| | 3.4 | Condition of needle is checked to ensure it is sharp, clean and free from rust and dirt |
| | 3.5 | Needle is fitted to machine |
| | 3.6 | Machine is threaded and thread is checked for free travel from spool |
| | 3.7 | Thread tension and other machine settings are checked and adjusted using test pieces if necessary |
4. | Operate machine | 4.1 | Work piece is correctly aligned to machine |
| | 4.2 | Machine is operated in accordance with standard procedures while observing all relevant work health and safety (WHS) requirements |
| | 4.3 | Work piece is appropriately fed into machine |
| | 4.4 | Performance of machine is monitored through regular checking of thread tension and other settings and inspection of stitching in finished product |
5. | Inspection, quality, labelling and documentation | 5.1 | Work piece is removed from machine using assistance if necessary |
| | 5.2 | Completed work is inspected to verify that it meets applicable technical instructions |
| | 5.3 | Any areas in need of rework or rectification are identified and marked |
| | 5.4 | Rework is performed or other appropriate action arranged |
| | 5.5 | Completed product is labelled or tagged and any necessary documentation completed in accordance with standard enterprise procedures |
6. | Clean up and maintain equipment | 6.1 | Machine is switched off using correct ‘power off’ procedures |
| | 6.2 | Machine is cleaned and programmed maintenance, which is within the province of the operator, is performed in accordance with enterprise requirements and manufacturer’s specifications while observing all relevant WHS requirements, including the use of material safety data sheets (MSDS) |
| | 6.3 | Worn or damaged needles are disposed of in accordance with safe working practice |
| | 6.4 | Supervisor is notified of any abnormal conditions requiring maintenance or repair |
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
interpreting and applying work instructions and established procedures
planning and coordinating work activities
locating and interpreting technical information about machines and materials used in aircraft life support and furnishing
selecting appropriate needle and thread
identifying unsatisfactory machine performance
using relevant hand and power tools
using relevant chemicals and cleaning agents and dispose of waste products
maintaining machines and work area
applying all relevant safety practices
communicating effectively within the workplace
documenting and transferring information.
The underlying skills inherent in this unit should be transferable across a range of aircraft life support equipment maintenance activities involving the use of sewing machines/overlockers. It is essential that fabric component manufacture, repair and alteration procedures and safety precautions are fully observed, understood and complied with. Ability to interpret fabric component requirements and apply them in practice is critical.
This is to be demonstrated through demonstration of the ability to perform appropriate manufacturing, repair and alteration tasks that are within the bounds of the individual’s authority.
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:
precautions and safe working practices based on relevant WHS legislation, codes of practice, policies and procedures
advanced work piece construction principles and methods
characteristics of a wide range of materials used in aircraft life support and furnishing
operating principles of a wide range of sewing/overlocking machines
types of needles and threads and their applications
types of stitching and their applications
standard industry practice for needle storage and safe disposal
the range of sewing/overlocking machines, hand tools and power tools used in sewing/overlocking processes and their appropriateness for particular applications
relevant quality standards for sewn/overlocked products
power sources, such as single phase, three phase and weather protected outlets
electrical isolation procedures for sewing/overlocking machines
safety and environmental requirements of relevant industry and enterprise procedures
general housekeeping policies and procedures
recording and reporting procedures.
Access is required to:
real or appropriately simulated situations involving the sewing or overlocking of materials used in aircraft life support equipment and in aircraft soft furnishings
information on specifications of materials used in sewing and overlocking, settings for machines, relevant safety procedures and regulations, quality standards, and enterprise procedures
all necessary facilities, sewing/overlocking machines and associated hand and power tools.
Assessment may occur on the job or in an industry approved simulated environment.
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 a sufficient number of occasions or over sufficient period of time to ensure consistent performance across a typical range of sewing and overlocking requirements performed at the enterprise.
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).
