Elements of Competency Performance Criteria              
Element: Interpret specifications and organise materials
  • Specifications and drawings are interpreted to determine material requirements.
  • Procedure for fabricating component is determined in order to plan equipment use.
  • Material is correctly identified to meet specifications.
  • All materials and equipment are organised.
       
Element: Prepare material and tooling
  • Dimensions are translated to material in accordance with specifications.
  • Cutting and forming equipment is prepared and adjusted to ensure accuracy of fabrication.
  • Material is cut according to specifications ensuring minimisation of wastage and maintenance of surplus material identification.
  • Material requiring special treatment is made ready for the appropriate processes.
  • Solution treatment of materials is carried out in accordance with approved procedures and specifications.
       
Element: Form material
  • Appropriate forming procedure is determined which ensures specifications are met and the most suitable method selected.
  • Forming equipment is operated correctly and safely.
  • Hand forming is accurately carried out where necessary.
  • Material is formed to meet specifications.
       
Element: Hand correction of fabricated components

Element: Inspect components
  • Fabricated components are inspected to confirm dimensional accuracy and specifications are met.
  • Checking fixtures are used where appropriate to ensure requirements are met.
  • Components requiring special or further treatment are made ready for the appropriate processes.
  • Completed components are tagged or identified as required.
       


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 hand skills and use drawings, specifications and maintenance publications to fabricate aircraft structural components from a range of aircraft metals 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 aircraft applications. It is essential that procedures take into account all safety precautions and quality requirements. Skill and knowledge application must include set back, bend allowance and other standard practices associated with forming of material.

Evidence of knowledge and skills associated with the broad range of structural fabrication techniques and their application to different materials used in aircraft manufacture will be required to supplement evidence of ability to fabricate components.

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 a representative range of structural fabrication tasks. 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 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:

application of applicable OH&S procedures

the use of approved maintenance documentation and aircraft publications relating to aircraft structure

identifying various aircraft metals and their basic metallurgy properties by interpretation of markings, numbering systems or visual, chemical or mechanical means

handling and storing aircraft metals to industry standards

identifying aircraft structural assembly fasteners by interpretation of markings, numbering systems, size, shape and colour

fabrication of aircraft structural components and parts by:

correctly interpreting drawings (including third angle projection, isometric, sectional formats and hand sketches)

developing component flat pattern using basic drawing tools, geometric drawing processes, parallel, radial and triangulation methods, calculating and applying bend allowance/deduction/setback (an understanding of flat pattern development terminology is required)

using appropriate hand tools, machines (stretching, shrinking, bending, cutting, drilling, rolling, wheeling and folding), forming blocks, templates, presses to form/produce dished, domed, curved components, bent/angled (L, Z, U, hat) sections and lightning holes, flanges, joggles

assembling component parts using appropriate hand and machine tools and standard aircraft fasteners to industry standards

applying appropriate metal heat treatment processes

applying appropriate metal surface treatments

Required knowledge

Look for evidence that confirms knowledge of aircraft construction principles

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.

Competency is to be assessed:

using materials comprising various types of sheet metal used in aircraft manufacture, including aluminium alloys and structural steel alloys across a range of temper.

Machinery processes are to include:

bending, cutting, rolling, shrinking and stretching.

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.
