Required Skills
Required skills |
Look for evidence that confirms skills in: using hand skills and tools to remove and install hydraulic and fuel system components jacking of the aircraft, as required, for landing gear component removal and installation correctly installing and securing of aircraft hardware using hand skills and tools to remove and install landing gear components and the correct handling of heavy components using maintenance manuals to prepare the aircraft for component removal and installation and correct interpretation of removal and installation instructions applying standard procedures observing all relevant OHS procedures, including the use of MSDS and relevant items of PPE |
Required knowledge |
Look for evidence that confirms knowledge of: standard trade practices relating to tool usage and installation/securing of aircraft hardware hydraulic fluids (mineral and synthetic) and handling precautions hydraulic seal types and applications how to locate and correctly remove and install components of hydraulic systems aircraft fuels and handling precautions fuel seal types and applications how to locate and correctly remove and install fuel system components electrical circuit isolation and plug removal and installation how to jack the aircraft for landing gear component removal and installation how to locate and correctly remove and install landing gear components, including the handling of heavy components OHS procedures relating to hydraulic systems, fuel systems and landing gear components how to obtain MSDS the selection and use of items of PPE relevant maintenance manuals relevant regulatory requirements and standard procedures |
Evidence Required
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 remove and install a range of hydraulic and fuel system and landing gear components in accordance with relevant maintenance manual instructions while applying all relevant OHS procedures and standard processes. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit | The underlying skills inherent in this unit should be transferable into other units that require similar techniques. It is essential that system cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with. Evidence of transferability of skills and knowledge related to removal and installation is essential. This may be demonstrated through application across a number of aircraft systems or aircraft types, but must cover a sufficient range of tasks to demonstrate familiarity with attachment methods, connection hardware and couplings peculiar to each type of system, and of safe handling of heavy components. An understanding of system operation as it relates to the work must be demonstrated 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 this unit of competency are being achieved under routine supervision on each type of system and on at least one component of each Group listed in the Range Statement, as follows: Hydraulic systems - preparation of a system for safe component removal and replacement of at least one component from each of hydro-mechanical system components 3 and 5 Fuel systems - preparation of a system for safe component removal and replacement of at least one component from each of 4 and 5 Landing gear components - one each of 6 to 8. Coverage of brakes and struts/oleos are not required where the aircraft is rotary wing and is fitted with skids or floats. 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 work environment or simulated work environment, using procedures, tools and equipment specified in maintenance documentation. It is also expected that general purpose tools, test and ground support equipment found in most routine situations would be used where appropriate. |
