Elements of Competency Performance Criteria              
Element: Inspect aircraft wooden structure
  • Relevant maintenance documentation and modification status, including defect reports, where relevant, are used to identify specific inspection requirements
  • Appropriate preparation and access to the aircraft structure is undertaken to allow for proper inspection and testing in accordance with maintenance documentation
  • Aircraft wooden structure is visually or physically checked for signs of deterioration, deformation defects or damage in accordance with maintenance documentation and approved procedures
  • 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
       
Element: Repair aircraft wooden structure
  • Extent of deterioration or damage is correctly assessed to assist in determining repair procedure
  • Structure is supported and prepared in accordance with the applicable maintenance manual to ensure personal safety and freedom from damage
  • Appropriate repair scheme 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 repair scheme cannot be identified or damage is beyond limits
  • All materials and equipment required are organised
  • Structural repairs are performed, in accordance with approved repair scheme, ensuring that aircraft standard practices are used and process requirements are carried out
  • Finishing scheme is restored
  • Work area 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
  • Where required, repaired components or assemblies are tagged, sealed and packaged or cradled in accordance with specified procedures
       


Evidence Required

List the assessment methods to be used and the context and resources required for assessment. Copy and paste the relevant sections from the evidence guide below and then re-write these in plain English.

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 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 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 .

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.

Assessment Tasks

Copy and paste from the following data to produce each assessment task. Write these in plain English and spell out how, when and where the task is to be carried out, under what conditions, and what resources are needed. Include guidelines about how well the candidate has to perform a task for it to be judged satisfactory.

Required skills

Look for evidence that confirms skills in:

applying relevant occupational health and safety (OHS) procedures, including the correct selection and use of personal protective equipment and material safety data sheets (MSDS)

using approved maintenance documentation and aircraft publications relating to aircraft wooden structure

identifying and using woodworking tools

identifying aircraft structural timbers and their characteristics

identifying potential causes of deterioration in wooden structural components

identifying wooden structure defects and damage

identifying the condition of glue lines

fabricating and fitting repair members

gluing of wooden structure

restoring surface finish after repair

Required knowledge

Look for evidence that confirms knowledge of:

OHS hazards relating to wooden structure repair materials and how to obtain relevant MSDS and personal protective equipment

aircraft wooden construction principles and inspection techniques

wooden structural component attachment methods

the effects of environmental factors on aircraft wooden structures

wooden structure glues and application methods

wooden component assembly methods and testing of joints

wooden structure finishing schemes for exterior and interior surfaces

the application of flight loads to aircraft wooden structural components and joints, and related failure mechanisms

wooden component fabrication and repair techniques

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

Inspection and testing

Inspection and/or testing of:

1. Drainage and water and dirt collection points

2. Fabric covered plywood surfaces

3. Single and double plywood skin

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 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

Copy and paste from the following performance criteria to create an observation checklist for each task. When you have finished writing your assessment tool every one of these must have been addressed, preferably several times in a variety of contexts. To ensure this occurs download the assessment matrix for the unit; enter each assessment task as a column header and place check marks against each performance criteria that task addresses.
