Evidence of Performance
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 relevant WHS practices, including the use of MSDS and PPE
jacking of aircraft for landing gear component removal
using hand skills and tools to perform component removal and installation tasks
correctly installing and securing of aircraft hardware
inspecting and correctly installing of bearings
safe handling of heavy components
using maintenance publications to prepare the aircraft for component removal and installation and correct interpretation of removal and installation instructions
applying standard procedures.
The underlying skills inherent in this unit should be transferable into other units that require similar techniques. It is essential that system cleanliness requirements and safety precautions applicable to the system being maintained are fully observed, understood and complied with.
This shall be demonstrated through application across a number of aircraft systems or aircraft types, but must cover a sufficient range of tasks to demonstrate familiarity with attachment methods, connection hardware and couplings peculiar to each type of system, and of safe handling of heavy components.
Evidence of Knowledge
Evidence required to demonstrate competency in this unit must be relevant to and satisfy all of the requirements of the elements and performance criteria and include knowledge of:
standard trade practices relating to tool usage and installation/securing of aircraft hardware
how to locate and correctly remove and install components
how to locate and correctly remove and install items of emergency equipment
WHS procedures relating to component removal and installation and handling of heavy components
How to obtain PPE
How to obtain MSDS
relevant maintenance publications
relevant regulatory requirements and standard procedures.
Assessment Conditions
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 applicable general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.
An understanding of system operation as it relates to the work must be demonstrated before undertaking any action. The work plan should take account of applicable safety and quality requirements in accordance with the industry and regulatory standards.
The following conditions of assessment represent the requirements of CASA and maintenance stakeholders and must be rigorously observed.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements and performance criteria of this unit of competency are being achieved under supervision without intervention on at least one (1) component from each of the following groups:
main and nose wheel assemblies
brake units
toilet system components (excluding gate valves)
windscreen wiper blades
passenger and crew seats, seat belts and harnesses
internal doors (excluding any doors that form part of the pressure hull)
trim panels, linings, cabin equipment and consoles
applicable emergency equipment, such as life jackets, rafts, location transmitters/beacons.
This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide (for details refer to the Companion Volume Assessment Guidelines).
Assessors must satisfy the requirements of the National Vocational Education and Training Regulator (Australian Skills Quality Authority, or its successors).
Where the unit is to be used for CASA licensing purposes the Assessor must also meet the criteria specified in the CASR Part 147 Manual of Standards.
Foundation Skills
Foundation skills essential to performance are explicit in the performance criteria of this unit of competency.
