Overview of assessment

A person who demonstrates competency in this unit must be able to test and troubleshoot a range of hydraulic fuel gaseous and mechanical system and landing gear components in accordance with relevant maintenance manual instructions while applying all relevant OHS procedures and standard processes

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 testing and troubleshooting applications including the timely involvement of supervisors or other trades associated with aircraft hydromechanical gaseous mechanical and landing gear systems and their components It is essential that system test procedures take into account all safety precautions applicable to the system being maintained especially where system operationswitching interrelates to other systems being maintained Ability to interpret inspection procedures and specifications allowable limits and apply them in practice is critical

Evidence of transferability of skills and knowledge related to testing and troubleshooting is essential This may be demonstrated through application across a number of aircraft systems or aircraft types The application of testing procedures should clearly indicate knowledge of system operation the relationship of individual components and the links with other systems if applicable within the limits of the aircraftsystem fault finding guide before undertaking any action 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 this unit of competency are being achieved under routine supervision on each type of system and on at least one component of each group listed in the Range Statement as follows

Hydraulic systems a system and at least one component from each of hydromechanical system components and

Fuel systems a system and at least one component from each of and

Landing gear systems each listed system to

Landing gear components one each of to

Gaseous systems each listed system to and at least one component from each of gaseous system components to

Mechanical systems a system applicable to and at least one component from each of mechanical system components and

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 work environment or simulated work environment using procedures tools and equipment specified in maintenance documentation It is also expected that general purpose tools test and ground support equipment found in most routine situations would be used where appropriate The level of troubleshooting is limited in its application to the use of fault diagnosis guides or other similar information

Method of assessment
