- Swage fittings onto cables, using swaging machines.
- Manually install structural assemblies or signal crane operators to position assemblies for joining.
- Set up or operate machines or systems to crimp, cut, bend, form, swage, flare, bead, burr, or straighten tubing, according to specifications.
- Place and connect control cables to electronically controlled units, using hand tools, ring locks, cotter keys, threaded connectors, turnbuckles, or related devices.
- Install mechanical linkages and actuators, using tensiometers to verify tension of cables.
- Clean aircraft structures, parts, or components, using aqueous, semi-aqueous, aliphatic hydrocarbon, or organic solvent cleaning products or techniques to reduce carbon or other harmful emissions.
- Install accessories in swaging machines, using hand tools.
- Mark identifying information on tubing or cable assemblies, using etching devices, labels, rubber stamps, or other methods.
- Verify dimensions of cable assemblies or positions of fittings, using measuring instruments.
- Weld tubing and fittings or solder cable ends, using tack welders, induction brazing chambers, or other equipment.
- Splice cables, using clamps and fittings, or reweave cable strands.
- Fit and fasten sheet metal coverings to surface areas or other sections of aircraft prior to welding or riveting.
- Capture or segregate waste material, such as aluminum swarf, machine cutting fluid, or solvents, for recycling or environmentally responsible disposal.
- Cut cables and tubing, using master templates, measuring instruments, and cable cutters or saws.
- Monitor robotic assembly equipment, such as snake-arm robots, used to assemble, seal, or swage aircraft structures.
- Align, fit, assemble, connect, or install system components, using jigs, fixtures, measuring instruments, hand tools, or power tools.
