Unit Descriptor
This unit of competency is part of the Aeroskills Life Support and Furnishing Certificate III and IV training pathways. It covers the competencies required to maintain sewing machines and overlockers. This unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA. This unit is equivalent to unit LMTPRTF05A Operate and maintain sewing machines - 3 which was deleted from a revised version of its parent Training Package, but the content remains valid for Aeroskills Life Support and Furnishing. |
Application of the Unit
This unit requires application of skills and knowledge relating to the operation and maintenance of sewing machines and overlockers in the maintenance of items of aircraft life support equipment and in the fabrication and maintenance of items of aircraft soft furnishings. The unit applies to sewing machines and overlockers used in the range of tasks mentioned above. |

Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
1. Plan work and prepare work area |
1.1. Work is planned to maximise safety and productivity 1.2. Work area is cleared and cleaned to provide work table free of obstructions and clear access to sewing/overlocking machine 1.3. Safe working environment is established 1.4. Suitable electrical power outlets, if required, are identified 1.5. Assistance to move and position workpiece is obtained, if necessary |
2. Select thread and needle |
2.1. Type of material to be sewn, type of stitch to be used and nature of duty to which finished product is to be subjected is determined to assist in selection of thread and needle 2.2. Suitable thread is selected with regard to thread material, diameter of thread, tensile strength and colour 2.3. Appropriate needle is chosen to suit type of thread, type of stitch and material to be sewn |
3. Set up machine |
3.1. Machine is examined for damage, missing components or other defects 3.2. Power cords are examined for knots, unsafe routing and insulation damage 3.3. Machine is safely connected to power and correct 'power-on' procedure is followed 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 and OHS 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. Undertake 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 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 Guide
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 operate and maintain sewing and overlocking machines used in aircraft life support and furnishing while observing all relevant safety precautions. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
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. Evidence of transferability of skills and knowledge related to the use and maintenance of sewing machines and overlockers is essential. 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. 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 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 This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide. |
