Elements and Performance Criteria

1. Test synchro and servo system components
   • Synchro and servo system components are correctly prepared and connected to the appropriate test equipment/rig in accordance with approved procedures
   • Components are functionally tested or cycled through the prescribed test procedures in accordance with maintenance manual for evidence of serviceability or malfunction while observing all relevant work health and safety (WHS) requirements
   • Faults or unserviceabilities are correctly identified and recorded on appropriate maintenance documentation
2. Align synchro and servo system components
   • Synchro and servo system components are adjusted in accordance with approved procedures and maintenance manuals until operating within prescribed limits/tolerances
3. Troubleshoot synchro and servo system components
   • Available information from maintenance records and 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
   • Synchro and servo system component faults are located and the causes of the faults are clearly identified and correctly recorded in maintenance documentation, where required
   • Fault 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 repair procedures and processes relating to synchro and servo system components

recognising the serviceability state and repair requirements for:

synchro/servo system error detection devices

direct current (DC) and alternating current (AC) synchronous components

gyroscopic instruments (mechanical, electro-mechanical, vacuum/pressure types)

flight control servo devices

performing component testing to isolate/confirm faults and assessing post-repair/overhaul serviceability

correctly aligning synchro and servo system components to prescribed specifications

applying logic processes to isolate synchro and servo system component faults.

The underlying skills inherent in this unit should be transferable across a range of testing, aligning and troubleshooting applications (including the timely involvement of supervisors or other trades) associated with synchro and servo system components. Ability to interpret inspection and testing procedures and specifications (allowable limits) and apply them in practice is critical. It is essential that testing procedures, cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with.

This must be demonstrated through application across a range of the synchro and servo system components listed in the Assessment Conditions that are applicable to the enterprise.
