Hi Guys,
can't seem to find this in the instructions or drawings so maybe I'm just blind as a bat. On the top and bottom flanges of the wing ribs at the forward end there are two holes that attach the rib flange to the spar flange. One hole is captured by the wing skin. On the outboard leading edge the leading edge skin captures the other hole. However, the tank attaches to the spar with screws; what about those other holes. I'm sure I'm missing something on a drawing somewhere but I can't seem to find it. Countersink the spar and throw an AN426 rivet in there that goes under the tank skin? Or do they just get left?
I'm not at that point yet, as I'm rivetting the leading edge together at the moment and then I'll be fitting the leading edge light, but just glanced up at the spar on the jig and had one of those 'wait a minute...' moments.
Thanks,
