Description
This unit describes the skills and knowledge required to apply hand skills and use maintenance publications, drawings, and appropriate jigs, fixtures and tools to disassemble and reassemble aircraft structures during scheduled or unscheduled maintenance. Work may be performed individually or as part of a team.Applications include fixed and rotary wing aircraft.Structural repair and modification is covered by units MEASTR0016 Repair and modify aircraft metal structure or MEASTR0002 Modify and repair aircraft composite materials structures and components. Fabrication of replacement components covered by units MEASTR0014 Fabricate basic structural components for aircraft and MEASTR0015 Fabricate advanced structural components for aircraft.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.
Notes
Elements and Performance Criteria
