Task: Sealed and riveted the right fuel tank
inboard and outboard ribs
we sealed and riveted the inboard and outboard ribs on the
right fuel tank. I first riveted the T-410 to the outboard
end rib. We then flared and fit the vent line, applied sealant
to the tank skin, clecod the end ribs in place, and then began
riveting the inboard rib. Then we secured and sealed the flop
tube and reinforcement brackets. After the outboard end rib
was riveted in place, we torqued the vent line fitting and
put a dab of ProSeal on each snap-bushing to prevent anything
The ProSeal applicator. A very nice thing to have! We got
away with a home caulking gun until finding a fellow RV builder
with the right tool. Makes much less of a mess!
is the inboard end rib. The vent line elbow AN4 fitting was
already toqued and sealed last week. We hand squeezed all
of these rivets and then drove the AN470 rivets that join
the T-405 and T-410 reinforcement plates.
we inserted and torqued the flop tube to 120 in. lbs and sealed
the heck out of it!
Last we squeezed
all the rivets in the outboard end rib and make a nice fillet
and covered the shop heads with ProSeal.
