Description
This unit of competency is part of the Mechanical Certificate IV (Aircraft Maintenance Stream) training pathway. It covers the competencies required to inspect and repair aircraft wooden structures. Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen Aircraft Maintenance Engineer Licence under CASR Part 66, in accordance with the licensing provisions in Section 3, Assessment Guidelines.
Notes
Elements and Performance Criteria
1. Inspect aircraft wooden structure
  • 1.1. Relevant maintenance documentation and modification status, including defect reports, where relevant, are used to identify specific inspection requirements
  • 1.2. Appropriate preparation and access to the aircraft structure is undertaken to allow for proper inspection and testing in accordance with maintenance documentation
  • 1.3. Aircraft wooden structure is visually or physically checked for signs of deterioration, deformation defects or damage in accordance with maintenance documentation and approved procedures
  • 1.4. Damage or defects are assessed against damage or wear limits specified by structural repair manual or other approved data to determine if repair or replacement is required
2. Repair aircraft wooden structure
  • 2.1. Extent of deterioration or 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 structural repair manual and/or approved data
  • 2.4. Specialist advice is obtained in establishing an approved repair scheme where a standard repair scheme cannot be identified or damage is beyond limits
  • 2.5. All materials and equipment required are organised
  • 2.6. Structural repairs are performed, in accordance with approved repair scheme, ensuring that aircraft standard practices are used and process requirements are carried out
  • 2.7. Finishing scheme is restored
  • 2.8. Work area is cleaned of all waste material or contaminants
  • 2.9. Components are adjusted, where necessary, to operate within prescribed specifications
  • 2.10.Required maintenance/repair documentation is completed and processed in accordance with standard enterprise procedures
  • 2.11.Where required, repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures
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
Range statements listed below are numbered to facilitate specification of the assessment requirements included in the Evidence Guide

4. Structural timbers and bolt holes
5. Glued joint strength
6. Glue lines
Inspection techniques may include:
visual inspection, physical checks, mensuration and alignment
Repair
Repair of:
7. Load carrying structural timbers
8. Plywood skin
9. Spars and ribs
Finishing scheme
10. Refinishing of structure after repair using approved finishing scheme
Application
Application of this unit may relate to:
scheduled or unscheduled maintenance
individual or team-related activities
Procedures and requirements
Refer to industry standard procedures 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 woodworking hand skills and use applicable tools and maintenance publications to inspect and repair aircraft wooden structures 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 across a range of inspection, testing and repair applications associated with maintenance of aircraft wooden structures. It is essential that the procedures take into account all aircraft and personal safety precautions relating to aircraft structure.
Evidence of transferability of skills and knowledge related to inspection, testing and repair of aircraft wooden structures is essential. This may be demonstrated through application across a range of aircraft wooden structures. Ability to interpret inspection 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 10 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.
