Elements and Performance Criteria Pre-Content
Elements describe the essential outcomes of a unit of competency. |
Performance criteria describe the performance needed to demonstrate achievement of the element. Where bold italicised text is used, further information is detailed in the required skills and knowledge section and the range statement. Assessment of performance is to be consistent with the evidence guide. |
Elements and Performance Criteria
1. Inspect/test aircraft fabric surfaces |
1.1. Relevant maintenance documentation and modification status, including defect reports, where relevant, are used to identify specific inspection /testing requirements 1.2. Appropriate preparation and access to the aircraft structure is undertaken to allow for proper inspection in accordance with maintenance documentation 1.3. Aircraft fabric-covered surfaces are inspected/tested for signs of damage, deterioration or loss of tensile strength in accordance with maintenance documentation and approved procedures 1.4. Damage or deterioration is assessed against limits specified by maintenance manual or other approved data to determine if repair , restoration or replacement is required |
2. Repair aircraft fabric surfaces |
2.1. Extent of damage is correctly assessed to assist in determining repair procedure 2.2. Structure is supported and prepared in accordance with the applicable maintenance manual to ensure personal safety and freedom from damage 2.3. Appropriate repair scheme is identified in accordance with maintenance manual and/or approved data 2.4. All materials and equipment required are organised 2.5. Fabric repairs are performed, in accordance with approved repair scheme, ensuring that aircraft standard practices are used and process requirements are carried out 2.6. Work area is cleaned of all waste material or contaminants 2.7. Components are adjusted and/or re-balanced, where necessary, to operate within prescribed specifications 2.8. Required maintenance/repair documentation is completed and processed in accordance with standard enterprise procedures 2.9. Where required, repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures |

Overview of assessment |
A person who demonstrates competency in this unit must be able to apply hand skills, knowledge of fabric surfaces and maintenance publications to inspect, test and repair aircraft fabric surfaces. |
Critical aspects for assessment and evidence required to demonstrate competency in this unit |
The underlying skills inherent in this unit should be transferable across a range of inspection and testing applications associated with maintenance of 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. Evidence of transferability of skills and knowledge related to inspection, testing and repair of aircraft fabric surfaces is essential. This may be demonstrated through application across a range of aircraft fabric surfaces. Ability to interpret inspection, testing and repair procedures and specifications (allowable limits) and apply them in practice is critical. The application of the procedures should also clearly indicate knowledge of structural flight loads. 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 all items in each of Groups 1 to 9, as 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 Evidence Guide. |
Context of and specific resources for assessment |
Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance documentation. It is also expected that general purpose tools and test equipment found in most routine situations would be used where appropriate. |
