Description
This unit of competency is part of the Aeroskills Aircraft Armament Certificate IV training pathway. It covers the competencies required to maintain aircraft egress systems that contain explosive ordnance.This unit was developed from PUADEFEO717C Maintain aircraft egress systems and is equivalent to that unit. This unit is used in workplaces that operate under the airworthiness regulatory systems of the ADF and CASA.

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 aircraft egress systems and system components 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 egress system maintenance activities. It is essential that assessment confirms the ability to comply with organisational safety requirements and appropriate legislative and regulatory requirements while maintaining aircraft egress systems. The ability to work safely within an explosive ordnance environment, conduct applicable tests and maintain relevant documentation is critical.
Evidence of transferability of skills and knowledge related to egress system maintenance is essential. This is to be established through demonstration of the ability to:
render the system safe
perform relevant inspections and tests, replace components (including disarming and re-arming the system)
perform appropriate maintenance tasks.
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 a range of tasks that is representative of the maintenance tasks, tests and the range of non-explosive and explosive components listed in the Range Statement. 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.
Access will also be required to facilities and resources used in the storage, distribution or maintenance of explosive ordnance, including a licensed explosive site.
