SUBJECT:
Sloshing Compound A
Kitfox™ owner reported recently that the sloshing compound in his
aluminum header tank detached and clogged the fuel line. He landed
without incident but of course fuel starvation can have serious
consequences. The
following action must be taken if you have a header tank or wing
tank: HEADER
TANK - Remove and drain
the header tank. Slosh the tank with 8 ounces of MEK to remove the
sloshing compound. Test the tank for leaks by pressurizing it with air
to a maximum of 04 lbs. p.s.i., and soap the seams. If it does not leak,
install the tank. If it does leak, repair the leak or send it to Denney
Aerocraft Company and we will repair it or replace it. WING
TANK - Drain the tank
and inspect it through the filler neck with a flashlight and mirror. If
the sloshing compound is intact no further action is required. You
should inspect your wing tank regularly, every 10 hours. If the sloshing
compound has begun to flake away from the tank wall, you will have to
slosh the tank with MEK to remove the compound. You may accomplish this
by removing the wing with the tank intact. Then you can rotate and shake
the wing well enough to slosh the MEK on all the surfaces of the tank. If
the tank leaks when the compound is removed you will have to remove the
wing tank. Denney Aerocraft Company will replace any defective tank. Be
careful when using MEK as it will soften and dissolve stits Poly-tak,
Poly-brush and Poly-tone. If
you need assistance in any way, please call customer service. Before
returning any items to Denney Aerocraft Co.
please obtain a Return Goods Authorization (RMA) number from customer
service.
