Elements and Performance Criteria

  1. Determine requirements
  2. Troubleshoot pneumatic components
  3. Dismantle and inspect pneumatic parts
  4. Repair and/or modify pneumatic components or parts
  5. Assemble, test and adjust pneumatic components

Range Statement

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.

Pneumatic components from pressurisation, air cycle air conditioning and pneumatic systems include:

Valves, pumps, motors, expansion turbines, actuators, regulators, temperature sensors, mechanical pressurisation controllers, temperature controllers and thrust reversers

Heat exchangers and pressure vessels

Rigid and flexible pipelines, hoses, fittings and ducting

Repair of component parts includes:

Finishing or re-finishing of metal surfaces through processes, such as polishing and lapping

Removal of corrosion within maintenance manual limits

Replacement of seals and backing rings

Replacement of bearings

Application of surface treatments, such as alodining

Restoration of paint finishes

Testing and adjustment:

Complex testing and adjusting of components, where required, will be carried out under supervision at the appropriate level

Procedures and requirements include:

Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

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 relevant WHS procedures

using MSDS and relevant items of PPE

using relevant maintenance documentation and aircraft/component manuals relating to pneumatic, pressurisation and air cycle air conditioning system components to:

recognise state of serviceability and overhaul or repair requirements

test and accurately and efficiently troubleshoot unserviceabilities and document the causes

dismantle and inspect component parts for serviceability and identify repair requirements as applicable

repair/replace/modify component parts

assemble, test for correct operation and adjust components.

The underlying skills inherent in this unit should be transferable across a range of repair and/or overhaul applications associated with aircraft components. It is essential that the maintenance procedures are interpreted and applied to ensure quality and safety standards are achieved.

This shall be demonstrated through application across a number of different aircraft components. Ability to assess component serviceability and interpret parts requirements will be necessary to supplement the required evidence. Capability to interpret inspection procedures and specifications (allowable limits) and apply them in practice is critical.
