Description | |||
Employability Skills | |||
Learning Outcomes and Application | This unit of competency extends the competencies developed in units MEA202 Remove and install basic aircraft electrical system components and MEA210 Inspect, test and troubleshoot basic aircraft electrical systems and components to include the maintenance of additional electrical systems found in twin piston engine fixed wing aircraft during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.The unit is part of the small aircraft maintenance Certificate IV Mechatronics training pathway. 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 following system and on at least one (1) major component/line replaceable unit (LRU) in each case: DC multi-generator and alternator/rectifier generator regulation and distribution systems and components electrical propeller control systems, such as feathering systems (where applicable to the enterprise) batteries in dual battery installations and associated mounting equipment, including related anti-vibration aids (competency may be demonstrated through the performance of a battery check) fire warning and extinguishing systems, including handling of halogen fire extinguishers (where applicable to the enterprise) combustion heating systems (where applicable to the enterprise) equipment cooling and ventilation fuel storage and distribution systems master and central warning systems (where applicable to the enterprise). Component removal and installation competencies are to be demonstrated on at least one (1) component from each of the following groups: components of multi-generator regulation and distribution systems electrical propeller control system components (where applicable to the enterprise) batteries in dual battery installations and associated mounting equipment, including related anti-vibration aids fire warning and extinguishing system components (where applicable to the enterprise) combustion heaters and associated components (where applicable to the enterprise) equipment cooling and ventilation components fuel storage and distribution system electrical components master and central warning system components (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 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. |
