Description
This unit is part of the Aeroskills Life Support and Furnishing Certificate III and IV training pathways. It covers the competencies required to maintain and fit helmets that are capable of housing communications equipment. Maintenance involves inspecting, testing, isolating faults, replacing parts and sending away for repair, cleaning and testing prior to placing the item back in service. Fitting a helmet includes adjusting the helmet to fit the individual (helmets are not an off-the-shelf issue). This unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.This unit is equivalent to PUADEFLS002B Maintain and fit helmets.
Notes
Elements and Performance Criteria
1. Maintain helmet
  • 1.1. Helmet is inspected for serviceability in accordance with standard procedures
  • 1.2. Helmet is tested for serviceability in accordance with standard procedures and manufacturer's specifications
  • 1.3. Identified faults beyond own authority to rectify are reported to supervisor and faulty helmet is quarantined
  • 1.4. Unserviceable parts of the helmet are replaced in accordance with standards procedures
  • 1.5. Communication system components are tested in accordance with standard procedures
  • 1.6. Helmet is cleaned in accordance with standard procedures
  • 1.7. Helmet is presented for inspection by supervisor in accordance with standard procedures
  • 1.8. Maintenance documentation is completed and processed in accordance with standard enterprise procedures
2. Fit helmet
  • 2.1. Fitting process is explained to the participant so that optimal fit can be achieved through relevant feedback
  • 2.2. Participant is measured to select an appropriate size helmet
  • 2.3. Components of helmet are adjusted to optimise fit
  • 2.4. Helmet fit is verified through participant feedback and by the supervisor
  • 2.5. Relevant documentation is completed and processed in accordance with standard enterprise procedures

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 maintain and fit helmets while using the correct PPE and 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. It is essential that helmet testing and inspection procedures, cleanliness requirements and safety precautions, including the correct use of PPE, are fully observed, understood and complied with. Ability to interpret maintenance and fitting procedures and apply them in practice is critical.
Evidence of transferability of skills and knowledge related to helmet maintenance and fitting is essential. This is to be demonstrated through demonstration of the ability to recognise faults and damage and perform appropriate repairs that are within the bounds of the individual's authority, and through the demonstration of correct fitting procedures. 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 at least three (3) unserviceable helmets providing a representative range of maintenance tasks and on the correct fitting of helmets to at least three individuals. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.
Context of and specific resources for assessment
Competency should be assessed in the workplace or simulated workplace using materials, tools and equipment specified in the maintenance manuals and applicable procedures. It is also expected that general and special purpose tools and ground support equipment would be used where appropriate.
