(a) Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy allof the requirements of the elements and performance criteria under the specified conditions ofassessment, and must include:

• Applying relevant WHS practices, including the use of MSDS and PPE.

• Using relevant maintenance documentation and aircraft manuals to:

• Locate and correctly remove and install components in pneumatic systems, including.

• Fire-extinguishing systems.

• Locate and correctly remove and install components in air cycle air conditioning.

• Systems.

• Locate and correctly remove and install components in pressurisation systems.

• Correctly remove and install rigid and flexible pipelines.

• Correctly remove and install ducting.

• Observing regulations governing the handling and custody of fire-extinguishers containing.

ODS or SGG extinguishing agents (e.g. BCF).

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, andof safe handling of heavy components.

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 componentsinclude:

• 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.

• Fire-extinguishers, including those containing ozone depleting substances (ODS) or synthetic greenhouse gas SGG) extinguishing agents (e.g. BCF) (where applicable to the enterprise)

Procedures and requirements include:

• Industry standard procedures specified by manufacturers,

regulatory authorities or the enterprise.

• The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.

• Competency should be assessed in the work environment or simulated work environmentusing tools and equipment specified in maintenance manuals. It is also expected thatgeneral-purpose tools, test and ground support equipment found in most routine situationswould be used where appropriate.

• An understanding of system operation as it relates to the work must be demonstratedbefore undertaking any action. The work plan should take account of applicable safety andquality requirements in accordance with the industry and regulatory standards.

• A person cannot be assessed as competent until it can be demonstrated to the satisfactionof the workplace assessor that the relevant elements and performance criteria of the unit ofcompetency are being achieved under routine supervision on one (1) item from each fromthe following groups:filters, valves, pumps, motors, actuators and regulatorsgauges (direct reading), temperature sensors, pressurisation controllers andtemperature controllers, heat exchangers, pressure vessels, condensers, compressors, expansion turbines andhumidifiersrigid and flexible pipelines, hoses and fitting ductingfire-extinguishers, including those containing ODS or SGG extinguishing agents (e.g.BCF) (may be omitted where not applicable to enterprise).

• This shall be established via the records in the Log of Industrial Experience and a chievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
