Tips for gathering evidence to demonstrate your skills

The important thing to remember when gathering evidence is that the more evidence the better - that is, the more evidence you gather to demonstrate your skills, the more confident an assessor can be that you have learned the skills not just at one point in time, but are continuing to apply and develop those skills (as opposed to just learning for the test!). Furthermore, one piece of evidence that you collect will not usualy demonstrate all the required criteria for a unit of competency, whereas multiple overlapping pieces of evidence will usually do the trick!

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria under the specified conditions of assessment, and must include:

applying all relevant WHS procedures, including the selection and use of MSDS and applicable items of PPE

identifying damage to aircraft metallic (ferrous and non-ferrous) structures and/or components by way of impact, fatigue or the various types of corrosion

inspecting damage and assessing composite components/structures

identifying various aircraft metals and their basic properties

identifying composite materials used in aircraft construction, associated safety precautions and hazards

correctly interpreting repair scheme drawings, including third angle projection, isometric, sectional formats and hand sketches

using appropriate hand tools and machines, including riveting equipment, drilling equipment, aligning tools and material fasteners (grip pins)

applying correct removal, installation and repair techniques for:

a range of rivets (blind and solid) using hand, squeeze and pneumatic situations

a range of close tolerance fasteners (standard and oversize – hillocks and taper locks), including hole preparation

threaded devices, including internal and external thread cutting, Helicoil inserts and damaged stud replacement

hardware assembled by close tolerance fits using heat, cooling and force methods, including bearings, bushes and inserts

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 structure is essential. This may be demonstrated through application across a number of aircraft structures or aircraft types. Ability to interpret inspection and repair procedures and specifications and apply them in practice is critical.
