MEA252 Test, align and troubleshoot aircraft synchro and servo system components

Release: 2

MEA252 Test, align and troubleshoot aircraft synchro and servo system components

Modification History

Release 2. Equivalent to MEA252 Test, align and troubleshoot aircraft synchro and servo system components with amended prerequisite codes.

Application

This unit of competency requires application of hand skills, test equipment and knowledge of analogue theory to test, align and troubleshoot synchro and servo components, from fixed and rotary wing aircraft, that are repaired or overhauled in aviation maintenance workshops 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 (Component Maintenance Workshop Stream) training pathways.

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).

Pre-requisite Unit

MEA201	Remove and install miscellaneous aircraft electrical hardware/components
MEA261	Use electronic test equipment
MEA296	Use electrical test equipment in aviation maintenance activities

Competency Field
