MEA436 — Inspect, repair and modify non-primary structure components in aircraft cabins and cockpits

Elements & performance criteria

Performance evidence

• 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.
• 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
