Required Skills and Knowledge

Required skills 

Look for evidence that confirms skills in:

  • applying OHS practices relating to restraint system maintenance processes, including the selection and correct use of PPE, where applicable
  • handling, storing and organising transport of equipment
  • using MSDS
  • using maintenance publications, drawings and documentation relating to restraint system maintenance
  • using applicable testing and measuring equipment, tools and maintenance documentation to:
  • replace unserviceable components in accordance with approved procedures
  • select and use appropriate restraint system cleaning materials
  • repair restraint systems (both hand and machine sewing)
  • cleaning and maintaining equipment and tools

Required knowledge 

Look for evidence that confirms knowledge of:

  • relevant regulations, standards, enterprise procedures and maintenance publications
  • OHS procedures relating to restraint system maintenance, including the selection and use of PPE
  • how to obtain MSDS
  • critical nature of maintaining and fitting restraint systems
  • approved cleaning methods for aviation life support equipment
  • components of a restraint system and their function
  • flight line procedures
  • UV degradation
  • types of corrosion and contamination that may affect restraint systems
  • handling, storage and transit procedures relating to life support equipment
  • modification requirements for restraint systems
  • operation of testing and measuring equipment and tools used to maintain restraint systems
  • repair limitations for restraint systems

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 maintain, install and remove restraint systems 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. It is essential that restraint system inspection procedures, cleanliness requirements, repair procedures and safety precautions are fully observed, understood and complied with. Ability to interpret maintenance, installation and removal procedures and apply them in practice is critical.

Evidence of transferability of skills and knowledge related to restraint system maintenance, installation and removal is essential. This is to be demonstrated through demonstration of the ability to recognise faults, replace components and perform appropriate repairs that are within the bounds of the individual's authority, and through the demonstration of correct installation and removal 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 the inspection, repair, installation and removal of restraint systems, including the demonstration of the ability to recognise a range of faults and their serviceability and repair limitations/tolerances (must include verification of expiry dates of restraint system component parts and recognition of incorrect manufacture). 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.

Method of assessment
