Performance Evidence

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 WHS practices relating to helmet maintenance processes, including the selection and correct use of PPE, where applicable

using MSDS

using applicable tools and maintenance documentation to:

solder helmet electronic/electrical components

test the operation of helmet electronic/electrical components

replace unserviceable components in accordance with approved procedures including hand sewing, the use of hazardous chemicals and adhesives and thermal oven operation

select and use appropriate helmet cleaning materials

correctly fit helmets to users

tying of knots, including:

reef knot

bowline

thumb knot

half hitch

cleaning and maintenance of equipment and tools

correctly disposing of hazardous waste.

The underlying skills inherent in this unit should be transferable across a range of aircraft life support equipment maintenance activities. It is essential that helmet testing and inspection procedures, cleanliness requirements and safety precautions, including the correct use of PPE, are fully observed, understood and complied with. Ability to interpret maintenance and fitting procedures and apply them in practice is critical.

This is to be demonstrated through demonstration of the ability to recognise faults and damage and perform appropriate repairs that are within the bounds of the individual’s authority, and through the demonstration of correct fitting procedures.
