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 relevant WHS procedures, including lifting and handling of heavy components

using MSDS and PPE

using relevant maintenance documentation and aircraft manuals to:

recognise through visual/physical inspection external and internal signs of defects/damage to gas turbine engine, components and system components

assist with testing of gas turbine engine and engine system operation.

The underlying skills inherent in this unit should be transferable across a range of inspection applications (including the timely involvement of supervisors or other trades) associated with gas turbine engines, components and systems. It is essential that inspection procedures take into account all safety precautions applicable to the system/component being maintained. Ability to interpret system performance specifications (allowable limits) and apply them in practice is critical and shall be demonstrated through application across the range of systems listed in the Assessment Conditions.

Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:

gas turbine engine layout and operation:

intakes

compressors

combustion chambers

turbines

exhaust

thrust reversers

accessory drives

bearings and seals

maintenance requirements

system and component operation, including electrical and instrument system interfaces:

fuel control and fuels

lubrication and lubricants

air distribution

starting

ignition

power augmentation

instrumentation:

condition indication

warning

presentation and interpretation of electronic displays

fire warning and extinguishing

control system

engine spin/run procedures, including the operation of auxiliary power units (APUs)

engine condition monitoring

relevant WHS practices, including the requirements for the lifting and handling of heavy components

how to obtain MSDS

selection and use of PPE

maintenance requirements

relevant maintenance manuals

relevant regulatory requirements and standard procedures.
