Modification History
New unit.
Unit Descriptor
This unit of competency is part of the Aeroskills Structures Maintenance Certificate IV training pathway. It covers the competencies required to fabricate by hand and in accordance with specifications and drawings basic structural components for aircraft that are either flat or have only a single curve. The unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.
Application of the Unit
This unit requires application of hand skills and the use of drawings, specifications and maintenance publications to fabricate basic structural components requiring hand forming only from aluminium alloys and steel alloys at various states of temper.
Applications include components for fixed and rotary wing aircraft.

Evidence Guide
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 basic 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 basic structural fabrication techniques and their application to different materials used in aircraft manufacture will be required to supplement evidence of ability to fabricate basic aircraft structural 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 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 by aircraft maintenance manuals. It is expected that general purpose tools and test equipment found in most routine situations would be used where appropriate. |
