(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 ofassessment, and must include:

• Applying relevant WHS practices.

• Using relevant maintenance documentation and aircraft manuals to:

• Remove flight control surfaces.

• check the mass balance of control surfaces, where required.

• Install flight control surfaces.

• Remove power flight control system components.

• Install power flight control system components.

• Remove mechanical flight control system components.

• Install mechanical flight control system components.

It is essential that safety precautions applicable to the fixed wing flight control system being maintained are fully observed, understood and complied with (especially flight control systeminter-relationships with other systems where applicable). An awareness of dual inspectionrequirements associated with work on flight controls and systems must also be demonstrated.Evidence of transferability of skills and knowledge related to removal and installation isessential. This may be demonstrated through removal and installation of a representativerange of the fixed wing flight control system components listed 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 knowledge of:

• Flight control surface and system component attachment methods.

• Connection hardware and couplings.

• Electrical circuit isolation and plug removal and installation.

• Requirements for balancing of control surfaces.

• Flight control system rigging requirements.

• Requirements for independent inspection of work performed on flight control systems and Components.

• Relevant WHS practices.

• 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 system

Components include:

• 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, rudder pedals).

Procedures and requirements include:

• Industry standard procedures specified by manufacturers,

regulatory authorities or the enterprise.

• The assessment are based on combination of paper exams, interviewing, and practical demonstrations depending on the assessors’ judgement.

• Competency should be assessed in the work environment or simulated work environmentusing tools and equipment specified in maintenance manuals. It is also expected thatgeneral-purpose tools, test and ground support equipment found in most routine situationswould be used where appropriate.

• An  understanding of component attachment methods and the need for adjustment orrigging and system operation as it relates to the work must be demonstrated beforeundertaking any action. The work plan should take account of applicable safety andquality requirements in accordance with the industry and regulatory standards.

• 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 from each of the following component groups:

ailerons, elevators, rudders, trim tabs, speed brakes, spoilers, flaps and slatsactuators – mechanical, hydraulic, pneumatic or electricmechanical flight control components (cables, pulleys, guides, fairleads, tensionregulators, control rods, bellcranks, torque tubes, chains, sprockets, control sticks,wheels or columns, trim wheels or handles, 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).
