Elements and Performance Criteria

1. Re-cover aircraft fabric surfaces
   • Required covering materials and methods are determined from maintenance manual and/or approved data
   • Required finishing scheme is determined from maintenance manual and/or approved data
   • Materials and equipment required are organised
   • Necessary structure and system inspection and preparation prior to covering is correctly performed 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)
   • Fabric covering is correctly fabricated and attached to the structure
   • Drainage holes are correctly created
   • Applicable finishing scheme is correctly applied while observing all relevant WHS requirements, including the use of MSDS and items of PPE
   • Components are adjusted and/or re-balanced, where necessary, to operate within prescribed specifications
   • Required maintenance/repair documentation is completed and processed in accordance with standard enterprise procedures
   • Where required repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures

Range Statement

This field allows for different work environments and conditions that may affect performance. Essential operating conditions that may be present (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.
Procedures and requirements include:	Industry standard procedures specified by manufacturers, regulatory authorities or the enterprise

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 correct selection and use of PPE and MSDS

using approved maintenance documentation and aircraft publications relating to aircraft fabric surfaces

inspecting structural members, wiring, grommets and system components and initiation of any necessary repair or rectification action

fabricating and fitting fabric covering with appropriately placed inspection panels, zips and drainage holes

applying fabric finishing scheme ready for paint

recognising defective doping.

The underlying skills inherent in this unit should be transferable across a range re-covering applications associated with aircraft fabric surfaces. It is essential that the procedures take into account all aircraft and personal safety precautions, especially with regard to the use of finishing scheme materials.

This shall be demonstrated through application across a range of aircraft fabric surfaces. Ability to interpret re-covering procedures and specifications and apply them in practice is critical.

The application of the procedures should also clearly indicate knowledge of structural flight loads.
