Stab/Wing questions

Peaks of skin creases always go out.

Chromate all joints outside the tank, just proseal if inside the tank and
exposed to fuel. However it won't hurt to proseal additional places it just
doesn't seem worth the trouble and expense when the joints are already
strong
enough and moisture proof.

Yes you drill for more rivets in the other hinge doubler plates as well but
you
may want to wait until after the torque tube mounts are installed so you can
see
where those rivets go and avoid interference.

All,

I have a couple of quesitons regarding the stab and wing assemblies.

1. On the stab assembly, it mentions placing the crease in the skins
down
at first (I think) and then later turning them over but never mentions it
again. What direction should the creases in the stab skin face upon final
assembly?

2. Wing construction
a. chapter 10.2 step 14 it says to proseal between W138 and
mainspar.
Do you chromate W137 and cap or is it beneficial to proseal these as well.

b. 10.4 step 14. Do you drill our the rest of hinge backing plate
(middle one) the same as the outboard backing plate? figure 10.4.3 the
diagram only shows making 2 rows of rivets kind of like this
Backing plate
