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 to inspect aircraft electronic 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 pathways. 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 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 each type of system listed in the following groups and on at least one (1) component for each listed system type:

electronic instrument displays – EFIS, EICAS, FMS, ECAM and HUD (where applicable to the enterprise)

instrument navigation systems – INS, IRS, compasses and AHRS

communication systems – HF, VHF, UHF, SATCOM, intercom, data and cabin network services, ELT and CVR

radio navigation systems – ADF, VOR, ILS and GNS

pulse operated systems – weather radar, navigation radar, ATC transponder, ADS-B, RADALT, DME, doppler and ACAS (where applicable to the enterprise)

integrated modular avionics (where applicable to the enterprise)

information systems – air traffic and information management, network servers (where 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 National Vocational Education and Training Regulator (NVR)/Australian Quality Training Framework (AQTF) assessor requirements.

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.
