Afternoon all,
Am working through the Seat Rib Assembly (DWG65) and am just wondering when people joined the centre bottom skins? (F-826-1 and F-827-1)
The instructions say this:
"Dimple Countersink all #40 holes in the F-826-1 Right Center Bottom Skin and the F-827-1 Left Center Bottom Skin, which are common with holes in the Seat Rib Assembly. NOTE: Do not dimple countersink the fwd and aft most rows of holes that are not common with holes in any of the seat ribs (See “F-826-1 & F-827- 1 Center Bottom Skins”, DWG 65)." (My Bold)
The row of rivets that join the 2 skins aren't in common with the seat rid assembly in that they don't join to any seat ribs. So according to those instructions they should be left untouched. But I can't see, looking forward in the plans, where these 2 skins are joined.
It's the row of rivets circled in red on the attached plan. (DWG65)
Can someone point me in the direction of when this is done? or is it done now?
