Unit of Competency MEA721 - Evaluate aircraft hydro-mechanical systems
Description
Employability Skills
Learning Outcomes and Application This unit of competency applies to hydraulic power, landing gear, fuel storage and distribution, water and waste, and mechanical systems and their components. It involves evaluation of systems and components for compliance with design and performance standards and with airworthiness regulatory requirements within both civil and military environments. Also covered is documentation of the evaluation process within management systems, such as configuration management (CM) and integrated logistic support (ILS).It is suitable for people working as paraprofessionals within aircraft design teams, within the engineering departments of aircraft maintenance organisations or employed within Continuing Airworthiness Management Organisations (CAMOs) and Approved Engineering Organisations (AEOs), and for those pursuing qualifications or careers in those fields.This 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).
Duration and Setting X weeks, nominally xx hours, delivered in a classroom/online/blended learning setting.

This unit may be assessed on the job, off the job or a combination of both on and off the job. Where assessment occurs off the job, that is, the candidate is not in productive work, then a simulated working environment must be used that reflects realistic workplace situations and conditions.

The competencies covered by this unit would be demonstrated by an individual working alone or as part of a team.

Where applicable, reasonable adjustment must be made to work environments and training situations to accommodate ethnicity, age, gender, demographics and disability.

Assessment methods must be by direct observation of tasks and include questioning on underpinning knowledge to ensure its correct interpretation and application.

Assessment may be applied under project-related conditions (real or simulated) and require evidence of process.

Assessment must confirm a reasonable inference that competency is able not only to be satisfied under the particular circumstance, but is able to be transferred to other circumstances.

Assessors must be satisfied that the candidate can competently and consistently:

identify and apply WHS, regulatory and risk management procedures

determine parameters and context of tasks, personal, team, technical and professional assistance and support, personnel functions and responsibilities, and chain of responsibility

investigate sustainability implications of aircraft hydro-mechanical system applications as specified in CM and/or ILS requirements

assess and apply basic aircraft hydro-mechanical system design and maintenance/repair requirements, software basic analysis and graphics skills and techniques

evaluate aircraft hydro-mechanical systems and components for compliance with WHS and airworthiness regulatory requirements

report and document results, including provision of CM and ILS input data.

Assessment may be in conjunction with assessment of other units of competency where required.

Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
