Sounds like the bottom line is that the horizontal stab ends up parallel to
the top longerons, no positive or negative incidence, correct?

--> Pietenpol-List message posted by: "baileys" <baileys@ktis.net>
According to the System Three Literature the upper service limit of T-88 is
160 degrees F. I would guess that the internal temperature of a dark
colored wing could exceed this especially when sitting still on the ground
in the summer time. Has anyone experienced (or heard of ) the adhesive
failing due to heat?
Just wondering,

I downloaded the wonderful pics DJ Vegh took of his "flop". We're putting a
"flop" on our GN1 Aircamper, and want to know what AN latches are. Apparently
they are used to lock the flop in the down position. Where can I purchase AN
latches? Thanks, Jim Cooper

I used Aircraft Spruce part number
TL800G Latch
TL800-5 Strike
I can provide some detailed pics of the latches installed if you'd like

also... the actual name is DZUS latches... I have no idea why I called them AN
latches... They are not an AN part number. I need to make that change on my
website.

Good question. I have never heard of any failures, but always wondered about
that, myself.

I went through this concern as well as my understanding
was that it lost 1/2 it's strength at that temp.
From their site- lap shear strength in maple-1800 psi.
The wood let go. Doesn't tell us anything.
Tensile strength of the film-7000 psi.Variation with
temp on glued aluminum; 2500 psi @ 67 to 1000
psi @ 180 F. That's shear strength again but is that the
shear strength of the glue? or simply the adhesion limit
on aluminum?
Shear strength for spruce is 1120 psi. So it appears
that at 160 or so it would be a tossup as to which
would let go, wood or glue. Up to that point the joint
is going to be the same strength. Above it the glue
becomes progressively weaker than the wood so it
depends on what the specific load is on that joint. If it
never sees more than 500 psi then it will do it's job until
the glue weakens below that figure, at an even higher temp.
What's the smallest gusset in the fuselage and where is it?
If it was 5 square inches then the shear strength would be
5600 lb. If that joint will never see 1000 lb then it will
probably be good at very high temps. If it sees 3000 lb
then the failure temp will be lower but may still be well above
anything that joint will experience.
That's the way it looks to me anyway.
Does it appear reasonable to you guys?
