Description
Employability Skills
Learning Outcomes and Application This unit of competency requires application of hand skills, standard trade practices and systems knowledge in the inspection, testing and troubleshooting of both fixed and rotary wing aircraft pneumatic systems and components during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.The unit is part of the Mechanical Certificate IV (Aircraft Maintenance Stream) training pathway. The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation safety Authority (CASA). Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

Competency should be assessed in the work environment or simulated work environment, using procedures, tools and equipment specified in maintenance documentation. It is also expected that applicable general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate. The level of troubleshooting is limited in its application to the use of fault diagnosis guides or other similar information.

The application of testing procedures should clearly indicate knowledge of system operation, the relationship of individual components and the links with other systems (if applicable) within the limits of the aircraft/system fault-finding guide before undertaking any action. 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 this unit of competency are being achieved under routine supervision on each type of system:

de-icing

air cycle air conditioning

pressurisation

fire-extinguishing

and on at least one (1) component from each of the following groups:

filters, valves, pumps, motors, actuators and regulators

gauges (direct reading), temperature sensors, pressurisation controllers and temperature controllers

heat exchangers, pressure vessels, condensers, compressors, expansion turbines and humidifiers

rigid and flexible pipelines, hoses and fittings

ducting.

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).

Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.

Individuals being assessed who have already attained MEA355 Maintain light aircraft air cycle air conditioning systems, and/or MEA356 Maintain light piston engine aircraft pressurisation systems will have satisfied the requirements of this unit with regard to common Range of Conditions variables. The Log of Industrial Experience and Achievement records relating to MEA355 Maintain light aircraft air cycle air conditioning systems, and/or MEA356 Maintain light piston engine aircraft pressurisation systems may be accepted as also meeting the evidence requirements for this unit in the applicable common areas.
