Employability Skills | |||
Learning Outcomes and Application | This unit of competency requires application of hand skills, standard trade practices, and systems knowledge in the testing and troubleshooting 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 (Aircraft Maintenance Stream) training pathways and must be taken with MEA318 Inspect aircraft hydro-mechanical, mechanical, gaseous and landing gear systems and components.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 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 approved aerospace 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, as follows: hydraulic systems – a system and at least one (1) component from each of the following hydro-mechanical system component groups: hydraulic accumulators, filters, reservoirs, valves, pumps, motors, actuators, regulators and direct reading gauges rigid and flexible pipelines, hoses and fittings fuel systems – a system and at least one (1) component from each of the following fuel system component groups: fuel system filters, valves, pumps, rigid and flexible storage cells/tanks rigid and flexible pipelines, hoses and fittings landing gear systems – each of the following systems: retraction systems steering systems brake systems, including anti-skid, where applicable landing gear components – one (1) each of: wheel assemblies brake units struts/oleos gaseous systems – each of the following systems: pneumatic air cycle air conditioning pressurisation fire-extinguishing gaseous system components - at least one (1) component from each of the following gaseous system component groups: gauges (direct reading), temperature sensors, pressurisation controllers and temperature controllers heat exchangers, pressure vessels, condensers, compressors, expansion turbines, humidifiers, valves and actuators rigid and flexible pipelines and fittings ducting mechanical systems – a mechanical operating and locking system and at least one (1) component from each of the following mechanical system component groups: cables, pulleys, guides, fairleads, tension regulators, chains and sprockets push/pull rods, torque tubes, bellcranks, screwjacks, clutches, springs, bearings and gears. 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: Element 1 – any one of MEA309 Inspect, test and troubleshoot aircraft hydro-mechanical and landing gear system and components, or MEA310 Inspect, test and troubleshoot aircraft pneumatic systems and components Elements 2 and 3 – MEA309 Inspect, test and troubleshoot aircraft hydro-mechanical and landing gear system and components, for hydro-mechanical system variables, and MEA310 Inspect, test and troubleshoot aircraft pneumatic systems and components, for gaseous system variables. The Log of Industrial Experience and Achievement records relating to the listed units may be accepted as also meeting the evidence requirements for this unit in the applicable Elements for systems and components as listed in the Range of Conditions variables. Advice in MEA310 Inspect, test and troubleshoot aircraft pneumatic systems and components, regarding MEA355 Maintain light aircraft air cycle air conditioning systems, and MEA356 Maintain light piston engine aircraft pressurisation systems, may also be taken into consideration where applicable. |
