Elements and Performance Criteria

Application of this unit may relate to:
Scheduled or unscheduled maintenance
Individual or team related activities
Procedures and requirements refer to industry standard procedures specified by manufacturers, regulatory authorities or the enterprise.


1. Ailerons, elevators, rudders, trim tabs, speed brakes, spoilers, flaps and slats
2. Actuators - mechanical, hydraulic, pneumatic or electric
3. 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)

Overview of assessment
A person who demonstrates competency in this unit must be able to apply hand skills and use maintenance publications to remove and install fixed wing aircraft flight control system components while applying all relevant safety precautions.

Critical aspects for assessment and evidence required to demonstrate competency in this unit
The underlying skills inherent in this unit should be transferable into other units that require similar techniques. 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 system inter-relationships with other systems where applicable). An awareness of dual inspection requirements associated with work on flight controls and systems must also be demonstrated.
Evidence of transferability of skills and knowledge related to removal and installation is essential. This may be demonstrated through removal and installation of a representative range of the fixed wing flight control system components listed in the Range Statement. An understanding of component attachment methods and the need for adjustment or rigging and 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.
A person cannot be assessed as competent until it can be demonstrated to the satisfaction of the workplace assessor that the relevant elements of the Unit of Competency are being achieved under routine supervision on at least one item from each of Groups 1 to 3 listed in the Range Statement. This shall be established via the records in the Log of Industrial Experience and Achievement or, where appropriate, an equivalent Industry Evidence Guide.

Context of and specific resources for assessment
Competency should be assessed in the work environment or simulated work environment using tools and equipment specified in maintenance manuals. It is also expected that general-purpose tools, test and ground support equipment found in most routine situations would be used where appropriate.
