Unit Of competency

Modification History

Release 2. Equivalent to MEA508 Maintain, install and remove restraint systems with amended prerequisite codes.

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).

Range of Conditions

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

Restraint belts/harnesses include: 

  • Fixed point attached harness
  • Passenger restraint belts
  • Retractable restraint harnesses (will be attached to inertia reel but the inertia reel does not form part of the restraint system)

Standard procedures are found in any or all of: 

  • Commonwealth/state/territory WHS legislation, regulations and codes
  • Australian Standards
  • Equipment manufacturers’ specifications and procedures
  • Industry practices
  • Safety manuals
  • Maintenance schedules
  • Work instructions
  • Maintenance organisation manuals
  • MSDS
  • Defence regulations and instructions
  • Civil Aviation Safety Regulations (CASRs) and advisory material
  • Standing instructions

Faults include: 

  • Broken quick release fitting springs
  • Broken stitching
  • Contamination
  • Corrosion of metal parts
  • Damaged hardware
  • Damaged quick release fitting screws
  • Excessive wear
  • Expired date of restraint components
  • Incorrect manufacture
  • Pulled threads
  • Seized quick release fitting lugs
  • Ultraviolet (UV) degradation

Parts include: 

  • Belt
  • Fixed point attachment line
  • Hardware (e.g. buckles)

Assessment requirements

Modification History

Release 2. Equivalent to MEA508 Maintain, install and remove restraint systems with amended prerequisite codes.

Performance Evidence

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.

Knowledge Evidence

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).
