Description
This unit of competency applies to aircraft gas turbine engines, engine control, lubrication, inlet anti-ice 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 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 integration of engine and rotor control is covered in unit 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).
