By following a diagram, the fitting operator must identify the elements to assemble, rigorously check the various components and finally, carefully mount these ends on the connecting rods. There are 3 mounting types: adjustable (the rod will then be adjusted on aircraft), fixed (the rod is fixed in a precise configuration), and mechanical (more complex because this requires the assembly of several parts and therefore more adjustments). His role is to ensure that the finished rod is functional (no defect, shock, and verification of marking ...), but that it is also visually esthetic (no trace of paint, fingerprints ...).
The fitting operator works at the end of the process and in self-check mode, so he is the guarantor of the compliance of the components manufactured upstream.
