Page 9.13, steps 2-3 & page 9.14, steps 1 and 2

 

 

The last two steps of page 9-13 have you rivet the forward spar to the ribs of the elevators as well as riveting the skins to the forward spar. The instructions are very clear about not riveting the skin between the tips and the last and first rib. I was going along all happy with my hand squeezer when I realized I had done just what I was not supposed to have done. Thank goodness it was only a few rivets when I caught myself. I did not drill them out and thought to myself, let me see if this is an issue before removing them or if I can work around it. I had written in sharpie on the top and bottom skin, the problem was that I was sitting on my stool and could not see the top or bottom skins and was looking directly at the spar during the riveting process. 

 

After this page 9.14 looks a little daunting. There are lots of instructions that probably should be broken into a separate page. I was about finished but decided "just 2 more steps". Little did I know these two steps would take me over an hour! it is just 8 rivets...why so long?!?!?!? These two steps simply have you attach the root rib to the rear spar with AN426 rivets and the root rib to the the gusset with AN470 rivets. Easy- peasey??? NOT so much so!! Well first off, I discovered that I had bent the flange on one of the root ribs. So I removed the clecos and was able to re-bend the flange back no problems. However, on both the left side and the right side the holes did not want to align properly. There appeared to be a little induced bend with the rear spar. Maybe this was because of the fact that I had not driven the rivets on one end since I am awaiting the bucking bar. I was able to force the parts to align themselves and get the rivets put in; however, it was somewhat of a but kicking. The good news was I got to use my new inspection mirror. I probably should have inspected these before I put the clecos back on for the skins (these went on very easy so I know it is all aligned now).
