Elements and Performance Criteria

1. Maintain and/or repair mechanical components or parts
   • Maintenance and/or repair requirements are determined, following disassembly and assessment of component parts for serviceability, in accordance with the relevant maintenance documentation
   • Tagging and repair instructions are accurately specified for parts requiring specialist repair
   • Appropriate materials, tools, equipment and assembly or fabrication jigs are selected and prepared for the particular specification requirements
   • Components or parts are maintained, repaired or modified, as approved by relevant manufacturers’ bulletins or procedures, in accordance with required specifications 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)
   • Mechanical component parts are assembled within specified tolerances and in accordance with the appropriate maintenance documents
   • Mechanical components are adjusted, as required, to operate within prescribed specifications
   • Test equipment and rigs are used, where applicable, to confirm serviceability
   • Maintained/repaired or modified components are tagged, sealed and packaged within specified procedures
   • Required maintenance documentation is completed and processed in accordance with standard enterprise procedures

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Components or parts to be maintained and/or repaired include:	Hoses Pipes Cables, pulleys, chains, sprockets and gear drives Control rods, bellcranks and links Non-structural removable components of fuselages, fairings, nacelles, empennage, wings and thrust reversers. for non-pressurised aircraft – entry, cargo, access doors and associated seals, windows and transparent panels Trim panels, linings, seats, cabin equipment and consoles, floor panels, coverings and emergency equipment (including passenger escape systems, inflatable slides, life jackets, rafts, location transmitters, beacons, and cargo, crew and/or passenger seat restraints)
Repair includes:	Standard techniques for pipes and replacement of eye-ends, tubes or bearings for control rods/pulleys/sprockets and bushes or bearings for bellcranks and links
Maintain involves:	Cleaning, inspection for wear or damage, and adjustment and lubrication, where applicable
Procedures and requirements include:	Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

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, including the use of MSDS and PPE

using relevant maintenance documentation, specifications and aircraft/component manuals to:

recognise state of serviceability and repair requirements for the range of mechanical components listed in the Range of Conditions

identify requirements and complete repairs and/or modifications

test and/or adjust components, as required.

correctly tag, seal and package completed components

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 as listed in the Assessment Conditions.
