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 of aircraft hydro-mechanical, mechanical, gaseous and landing gear systems and components of fixed wing aircraft 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 Aircraft Maintenance Engineer (AME) Certificate IV 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 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 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 and on at least one (1) component of each group listed in the Range of Conditions, as follows:

cables, pulleys, guides, fairleads, tension regulators, chains and sprockets

control rods, torque tubes, bellcranks, screwjacks, clutches, springs, bearings and gears

control sticks, wheels, columns, trim wheels or handles, and rudder pedals.

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 the following related units will have met the Performance Criteria and Range of Conditions variables for Elements listed:

MEA309 Inspect, test and troubleshoot aircraft hydro-mechanical and landing gear systems and components, for Element 1

MEA309 Inspect, test and troubleshoot aircraft hydro-mechanical and landing gear systems and components, for Element 2, provided that the unit was attained on aircraft with retractable landing gear

MEA310 Inspect, test and troubleshoot aircraft pneumatic systems and components, for Element 3

MEA312 Inspect, test and troubleshoot aircraft fixed wing flight control systems and components, for Element 4.
