Elements and Performance Criteria

1. Prepare to remove corrosion damage
   • Extent of damage is correctly assessed to assist in determining removal procedure
   • Structure is supported and prepared in accordance with the applicable maintenance manual to ensure personnel safety and freedom from damage
   • Appropriate corrosion removal procedure is identified in accordance with structural repair manual and/or approved data
   • Specialist advice is obtained in establishing an approved repair scheme where a standard corrosion removal procedure cannot be identified or damage criteria is out of limits
   • All materials and equipment required are organised
2. Remove corrosion damage
   • Corrosion removal is performed and protective coatings, sealants and jointing compounds applied in accordance with approved repair scheme ensuring that aircraft standard practices are used and process requirements are carried out including relevant work health and safety procedures and the use of material safety data sheets (MSDS) and items of personal protective equipment (PPE)
   • Structure/component is cleaned of all waste material or contaminants
   • Components are adjusted, where necessary, to operate within prescribed specifications
   • Required maintenance/repair documentation is completed and processed in accordance with standard enterprise procedures
   • Repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures, where required

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 all relevant WHS procedures, including the use of MSDS and selection and use of applicable items of PPE

using approved maintenance documentation and aircraft publications relating to aircraft structure

identifying various aircraft metals and their basic metallurgy properties by interpretation of markings, numbering systems or visual, chemical or mechanical means

applying structural corrosion removal/treatment techniques

restoring aircraft structure sealing and surface finishes.

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, practices and processes associated with corrosion removal.
