Unit of competency
Modification History
Release 1. Equivalent to MEA419 Inspect and repair/modify aircraft cabin/cockpit non-primary structure components. Revised as a result of changed prerequisites. Unit codes updated.
Application
This unit of competency describes the skills and knowledge required to inspect non-primary metallic and non-metallic structure components in aircraft cabins and cockpits for damage, and to repair the components. It requires the application of hand skills and the use of maintenance publications. Work may be performed individually or as part of a team.
The unit applies to fixed and rotary wing aircraft cabins and cockpits during scheduled and unscheduled maintenance. It is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
This unit forms part of the Civil Aviation Safety Authority (CASA) requirement for maintenance certification licences under Civil Aviation Safety Regulation (CASR) Part 66. Where a CASA licensing outcome is sought, users must refer to the licensing provisions in the MEA Aeroskills Companion Volume Implementation Guide.

Performance Evidence
There must be evidence the candidate has completed the tasks outlined in the elements and performance criteria of this unit, which must include the ability to:
- inspect the metallic components of one aircraft cabin or cockpit for damage and perform the following repair or minor modification tasks:
- remove corrosion by chemical and mechanical methods
- restore protective coatings
- freehand precision hole generation
- remove and install fastening devices
- fit patches to cabin or cockpit non-primary structure sheet metal components
- inspect the non-metallic components of one aircraft cabin or cockpit for damage and perform the following repair or minor modification tasks:
- composite patch, scarf and stepped repairs using fibreglass, sandwich honeycomb, nylon, Perspex, nomex core materials and matrix resins.
In the course of the above work, the candidate must:
- apply relevant WHS requirements and practices relating to:
- use of safety data sheets (SDS)
- selection and use of required items of personal protective equipment (PPE)
- use organisational procedures, approved maintenance documentation, and aircraft publications relating to non-primary structure metallic and non-metallic components of cabins and cockpits
- identify aircraft cabin/cockpit non-primary structure components and their basic properties by interpreting markings, numbering systems or visual, chemical or mechanical means
- handle and store aircraft metallic and non-metallic components, including sealing agents, to industry standards
- identify aircraft assembly fasteners by interpreting markings, numbering systems, size, shape and colour
- visually inspect metallic and non-metallic components for damage
- correctly interpret, in line with organisational procedures, applicable repair scheme/modification drawings and hand sketches
- use required hand tools and machines to remove and assemble non-primary structure metallic and non-metallic components of aircraft cabins and cockpits
- perform, in line with organisational procedures, a range of routine non-primary structure sheet metal repair techniques, including metal scab patch repairs
- perform, in line with organisational procedures, a range of routine non-primary structure non-metallic repair techniques
- apply corrosion removal and treatment techniques
- restore sealing and surface finishes
- comply with system testing procedures, cleanliness and quality requirements, and safety precautions applicable to repair or modification being performed
- complete and process maintenance documentation.
