| Subject: | Firestar I question |
I'm getting the Firestar ready for its certification inspection and I'm
curious about the leading edge tubes that stick out of the wing root about a
foot. Any idea what they do? I'd just as soon cut them off and plug them,
but not if they actually have a purpose. TIA.

Rick, The only thing I can think of, is that it help`s the fabric gap seal
keep it`s shape. Also. I tie mine together to help keep the wings steady
when I trailer to the airport. I don`t know if there is any other reason or
not. Lanny N598LF

Rick,
I find the tube extensions useful when folding and unfolding the wings.
I trailer my plane each time it is used and use a tripod to support the
unfolded wing prior to inserting the pins. The tripod supports the
outer end of the wing and the tube extension supports the front edge of
the wing by resting on the top of the full enclosure. Makes the folding
and unfolding a one-man job. Also, the extension is used in the folded
plane to tie the wings together.

| Subject: | Rotten cage tubes found. Photos attached. |
Today I was cleaning up the cage getting it ready to start painting it with primer.
I found a rotted tube. It wasn't noticeable until I started wiping it
down with a scrubbing pad. You can see it is wet inside the tube.
I had to test the other tubes as well and I didn't know how best to do it. What
I did was I took a piece of aluminum tubing and started hitting the other tubes.
When I came to the spot in the other side of the cage I left a dent so I know
that side was weak as well. I guess that is a good way to test your tubing
even if it is covered.
It was good to find it now rather then while landing.
So now I have two tubes that need to be replaced. Does anyone know what size and
type of tubing I will need? I plan on bringing it to an aircraft repair shop
but I would like to know the size in case I need to provide my own material.

Hi Scott,
One method to use to inspect tubing for integrity is to use an awl or sharp pick
and apply firm hand pressure with the point of the tool to the tube in question.
If the awl or pick penetrates the tube or deforms it, you have a corroded tube.
I would very carefully inspect all the lower tubes for corrosion as you may have
other tubes that are in bad shape.
You will have to call Travis at Kolb to find out the wall thickness of the tubes
that are damaged. The construction plans for my Firestar II do not specify
tube wall thickness.

I've seen Kolbs both with and without the extensions. My Ultrastar has the
extensions, and there's another section of tubing that slips over them and
joins them together when the wings are unfolded. Whether that piece is
actually necessary I don't know, it should stiffen the wings a bit and it
also helps to support the fabric center gap seal (clear plastic, actually,
on mine). IIRC it's not shown that way on the drawings, though. I've
never flown the plane without it, but I figure it can't hurt.

Looks like the result of no drain holes in the fabric, if left out with inadequate
cover the moisture or rain settles in the low spot. Tube has to be replaced
so you could cut through it and mic the wall thickness before you take it to
be repaired. Aircraft Spruce will have what you need.

Those leading edge extensions are real handy if you fold and unfold regularly.if
you have the long windshield installed,the tubes rest on the "U" frame so you
can rest the tip of the wing on the ground and walk to the fuselage to install
the pin.With out them,you must support the wing leading edge as you work your
way to the cage to install the pins.The dihedral will not allow the extensions
to line up to tie them together easily.

My gap seal hooked to the tubes your talking about cutting off, if it wer me
I would take advantage of all the uses of them and not cut them off.
Holding wing in place while installing pins, and a good place to secure the
wings in a trailer, or on a open trailer, I use them to secure the wings when
I hauled it down the road tail first without a trailer, but its your plane
have fun trying to find another handy tool built in that makes life easier with
a Kolb or cut them off and come up with alternative ways to do what they can
do for you.
its your decision have fun with it

Hi Folks:
May have corroded from inside out.
Primary reason to use tube seal inside the fuselage and other 4130 tubes. Just
cause you can not see it, does not mean it ain't rusting away while you sleep
and fly.
The awl punch test will tell you when the tube is about ready to fail. Won't tell
you anything about a tube that is rusting from inside out and not reached
the point that the awl will penetrate the corroded tube.
I have been using one quart of Stitts Tube Seal for 24 years and three Kolb fuselages.
Still have a pint left. Never had a tube rust through, yet. ;-)
Ignoring it will not make it go away.

The Ultrastar is different, the extended tubes actually make it _more_
difficult to unfold the wings, since the pivot point is at the main spar
and not the rear... the rear fitting is its own support as you lift the
wingtips up. There's so little dihedral (if any) that slipping the splice
tube into place is no problem.
