Elements and Performance Criteria

1. Remove fixed wing flight control system components
   • System is rendered safe in accordance with the applicable maintenance manual and isolation tags are fitted, where necessary, to ensure personnel safety
   • Fixed wing flight control system component removal is carried out in accordance with the applicable maintenance manual while observing all relevant work health and safety (WHS) requirements
   • Required maintenance documentation is accurately completed and correctly processed
   • Removed components are tagged, sealed and packaged in accordance with specified procedures
2. Install fixed wing flight control system components
   • Components to be installed are checked to confirm correct part numbers, serviceability and modification status
   • Mass balance of control surfaces to be installed is checked in accordance with the applicable maintenance manual, if required
   • Installation is carried out in accordance with the applicable maintenance manual while observing all relevant WHS requirements
   • Required maintenance documentation is completed and processed in accordance with standard enterprise procedures

Range Statement

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

Performance Evidence

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:

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 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 Assessment Conditions.
