          • applying relevant WHS practices, including lifting and handling heavy components




          • using relevant maintenance documentation and aircraft manuals to:




          correctly remove and install main rotors and rotor heads




          check the mass balance of rotor blades and heads




          correctly remove and install tail rotor blades and pitch control assemblies




          locate and correctly remove and install mechanical flight control system components




          locate and correctly remove and install drive train components, such as gearboxes and drive shafts and couplings




          identify the requirements for component balancing




          • identifying the requirements for adjustment and rigging of systems after componentremoval and installation.




          It is crucial that safety precautions related to the rotary wing rotor and flight controlsystem components being maintained, including allowance for the effect on weight andbalance (i.e. centre of gravity) when heavy components are removed, are fully perceived,understood and complied with.




          Transferability evidence of skills and knowledge related to removal and installation isimportant.This may be demonstrated through removal and installation of a representativerange of the rotary wing rotor and flight control system components as specified in theAssessment Conditions.




(b) Knowledge Evidence




          Evidence required to express competency in this unit must be related to and fulfil allof the requirements of the elements and performance criteria and include knowledge of:




          • component attachment methods




          • removal and installation procedures for:




          main rotors and rotor blades




          rotor heads




          tail rotors and tail rotor blades




          swash plates




          • tail rotor pitch control assemblies




          • requirements for the checking and adjustment of blade tracking after rotor maintenance




          • control system layout, linkages and operation (operation only to the extent necessary for the specified tasks), including the requirement for rigging and the independent inspection of work performed




          • power train layout and assembly:




          main rotor gearboxes




          intermediate gearboxes




          tail rotor gearboxes




          drive shafts




          couplings




          • relevant WHS practices, including those relating to lifting and handling of heavy items




          • relevant maintenance manuals




          • relevant regulatory requirements and standard procedures.

18. รายละเอียดกระบวนการและวิธีการประเมิน (Assessment Description and Procedure)


          • The assessment are composed of paper exams , interviews, and practical demonstrations, which the paper exam is the main testing. The selection of interviews and practical demonstrations are depending on the assessors’ judgment.




          • Competency should be assessed in the work environment or simulated work environment using tools and equipment stated in aircraft maintenance manuals. It is also expected that applicable general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate




          • Before undertaking any action,an understanding of component attachment methods, the need for adjustment or rigging and system operation as it relates to the work must be demonstrated. The work plan should consider applicable safety and quality requirements according to 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 and performance criteria of the unit of competency are being achieved under routine supervision on at least one (1) item from each of the following groups:




          main rotor blades and tail rotor blades




          rotor heads




          swash plates, tail rotor pitch control assemblies




          mechanical flight control components (i.e. cables, pulleys, guides, fairleads, tension regulators, control rods, bellcranks, torque tubes, control sticks or columns, tail rotor pedals) and mechanical components of powered flight control systems




          main rotor, intermediate or tail rotor gearboxes




          drive shafts and couplings.This shall be proven via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.




          • Individuals being assessed who have already attained 102303 Maintain basic rotarywing aircraft systems will have satisfied the requirements of this unit with regard tocommon Range Statement variables. The Log of Industrial Experience and Achievementrecords relating to 102303 Maintain basic rotary wing aircraft systems may be acceptedas also meeting the evidence requirements for this unit in the applicable common areas.
