MEA285 Repair or overhaul aircraft radio frequency communication and navigation system components

Modification History

Release 2. Equivalent to MEA285 Repair or overhaul aircraft radio frequency communication and navigation system components with amended prerequisite codes.

Application

This unit of competency requires application of hand skills, test equipment and knowledge of analogue and digital theory to repair or overhaul radio frequency (RF) components from aircraft communication and navigation systems.

Applications include RF communications and navigation system 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 Workshop Maintenance Stream) training pathway.

Repair of circuit boards is covered by MEA262 Modify/repair aircraft component single layer printed circuit boards and MEA263 Modify/repair aircraft component multi-layer printed circuit boards.

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

MEA261	Use electronic test equipment
MEA296	Use electrical test equipment in aviation maintenance activities
