Application
This unit of competency is applicable to all Aeroskills maintenance training pathways. It requires application of basic hand skills and standard trade practices in the maintenance of aircraft and aircraft components.
The competency applies to the selection and use of hand and power tools and equipment associated with scheduled and unscheduled on-aircraft or workshop-related activities in the aircraft maintenance environment that involve:
laying out and fabricating simple items from common aircraft materials
assembling items using a representative range of common types of aircraft attachment hardware for which relevant fits and clearances, appropriate safety locking devices and fasteners, including lockwire, are correctly selected and applied
assembling/connecting a range of common aircraft connectors and plumbing, applying safety locking devices, where applicable
assembling/connecting aircraft control cables and applying safety locking devices, where applicable
the use of lubrication equipment and lubricants.
Work may be performed individually or as part of a team and in accordance with industry standard procedures specified by manufacturers, regulatory authorities or the enterprise.
The unit is used in workplaces that operate under the airworthiness regulatory systems of the Australian Defence Force (ADF) and the Civil Aviation Safety Authority (CASA).
Where a CASA licensing outcome is sought this unit forms part of the CASA requirement for the granting of the chosen maintenance certification licence under Civil Aviation Safety Regulation (CASR) Part 66, in accordance with the licensing provisions in the Companion Volume Implementation Guide.

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:
the correct identification, inspection of, application, use and storage of general and purpose specific hand tools (i.e. spanners, screwdrivers, pliers, hammers, cutting devices, files, punches, drills and marking out tools) that may be found in an aircraft engineering workshop or hangar
the correct identification, inspection of (including calibration), application, use and storage of precision measuring tools (i.e. micrometers, vernier instruments, feeler gauges, go/no-go gauges) that may be found in an aircraft engineering workshop or hangar. Reading instrument scales must be clearly demonstrated during application of instruments to ensure compliance with specifications
the correct identification, inspection of, application, operation and storage/servicing of portable and fixed power and machine tools (i.e. drills, presses, grinders, shears, pan breaks) that may be found in an aircraft engineering workshop or hangar
identification, inspection and use of lubrication equipment
determination of correct lubricants for specified applications
identification of common ferrous and non-ferrous aircraft materials
identification of common aircraft composite and non-metallic materials (other than wood)
identification of aircraft hardware by markings, part numbers, size, shape and material
the installation of aircraft hardware using standard practices/techniques to ensure safe security and includes:
minimum thread engagement
split pinning
lockwiring
application of locking compounds
locking tabs, spring washers
lock nuts
the installation of aircraft hardware using tightening, torquing and tensioning techniques. Calculating setting, reading scales and setting up of torque wrench and/or tensioning devices must be clearly demonstrated before application of wrench or device
identification of various types of aircraft rigid and flexible plumbing and their connectors
identification of aircraft control cables and related cable system hardware
manufacture of simple items using basic hand skills.
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:
types of standard aircraft hardware and methods of identification, including bolts, nuts, washers, pins (cotter, tapered) and fasteners (rivets and camlocs)
materials from which hardware is manufactured and its applications, including plain, corrosion resistant and temperature/heat resistant
types of safety locking devices and their application
common ferrous and non-ferrous aircraft materials, heat treatment and testing
characteristics and properties of common composite and non-metallic materials other than wood
types of aircraft cable, turnbuckles, end fittings, tensiometers, pulleys and cable system components, and aircraft flexible control systems
types and characteristics of lubricants
types and uses of lubrication equipment
fits and clearances
laying out of simple items for manufacture using basic hand skills
hand and power tool storage and maintenance requirements
tool calibration requirements
WHS requirements relevant to the use of hand and power tools.
Assessment Conditions
Competency should be assessed in the work environment, or by use of simulated activities, using tools and equipment specified by aircraft manuals as well as general purpose tools and test equipment found in most routine situations.
This unit must be linked in its assessment and application to those units that apply to actual maintenance of aircraft. It is essential that all WHS requirements are met and understood.
Evidence of knowledge about how tools and equipment are selected, used and maintained is essential. The ability to manipulate tools and equipment correctly in the performance of tasks is necessary to demonstrate transferability of hand skills across a variety of applications.
The following conditions of assessment represent the requirements of the Regulators (ADF and 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 the unit of competency are being achieved under routine supervision on the following tasks:
laying out and fabricating simple items from common aircraft materials
assembling items using a representative range of common types of aircraft attachment hardware for which relevant fits and clearances, appropriate safety locking devices and fasteners, including lockwire, and applicable lubricants are correctly selected and applied
assembling/connecting a range of common aircraft connectors and plumbing, applying safety locking devices, where applicable
assembling/connecting aircraft control cables and applying safety locking devices, where applicable.
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 Implementation Guide).
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.
