Unit of competency
Modification History
Release 1 - New unit of competency
Application
This unit of competency applies to aircraft piston engines, engine controls, air inlet, cooling, lubrication and propeller systems, and components thereof. It involves evaluation of power plants and components for compliance with design 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.
Where the engine is installed in a rotorcraft the interface between the engine throttle/governor and the rotor controls is covered in MEA718 Evaluate rotorcraft flight control system.
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).

Assessment Conditions
- 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 piston engine power plants as specified in CM and/or ILS requirements
- assess and apply basic aircraft piston engine power plant design and maintenance/repair requirements, and graphics skills and techniques
- evaluate aircraft piston engine power plant components for compliance with WHS and airworthiness regulatory requirements
