Description
This unit is part of the Aeroskills Structures Maintenance Certificate IV training pathway. It covers the competencies required for the repair of fixed and rotary wing aircraft. No licensing requirements apply to this unit at the time of publication.
Notes
Elements and Performance Criteria
1. Prepare to undertake repair
- 1.1. Extent of damage is correctly assessed to assist in determining repair 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 modification or repair scheme 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 repair scheme cannot be identified or damage is out of limits.
- 1.5. All materials and equipment required are organised.
2. Repair/modify aircraft structure
- 2.1. Structural repairs are performed, in accordance with approved repair scheme, ensuring that aircraft standard practices are used and process requirements are carried out.
- 2.2. Work area is cleaned of all waste material or contaminants.
- 2.3. Components are adjusted, where necessary, to operate within prescribed specifications.
- 2.4. Repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures, where required.
- 2.5. Required documentation is completed and processed in accordance with standard enterprise procedures
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.
Repair procedures
Repair procedures may include:
1. Remove corrosion by chemical and mechanical methods
2. Restore protective coatings
3. Apply sealants and jointing compounds
4. Freehand precision hole generation
5. Remove and install structural hardware, fastening devices, bushes, bearings and bearing surfaces
6. Remove and repair damaged sections and reinstall
7. Minor repairs to non-metallic materials.
Procedures and requirements
Refer to industry standard specified by manufacturers, regulatory authorities or the enterprise.

EVIDENCE GUIDE
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, use special tools and structural repair manuals and schemes to repair aircraft structure 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 item from each of Groups 1 to 7 listed 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.
