MEA231 Inspect, test and troubleshoot rotary wing aircraft automatic flight control systems and components

Release: 1

MEA231 Inspect, test and troubleshoot rotary wing aircraft automatic flight control systems and components

Modification History

Release 1 - New unit of competency

Application

This unit of competency requires application of hand skills and the use of system/component knowledge and applicable maintenance publications and test equipment to inspect, test and troubleshoot rotary wing automatic flight control systems and components of rotary wing aircraft that have automatic flight control systems during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.

The unit is part of the Avionic Certificate IV (Aircraft Maintenance Stream) training pathway and is an alternative unit to MEA225 Inspect fixed wing aircraft automatic flight control systems and components and MEA230 Test and troubleshoot fixed wing aircraft automatic flight control systems and components.

The 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).

Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.
