SERVICE BULLETIN
CAB-30-02
WARNING:
For health and environmental data, review the Material Safety Data
Sheet (MSDS) for TKS fluid. Refer to the MSDS that should be
included with the shipment of TKS fluid. If you cannot locate the
MSDS, contact your supplier of the TKS fluid to obtain the MSDS.
WARNING:
Make sure that you use applicable eye protection when you work
near the ice protection system. The system uses high pressure
in the lines to operate correctly, and the fluid pressure stays in
the system lines until it is released. If you do not use applicable
eye protection, fluid under pressure can hit your eyes and cause
damage when you do work on the system.
WARNING:
Discard all unwanted TKS fluid and/or dirty cloths correctly. TKS
fluid is a hazardous waste and must be discarded in accordance
with procedures approved by the local jurisdiction.
(1)
Make sure that you wear applicable eye protection when you do work on or near the ice
protection system.
WARNING:
Before you disconnect components of the TKS anti-ice system,
slowly loosen the coupling that is connected to the component
to be removed because it is possible that high pressure is still
in the system.
(2)
Slowly loosen the connection at the necessary fitting to release high pressure in the system.
WARNING:
Make sure that you remove ice protection fluid from the floor
surfaces where passengers and personnel walk. The fluid can
make surfaces slick.
(3)
Remove all ice protection fluid from areas where people walk. Since there is leakage of fluid
from the panels for a while after the system is no longer in operation, make sure that you
collect fluid that drips from the airplane or continue to remove fluid from the floor until there
is no more leakage.
CAUTION:
Never use unapproved ice protection fluids in the ice protection system.
Never use a thickened anti-ice fluid or one that is made for use on the
runway, in automobiles, or on parked airplanes. If you use fluids that
do not meet the DTD 406B specification, you will do damage to the
membranes in the porous panels and other system components.
CAUTION:
Use only clean, filtered fluid in the TKS system. Contamination will cause
fluid blockage and/or damage to the porous panel.
(4)
Use only ice protection fluids that meet the DTD 406B specification in the ice protection system.
(5)
You can mix fluids that meet the DTD 406B specification in any proportions in the airplane tank.
CAUTION:
Do not do damage to the ice protection system with solvents or paints.
Most solvents and all paints can cause damage to the plastic membrane in
the porous panels. Use only the materials from the list below when you
work on or near the porous panels. Never use MEK, acetone, or lacquer
thinner. Always use masking material when you use paint or solvents that
are not on the list below when you work on or near the porous panels.
(6)
The materials that follow are approved to clean the porous panels. Use them with a brush or a
lint-free cloth:
•
Water with soaps or detergents
•
Aviation gasoline
•
Isopropyl alcohol
•
Industrial methylated spirit
•
Ice-protection fluids that are approved for use on the airplane
•
Aviation turbine fuel
