Considering the absence of anomalies in materials or construction of the examined wing spars from N106ER and N104ER, the disparity between the failure time of the accident wing spar and the inspection threshold time in the SB likely derives from the differences between normal. For example, if 16 positions are used to manufacture an aircraft, the 16th position would be the beginning of assembly, starting with either the nose section or wing spar buildups, and the 1st position would entail the installation of the engines and nacelle assemblies (the "nacelle" is the streamlined body which houses the engine). This last point requires the building of a special testing equipment which is able to generate a load compared to the one applied in flight. Wing Spars Starting at $20.
