Application
This unit of competency requires application of hand skills and the use of relevant maintenance publications to maintain and repair a range of aircraft mechanical components during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.
Applications include fixed and rotary wing aircraft classified by the Civil Aviation Safety Authority (CASA) as small aircraft and components in workshops.
The unit is part of the Mechanical Certificate IV (Aircraft Maintenance Stream) training pathway.
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.
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. | ||
1. | Maintain and/or repair mechanical components or parts | 1.1 | Maintenance and/or repair requirements are determined, following disassembly and assessment of component parts for serviceability, in accordance with the relevant maintenance documentation |
1.2 | Tagging and repair instructions are accurately specified for parts requiring specialist repair | ||
1.3 | Appropriate materials, tools, equipment and assembly or fabrication jigs are selected and prepared for the particular specification requirements | ||
1.4 | Components or parts are maintained, repaired or modified as approved by relevant manufacturers’ bulletins or procedures in accordance with required specifications | ||
1.5 | Mechanical component parts are assembled within specified tolerances and in accordance with the appropriate maintenance documents while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE) | ||
1.6 | Mechanical components are adjusted, as required, to operate within prescribed specifications | ||
1.7 | Test equipment and rigs are used, where applicable, to confirm serviceability | ||
1.8 | Maintained/repaired or modified components are tagged, sealed and packaged within specified procedures | ||
1.9 | Required maintenance documentation is completed and processed in accordance with standard enterprise procedures | ||
Evidence of Performance
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 include:
applying relevant WHS practices including the selection and use of PPE and MSDS
using relevant maintenance documentation, specifications and aircraft/component manuals to:
recognise state of serviceability and repair requirements for the range of components listed in the Range of Conditions that are applicable to the enterprise
identify requirements and complete repairs and/or modifications
test and/or adjust components as required
correctly tagging, sealing and packaging completed components that are not being immediately refitted.
The underlying skills inherent in this unit should be transferable across a range of maintenance and repair applications associated with aircraft components. It is essential that the relevant procedures are interpreted and applied to ensure quality and safety standards are achieved.
This shall be demonstrated through application across a number of different aircraft components.
Evidence of Knowledge
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:
mechanical component operation and repair procedures and processes:
hoses
pipes
cables, turnbuckles and tensioning devices
pulleys
chains and sprockets
gear drives
screwjacks
control rods
bellcranks
links
internal fittings and emergency equipment operation, construction, installation and maintenance/repair:
trim panels
linings and coverings
seats and crew/passenger restraints
cargo restraints
cabin equipment and consoles
emergency equipment inspection and stowage requirements:
passenger escape systems
life jackets
rafts
emergency location transmitters
applicable WHS procedures, including the selection and use of items of PPE
how to obtain relevant MSDS
how to identify suitable adhesives and patching materials for upholstery and trim
inspection and test requirements for restraint system components
safe stowage requirements for items of emergency equipment
how to determine serviceability of items of emergency equipment
relevant maintenance manuals, standards and specifications
relevant regulatory requirements and standard procedures.
Assessment Conditions
Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance documentation. It is also expected that applicable general and special-purpose tools and test equipment found in most routine situations would be used where appropriate.
Ability to assess component serviceability and interpret parts requirements will be necessary before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.
The following conditions of assessment represent the requirements of the Regulators (ADF and CASA) and maintenance stakeholders and must be rigorously observed.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on the components or parts that are applicable to the enterprise, from each of the following groups:
hoses
pipes
cables, pulleys, chains, sprockets and gear drives
control rods, bellcranks, links and screwjacks
trim panels; linings; seats; cabin equipment and consoles; coverings; and emergency equipment stowage, including passenger escape systems, life jackets, rafts, location transmitters, cargo, crew and/or passenger seat restraints).
This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
