Description
Employability Skills
Learning Outcomes and Application This unit of competency requires application of hand skills and the use of system/component knowledge and applicable maintenance publications and test equipment to inspect, test and troubleshoot aircraft advanced instrument systems and components of fixed and rotary wing aircraft during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.The unit is part of the Avionic 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 workplace or simulated workplace using tools and equipment specified in the maintenance manuals. It is also expected that applicable general and special purpose tools, and test and ground support equipment would be used where appropriate.

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 the unit of competency are being achieved under routine supervision on a system and at least (1) one major system component/line replacement unit (LRU) from each of:

pitot/static system components; ASIs; VSIs; air data systems and components; machmeters; altimeters, including servo and encoding altimeters; angle of attack and stall warning/avoidance systems

turn and slip indicators, DGs, AHs, AHRS and components, remote reading gyro compass systems and components, and direct reading compasses

turbine engine indication systems and components (tachometers, pressure, temperature, engine performance and engine vibration)

transmitter/indicator measuring instrument systems (pressure, temperature and position)

fuel quantity indication and flow systems and components

GPWS (may be omitted if not applicable to the enterprise)

FDRs (may be omitted if not applicable to the enterprise).

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 MEA212 Inspect, test and troubleshoot basic aircraft instrument systems and components will have covered inspection, testing and troubleshooting of a range of flight instruments and direct reading compass and measuring systems. The Log of Industrial Experience and Achievement records relating to MEA212 Inspect, test and troubleshoot basic aircraft instrument systems and components may be accepted as also meeting the evidence requirements for this unit in the applicable areas.

Advice provided in MEA212 Inspect, test and troubleshoot basic aircraft instrument systems and components regarding MEA275 Maintain basic light aircraft systems and components should also be considered where applicable.
