Elements and Performance Criteria

1. Prepare to perform routine repairs and minor modifications to aircraft internal fittings
   • Applicable repair scheme is determined in accordance with applicable maintenance publications and enterprise procedures
   • All required materials and equipment are selected and organised in accordance with enterprise procedures and maintenance publications
2. Perform routine repairs to aircraft internal fittings
   • Sheet metal repairs and non-metallic material repairs are performed in accordance with approved repair scheme, ensuring that aircraft standard practices are used and standard process requirements are carried out while observing all relevant work health and safety (WHS) requirements, including the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE)
   • Work area is cleaned of all waste material
   • Adjustments are made, where necessary, for components to operate within prescribed specifications
3. Complete routine repair activities
   • Required documentation is accurately completed and correctly processed in accordance with enterprise procedures

Performance Evidence

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying relevant WHS procedures, including the use of PPE and MSDS

using enterprise procedures, approved maintenance documentation and aircraft publications relating to aircraft sheet metal and non-metallic internal fittings

identifying various materials used for internal fittings and their basic properties by interpretation of markings, numbering systems or visual, chemical or mechanical means

handling and storing aircraft metals used for sheet metal internal fittings, including sealing agents, to industry standards

identifying aircraft sheet metal assembly fasteners (metal and non-metallic) by interpretation of markings, numbering systems, size, shape and colour

correctly interpreting applicable repair schemes and hand sketches

using appropriate hand tools and power tools under supervision to remove and assemble aircraft sheet metal internal fittings

performing under guidance and in accordance with enterprise procedures a range of routine metal and non-metal repair techniques

applying corrosion removal/treatment techniques

restoring sealing and surface finishes to repaired areas.

The underlying skills inherent in this unit should be transferable into other areas that require similar techniques. It is essential that procedures take into account all safety precautions and quality requirements, standards and practices, and processes associated with repair and assembly.

Evidence of knowledge about enterprise procedures relating to basic repair techniques and the use of the standard repair manual/practices in a range of different routine repair situations will be necessary to supplement evidence of ability to plan and undertake internal fitting repairs.
