Remove and install aircraft pneumatic system components

Assessment tool

Version 1.0
Issue Date: April 2024


This unit requires application of hand skills and the use of maintenance publications to remove and install aircraft pneumatic system components.

Applications include fixed and rotary wing aircraft.

This unit is part of the Aeroskills Mechanical AME Certificate IV training pathways and may also be part of a Structures Certificate IV training pathway. It covers the competencies required for the removal and installation of components in pneumatic systems of both fixed and rotary wing aircraft. Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen Aircraft Maintenance Engineer Licence under CASR Part 66, in accordance with the licensing provisions in Section 3, Assessment Guidelines.

You may want to include more information here about the target group and the purpose of the assessments (eg formative, summative, recognition)

Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 apply hand skills and use maintenance publications to remove and install aircraft pneumatic system components while applying 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 into other units that require similar techniques. It is essential that system cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with.

Evidence of transferability of skills and knowledge related to removal and installation is essential. This may be demonstrated through application across a number of aircraft systems or aircraft types, but must cover a sufficient range of tasks to demonstrate familiarity with attachment methods, connection hardware and couplings peculiar to each type of system, and of safe handling of heavy components. An understanding of system operation as it relates to the work must be demonstrated before undertaking any action. 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 one item from each of Groups 1 to 6 in the Range Statement. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry .

Context of and specific resources for assessment

Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.

Note

Range statements listed below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide.

Pneumatic components

Components may include:

1. Filters, valves, pumps, motors, actuators, regulators

2. Gauges (direct reading), temperature sensors, pressurisation controllers, temperature controllers

3. Heat exchangers, pressure vessels, condensers, compressors, expansion turbines, humidifiers

4. Rigid and flexible pipelines, hoses and fittings

5. Ducting

6. Fire extinguishers including those containing halons (e.g. BCF)

Application of this unit may relate to:
