Is there an “acceptable “ gap allowable between F-712 bulkhead and WD-409 taliwheel bracket. There was no gap when I riveted F-712, WD409 , and F-711 together on my bench. When I clecoed the aft fuselage shins together a 1/16” gap appeared on the top of the aft bulkhead. I removed the bolts from F-711 and WD409, and drilled out keeper rivets on F-712 to try to put a shim between F-711and WD-409 but it’s too tight to get a shim in there. It looks like the gap aft is only on the top inch or so. When I tap on the aft bulkhead it’s hollow sounding for the first inch where WD-409 mounts then sounds solid. Will it suck in when the vertical stab is installed? Thanks
