Description
This unit describes the skills and knowledge required to apply hand skills and use maintenance publications and knowledge of diesel engine and system theory to inspect, test and troubleshoot, remove and install aircraft diesel engines and engine system components during the performance of scheduled or unscheduled maintenance. Maintenance may be performed individually or as part of a team.This unit applies to diesel engines fitted to light aircraft and 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).Where a CASA or DASA licensing outcome is sought this unit forms part of the requirement for the granting of the chosen maintenance certification licence under the relevant Aviation Safety Regulations, in accordance with the licensing provisions in the MEA Aeroskills Companion Volume Implementation Guide.Any other relevant legislation, industry standards and codes of practice within Australia must be applied.
