(a) Performance Evidence

          Evidence required to demonstrate competency in this unit must be relevant to and satisfy allof the requirements of the elements and performance criteria under the specified conditions of

assessment, and must include:

          • applying relevant WHS procedures

          • using relevant maintenance documentation and aircraft manuals to:

          • recognise defects during visual inspection of fixed wing flight control systems andsystem components

          • rig fixed wing flight control systemsfunctionally test the operation of fixed wing flight control systems and recognise

          system/component malfunction or evidence of incorrect riggingto the extent permitted by applicable fault diagnosis guides, troubleshooting

          unserviceabilities in fixed wing flight control systems and clearly recording the causes of the unserviceabilities.

          The underlying skills inherent in this unit should be transferable across a range of inspection,testing and troubleshooting applications (including the timely involvement of supervisors orother trades) associated with the aircraft fixed wing flight systems. It is essential that testingprocedures take into account all safety precautions associated with flight control systemoperation, in particular where system operation/switching interrelates to other systems beingaintained, and that an awareness be demonstrated of dual inspection requirements associatedwith work on flight controls and systems.

          Ability to interpret system performance specifications (allowable limits) and apply them in

          practice is critical and shall be demonstrated through application across the range of systemslisted in the Assessment Conditions.

(b) Knowledge Evidence

          Evidence required to demonstrate competency in this unit must be relevant to and satisfy allof the requirements of the elements and performance criteria and include basic knowledge of:

          WHS precautions relevant to flight control system maintenance

          standard trade practices relating to tool and test/rigging equipment usage and

          installation/securing of system components

          flight control system layout and operation:

          theory of flight:

          airflow

          conditions of flight

          lift and forces

          drag

          wings, tailplane and vertical stabiliser

          lift augmentation (flaps, slats and slots)

          aircraft control surfaces and their function (elevator, ailerons, rudder, elevons and trim tabs)

          spoilers and speed brakes

          flight control balancing and flutter

          stability and control and flight control rigging

          mechanical system layout and operation:

          cockpit controls

          cables and cable tensioning

          pulleys and fairleads

          bellcranks

          levers

          control surface horns

          screwjacks

          push/pull rods

          powered flight controls:

          system layout and operation

          component construction and operation

          electrical and instrument interfaces:

          flaps

          trim

          position indication

          flight control system maintenance procedures and troubleshooting methods

          flight control system interfaces with automatic pilot systems

          relevant maintenance manuals

          relevant regulatory requirements and standard procedures.

          This field allows for different work environments and conditions that may affect

          performance. Essential operating conditions that may be present (depending on the work

          situation, needs of the candidate, accessibility of the item, and local industry and regional contexts) are included.

          Flight control systems and

          system components include:

          Elevator, aileron and rudder primary flight controlsystems and associated trim systems

          Speed brake, spoiler, flap and high lift systems

          Ailerons, elevators, rudders, trim tabs, speed brakes,spoilers, flaps and slats

          • Actuators – mechanical, hydraulic, pneumatic or electric

          • Mechanical flight control components (cables, pulleys,guides, fairleads, tension regulators, control rods,bellcranks, torque tubes, chains, sprockets, control sticks,wheels or columns, trim wheels or handles, and rudderpedals)Procedures andrequirements include:

          • Industry standard procedures specified by manufacturers,regulatory authorities or the enterprise

          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 specified in aircraft maintenance manuals. It is also expectedthat applicable general-purpose tools, test and ground support equipment found in mostroutine situations would be used where appropriate.

          The application of ground testing procedures should clearly indicate basic knowledge of systemoperation, the relationship of individual components and the links with other systems (ifapplicable) within the limits of the aircraft/system 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.

          Assessment conditions must also provide for basic knowledge of dual inspection requirements

          to be demonstrated.

          A person cannot be assessed as competent until it can be demonstrated to the satisfactionof the workplace assessor that the relevant elements and performance criteria of the unit ofcompetency are being achieved under routine supervision on at least one (1) item fromeach of:

          elevator, aileron and rudder primary flight control systems and associated trim systems

          speed brake, spoiler, flap and high lift systems

          ailerons, elevators, rudders, trim tabs, speed brakes, spoilers, flaps and slats

          actuators – mechanical, hydraulic, pneumatic or electric

          mechanical flight control components (cables, pulleys, guides, fairleads, tensionregulators, control rods, bellcranks, torque tubes, chains, sprockets, control sticks,wheels or columns, trim wheels or handles, and rudder pedals).

          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).
