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.
following action must be taken if you have a header tank or wing tank:
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.
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.
the tank leaks when the compound is removed you will have to remove the wing
tank. Denney Aerocraft Company will replace any defective tank.
