Here's a question to the aircraft designers here. What sort of tolerances are you designing your parts with? I know that some components require very tight tolerances, but what about stuff like rivet and bolt holes and positioning of brackets and hinge points. I'm familiar with tolerances (and tolerance stacking.) I work as a QC inspector in the oilfield and we deal with tolerances ranging from .0005 in. (very rare, thankfully) to .002 in., to block tolerances of .100 in. (+/-.015 is the most common). Or you might get pipe with API tolerances of +/- 6 inches.
