Application
This unit of competency requires application of skills and knowledge relating to the maintenance, installation and removal of personal restraint systems. Maintenance may be performed in-situ or in a maintenance workshop and involves inspection, fault diagnosis, replacement of parts, completion of repairs and cleaning during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.
The unit applies to a range of personal restraint systems.
The unit is part of the Aeroskills Life Support and Furnishing Certificate III and IV training pathways. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).

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 WHS 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 maintenance of equipment and tools.
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.
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.
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:
relevant regulations, standards, enterprise procedures and maintenance publications
WHS 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
ultraviolet (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.
Assessment Conditions
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.
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 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 (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.
