Just put the wings on for the last time with the close tolerance bolts at the airport. The top row of bolts are no problem. The bottom row of bolts are a piece of engineering nobody could be proud of. There are major interference issues with the gear leg support weldments that prevent getting a wrench on the nut to do anything other than stop the nut turning. You have to insert the bolts with just a couple of threads through, get the nut started, tap the bolt in, turn the nut a quarter turn, tap the bolt and repeat until there are enough threads into the nut that the bolt can be drawn in by turning the bolt. I cooled the bolts down in the freezer overnight before inserting them in the spar fitting (with grease) but even so the bolt turning friction was significant so I don’t have a good feel for what final torque I have on the bottom bolts. More of an issue for the AN4 size bolts. Having this poor quality of engineering in such a critical area just beggers belief. I am really surprised that there hasn't been more calls for Vans to fix the design in this area. This may get a pass grade from a FEA viewpoint but is totally unacceptable from an assembly and maintenance viewpoint.
