection and test results is used, where necessary, to assist in fault determination
   • Maintenance manual fault diagnosis guides and logic processes are used to ensure efficient and accurate troubleshooting
   • Specialist advice is obtained, where required, to assist with the troubleshooting process, using fault-finding charts or similar, to line replacement level
   • Autopilot 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
   • Rectification requirements are determined

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:

applying relevant WHS practices

using approved maintenance documentation and aircraft publications relating to the single axis autopilot system being maintained

recognising system and component defects/external damage, correct installation, connection of plugs, terminations, attaching hardware (including cabling/harnesses) and security in:

autopilot system components

radio navigation system interfaces

applying logic processes, taking and interpreting system measurements, and using test equipment and appropriate wiring diagrams and manuals, to accurately and effectively isolate system malfunctions

testing the system to isolate system malfunctions and assess post-maintenance serviceability.

It is essential that system testing procedures, cleanliness requirements and safety precautions applicable to the autopilot system being maintained are fully observed, understood and complied with. Ability to interpret inspection procedures and specifications (allowable limits) and apply them in practice across a range of inspection, testing and troubleshooting applications (including the timely involvement of supervisors or other trades) 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 an autopilot system and its components.
