Description | |||
Employability Skills | |||
Learning Outcomes and Application | This unit of competency requires application of hand skills and the use of maintenance documentation/publications in the maintenance of basic aircraft electrical systems and components involving inspection, limited testing and troubleshooting, and component removal and installation during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.Applications include fixed wing aircraft with fixed undercarriage and basic rotary wing aircraft with skids or floats and no powered flight controls powered by either a normally aspirated piston engine or small gas turbine. The unit is part of the small aircraft maintenance Certificate III and IV Mechatronics training pathways. Where a Civil Aviation Safety Authority (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 tools and equipment specified in maintenance documentation. It is also expected that general-purpose tools and test 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 workplace assessor that the relevant elements and performance criteria of the unit of competency are being achieved under routine supervision on electrical looms, cables and connection hardware, and on each of the following systems and on at least one (1) major component/line replaceable unit (LRU) in each case: DC power generation, regulation and distribution systems piston engine and gas turbine engine ignition and starting systems (gas turbine may be omitted where not applicable to the enterprise) DC electrical systems, such as flaps, including related motors and actuators aircraft lighting aircraft main battery (competency may be demonstrated through the performance of a battery check). Component removal and installation competencies are to be demonstrated on at least one (1) component from each of: DC generators, and alternator/rectifier generators, and components of related single generator regulation and distribution systems motors actuators piston engine and gas turbine engine ignition and starting system components (gas turbine may be omitted where not applicable to the enterprise) aircraft batteries aircraft lighting components such as bulbs, lenses, switches and rheostats . 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. |
