Description
This unit of competency is part of the Mechanical Certificate IV (Aircraft Maintenance Stream) training pathways. It covers the competencies required to remove corrosion damage from the structure and structural components of fixed or rotary wing aircraft. The unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA. Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen B1 maintenance certification licence under CASR Part 66, in accordance with the licensing provisions in Section 3, Assessment Guidelines.
Notes
Elements and Performance Criteria
1 Prepare to remove corrosion damage
- 1.1 Extent of damage is correctly assessed to assist in determining removal procedure
- 1.2 Structure is supported and prepared, in accordance with the applicable maintenance manual, to ensure personnel safety and freedom from damage
- 1.3 Appropriate corrosion removal procedure is identified in accordance with structural repair manual and/or approved data
- 1.4 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
- 1.5 All materials and equipment required are organised
2 Remove corrosion damage
- 2.1 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
- 2.2 Structure/component is cleaned of all waste material or contaminants
- 2.3 Components are adjusted, where necessary, to operate within prescribed specifications
- 2.4 Required maintenance/repair documentation is completed and processed in accordance with standard enterprise procedures
- 2.5 Repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures, where required
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
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

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 corrosion removal.
Evidence of knowledge about corrosion removal techniques and limits 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 by removal of corrosion within applicable limits.
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 1 to 3 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 Evidence Guide.
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.
