Evidence Required

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

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.

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
