Unit of competency
Modification History
Release 1. Unit title error amended. Application changed. Elements and Performance Criteria changed. Foundation Skills made explicit. Range of Conditions removed, and relevant information moved to Assessment Requirements. Assessment Requirements clarified. Supersedes and equivalent to MEA214 Inspect, test and troubleshoot aircraft basic communication and radio navigation systems and components.
Application
This unit describes the skills and knowledge required to apply hand skills and use system and component knowledge, maintenance publications and test equipment to inspect, test and troubleshoot basic communication and radio navigation systems and components of fixed and rotary wing aircraft during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.
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.
Pre-requisite Unit
MEA206 Remove and install aircraft basic radio communication and navigation system components
MEA246 Fabricate and/or repair aircraft electrical hardware or parts
Competency Field
Aviation maintenance
