Description
This unit of competency requires application of hand skills, standard trade practices, and systems knowledge in the testing and troubleshooting of aircraft hydro-mechanical, mechanical, gaseous and landing gear systems and components of fixed wing aircraft during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.The unit is part of the Mechanical Aircraft Maintenance Engineer (AME) Certificate IV (Aircraft Maintenance Stream) training pathways and must be taken with MEA318 Inspect aircraft hydro-mechanical, mechanical, gaseous and landing gear systems and components.The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation safety Authority (CASA). Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.
Notes
Elements and Performance Criteria
1. Prepare for troubleshooting
  • 1.1 Relevant maintenance documentation and modification status, including system defect/service difficulty reports, where relevant, are interpreted to identify an unserviceability
2. Test hydro-mechanical, mechanical, gaseous and landing gear systems and components
  • 2.1 The aircraft and hydro-mechanical, mechanical, gaseous and landing gear systems are correctly prepared in accordance with specified procedures for the application of power
  • 2.2 Power is applied and system and components functionally tested in accordance with specified procedures for evidence of malfunction or leaks while applying all relevant work health and safety (WHS) procedures
  • 2.3 System calibration or adjustments are performed in accordance with specified procedures
3. Troubleshoot hydro-mechanical, mechanical, gaseous and landing gear systems and components
  • 3.1 Available information from maintenance documentation and inspection and test results is used, where necessary, to assist in fault determination
  • 3.2 Maintenance manual fault diagnosis guide and logical processes are used to ensure efficient and accurate troubleshooting to line replacement level
  • 3.3 Specialist advice is obtained, where required, to assist with the troubleshooting process
  • 3.4 Hydro-mechanical, mechanical, gaseous and landing gear system and component faults are located and the causes of the faults are clearly identified and correctly recorded in maintenance documentation, where required
  • 3.5 Fault rectification requirements are determined to assist in planning the repair or adjustment
