Application
This unit of competency requires application of hand skills and the use of maintenance publications to repair fixed and rotary wing aircraft non-primary structure non-metallic components under the guidance of a qualified person.
This unit is part of the Aeroskills Structures Maintenance Certificate II training pathway.
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).
Elements and Performance Criteria
Elements describe the essential outcomes. | Performance criteria describe the performance needed to demonstrate achievement of the element. | ||
1. | Prepare to perform routine repairs and minor modifications to aircraft non-primary structural non-metallic components | 1.1 | Applicable non-metallic repair scheme is determined in accordance with applicable maintenance documentation, enterprise procedures and qualified person guidance |
1.2 | All required materials and equipment are selected and organised in accordance with enterprise procedures and maintenance documentation | ||
2. | Perform routine repairs and minor modifications to aircraft non-primary structural non-metallic components | 2.1 | Work is performed in accordance with approved repair scheme, ensuring that aircraft standard practices are used and standard process requirements are carried out 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) |
2.2 | Work area is cleaned of all waste material or adjustments | ||
2.3 | Under guidance of a qualified person, minor adjustments are made, where necessary, for components to operate within prescribed specifications | ||
3. | Complete routine repair and minor modification activities | 3.1 | Required documentation is accurately completed and correctly processed in accordance with enterprise procedures |
3.2 | Repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures, where required |
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 must include:
applying relevant WHS procedures, including the use of PPE and MSDS
using enterprise procedures, approved maintenance documentation and aircraft publications relating to aircraft non-primary structural non-metallic components
identifying various aircraft non-primary structural non-metallic components and their basic properties by interpretation of markings, numbering systems or visual, chemical or mechanical means
handling and storing aircraft non-metallic components, including sealing agents, to industry standards
identifying aircraft assembly fasteners by interpretation of markings, numbering systems, size, shape and colour
correctly interpreting, with expert guidance and in accordance with enterprise procedures, non-primary structural non-metallic repair scheme/modification drawings and hand sketches
using appropriate hand tools and machines under guidance of a qualified person to remove and assemble aircraft non-metallic components
performing under guidance and in accordance with enterprise procedures a range of routine non-primary structural non-metallic repair techniques
restoring sealing and surface finishes.
The underlying skills inherent in this unit should be transferable into other areas that require similar techniques. It is essential that procedures take into account all safety precautions and quality requirements, standards and practices, and processes associated with assembly.
Evidence of knowledge about enterprise procedures relating to routine basic repair techniques and the use of the standard repair manual/practices in a range of situations will be necessary to supplement evidence of ability to plan and undertake component repair under qualified person guidance.
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:
aircraft non-metallic component construction principles and repair techniques at a basic level
how to obtain relevant MSDS
the use of applicable items of PPE
WHS procedures.
Assessment Conditions
Competency should be assessed in the work environment, using tools and equipment specified by aircraft maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.
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 qualified person guidance on a representative range of components, including interior trim panels (sidewalls, galleys, toilets, roof panels, floor panels), cargo lining, fairings and windows using applicable materials from:
non-metallic materials including fibreglass, sandwich honeycomb, nylon, Perspex, nomex core materials, and matrix resins.
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).
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
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. | ||
Materials and components include: | Applicable non-metallic materials for the routine repair and/or minor modification under guidance of a qualified person to non-primary structural non-metallic components, as follows: non-metallic materials include fibreglass, sandwich honeycomb, nylon, Perspex, nomex core materials, and matrix resins components include interior trim panels (sidewalls, galleys, toilets, roof panels, floor panels), cargo lining, fairings and windows Note that ‘primary structure/structural’ refers to all components of an aircraft, the failure of which would seriously endanger safety, for example, wing or tailplane spars, main fuselage frames, engine bearers, portions of skin that are highly stressed. ‘Non-primary’ refers to any other items Note that the scope of any modification and the procedure to be followed will be provided by the qualified person | |
