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.
   • 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.

Required Skills

Required skills

Look for evidence that confirms skills in application of relevant OHampS procedures the use of 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 removaltreatment techniques restoring aircraft structure sealing and surface finishes

Required knowledge

Look for evidence that confirms knowledge of aircraft construction principles

Evidence Required

The Evidence Guide provides advice on assessment and must be read in conjunction with the performance criteria required skills and knowledge range statement and the Assessment Guidelines for the Training Package
Overview of assessment	A person who demonstrates competency in this unit must be able to apply hand skills and use maintenance publications to remove corrosion damage from aircraft structural materials while applying all relevant safety precautions
Critical aspects for assessment and evidence required to demonstrate competency in this unit	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 assembly Evidence of knowledge about repair techniques and the use of the standard repair manual in a range of different repair situations will be necessary to supplement evidence of ability to plan and undertake structure and component repair A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the Unit of Competency are being achieved under routine supervision on at least one task from each of Groups to in the Range Statement This shall be established via the records in the Log of Industrial Experience and Achievement or where appropriate an equivalent Industry
Context of and specific resources for assessment	Competency should be assessed in the work environment using tools and equipment specified by aircraft maintenance manuals It is also expected that general purpose tools test and ground support equipment found in most routine situations would be used where appropriate
Method of assessment

Range Statement

The range statement relates to the unit of competency as a whole. It allows for different work environments and situations that may affect performance. Bold italicised wording, if used in the performance criteria, is detailed below. Essential operating conditions that may be present with training and assessment (depending on the work situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) may also be included.
Note	The Range Statements below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide.
Corrosion removal procedure	Corrosion removal procedure may include: 1. Removing corrosion by chemical and mechanical methods 2. Restoring protective coatings 3. Applying sealants and jointing compounds
	Application of this unit may relate to: scheduled or unscheduled maintenance individual or team related activities
Procedures and requirements	Refer to industry standard specified by manufacturers, regulatory authorities or the enterprise
