Evidence Required

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 install and remove restraint systems 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 restraint system inspection procedures cleanliness requirements repair procedures and safety precautions are fully observed understood and complied with Ability to interpret maintenance installation and removal procedures and apply them in practice is critical Evidence of transferability of skills and knowledge related to restraint system maintenance installation and removal is essential This is to be demonstrated through demonstration of the ability to recognise faults replace components and perform appropriate repairs that are within the bounds of the individuals authority and through the demonstration of correct installation and removal 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 inspection repair installation and removal of restraint systems including the demonstration of the ability to recognise a range of faults and their serviceability and repair limitationstolerances must include verification of expiry dates of restraint system component parts and recognition of incorrect manufacture 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
