Service Letter #15

SUBJECT:      Wing Tanks, WT-1R and WT-1L and Header Tank, IP-4.

TO:                 Kitfox™ Owners with Serial numbers #2 through #270

FROM:           Denney Aerocraft Company

There have been reported incidences of aluminum particles traveling from wing tanks to header tanks. We now apply sloshing compound to all wing tanks and header tanks. If in doubt you may visually inspect your tank; sloshing compound appears as a white coating on the inside of the aluminum tanks.

IF YOUR TANK(S) DO NOT HAVE THE COATING IT IS RECOMMENDED THAT YOU APPLY A FUEL RESISTANT SLOSHING COMPOUND TO THEM AFTER FLUSHING THEM OUT. YOU MAY APPLY THE SLOSHING COMPOUND TO INSTALLED WING TANKS BY REMOVING THE WING FROM THE AIRCRAFT.
