Rib J

Postby Johnwell » Mon Feb 20, 2017 3:36 pm

Still wondering, after reading manual, why I can't place Rib J BEFORE wing close out.... My thinking is a much better (open) access to Rib R and Rib J for laminating it up. I have the 'new' bracket style and steel landing gear. Anybody did this in this order or am I overlooking an important procedure that can't be done if Rib J is already in place when I close out the wing?

Thanks,
John

I've been researching this also. Having done the install after the wing was closed was a real pain. I dont see why we cannot re-arrange the layup schedule so you put in the outboard layups of the aft shear web and rib R with a false skin. Then you can do the inboard side and finally put in the gear. It just means you have to combine the Rib J install and the aft shear web attach plates procedure into one with careful planning on the layup schedule.

I'm in the process of re-writing how I'm going to do those layups so I dont have to try and combine the steps "on the fly". It will be several weeks before I have time to get it done.

I am approaching that step now and will start on Rib R first with layups and the 'false' skin and then onto Rib J in a similar fashion, then Rib I.
I asked several people and all agree that, especially Rib R is so much easier to re-enforce while the wing is open instead of doing this through access holes. Absolute worst case scenario would be removing J or I in case I overlooked something dramatic. Other than mounting gear and flap brackets I can't see any obstacles....so far :mrgreen:
