Good morning Cyrus,
There are two versions of aircraft tank sealant we use:
FlameMaster Chemseal CS3204-A-1/2
FlameMaster Chemseal CS3204-B-1/2
Both of these sealants come as a two-part mixture.
The Class "A" sealant is a pourable/brushable liquid used for getting
the tight tight areas.
The Class "B" sealant is the consistency of snot...and sticks like it too.
We use it to re-enforce the seam areas and on the access panels.
The "1/2" is the working time in hours- so be ready to seal when you mix it.
The Cure time is 30hrs.
We purchase these from Aviall 1-800-284-2551.
Your options are a "Semkit" which a pre-portioned tube or in Qt cans
which must be mixed 10:1 *by weight* (critical) RTFI
Clean surfaces are also critical.
Get a can of Toluene as it's the *only* substance which will clean the
stuff off.
As for the vent...I would separate the vent lines and run a new vent
line from the Aux Tank.
We simply go up and over the wing in the wing root. Which is plenty.
If you're seriously worried about porting fuel overboard, Andair
manufacters the best vent line check valve in the world (expect to pay
for it tho').
In regards to our system, we simply ran out 6 bays, we can go further
(and probably will) on the next system. We won't get the same volume as
Vytas because they actually remove the wing skin completely, and seal up
the wing back past the false spar- we simply seal back to it.
We decided that a system which added 1 to 2 hrs of flight time for 6-7k
was definitely marketable.
Our experience with the 52TW has shown that very few people actually
utilize the 4.5hrs leg the aircraft offers. A 2-3 hr leg dramatically
changes the utility of the aircraft.
I guess I'll need to re-read the posting instructions for the list as
the pictures I attached didn't come through <grin>
Best regards,
Cliff

Cliff,
I had Anabaras in Lithuania do a wet wing mod for me when they did my
plane. It leaked like hell form the day I got it to the point where I
simply disconnected it. Liutauras at Anabaras would not even email me
back. They also simply ran a vent line from the main aluminum tank
about 3/4 of the way up into the new wet wing. Fuel would leak into
the wet wing when the main was full and leak out.
Do you have any type of liquid sealer that you can recommend and a
method to apply it? Thanks,
Cy Kissling Stuart Fl
