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 maintain and pack survival inflatable life rafts and escape slides while observing 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 life support equipment maintenance activities. It is essential that survival inflatable device testing and inspection procedures, cleanliness requirements and safety precautions are fully observed, understood and complied with. Ability to interpret maintenance and packing procedures and apply them in practice is critical.

Evidence of transferability of skills and knowledge related to survival inflatable life raft and escape slide maintenance and packing is essential. This is to be demonstrated through demonstration of the ability to recognise faults and replace components that are within the bounds of the individual's authority, and through the demonstration of correct packing procedures. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.

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 the following range of tasks:

• completing a minimum of three (3) inflation tests without the need for corrective action by the supervisor
• recognising the limits of own authority
• testing cylinder weight and determining if it is within tolerance
• correctly packing a minimum of three (3) survival inflatable life rafts or escape slides without the need for corrective action by the supervisor
• recognising a range of faults and their serviceability limits (faults must include incorrect manufacture and verifying expiry date of inflatable life raft and ancillary equipment or escape slide.

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 workplace or simulated workplace using materials, tools and equipment specified in the maintenance manuals and applicable procedures. It is also expected that general and special purpose tools and ground support equipment would be used where appropriate.
