Description
This unit describes the skills and knowledge required to apply hand skills and use system and component knowledge and applicable test equipment to inspect, test and troubleshoot basic aircraft instrument systems and to remove and install components during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.Applications include light fixed wing aircraft with fixed undercarriage and basic rotary wing aircraft with skids or floats and no powered flight controls powered by either a normally aspirated piston engine or small gas turbine. 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.
