Description
This unit describes the skills and knowledge required to apply hand skills and use maintenance publications and knowledge of two-stroke petrol engine and system theory to inspect, test and troubleshoot, remove and install aircraft two-stroke petrol engines and engine system components during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.Applications include aircraft two-stroke petrol engines driving fixed pitch propellers. Where the engine is driving a constant speed propeller, MEA307 Remove and install propeller systems and components and MEA315 Inspect, test and troubleshoot propeller systems and components, will also be required.The unit is used in workplaces that operate under the airworthiness regulatory systems of the Civil Aviation Safety Authority (CASA) and the Defence Aviation Safety Authority (DASA).Any other relevant legislation, industry standards and codes of practice within Australia must be applied.
