NOTE: The instructions given in this Service Bulletin are only applicable to the
systems and parts installed at the time of delivery of the aircraft or as
changed by Bombardier Aerospace Service Bulletin(s).
(1) This modification is applicable to aircraft that have the COX & CO. 3043 Series
ribbon heaters installed through one of the following drawings:
NOTE: If water lines are not equipped with COX & CO. 3043 Series Ribbon
heater, no further action is required.
− Bombardier Drawing TM453071−XX “W/D EL Water Heaters”.
− Innotech Aviation Drawing WDBXXXX−XXX “W/D − Water Heaters, Galley
and Vanity”.
− Bombardier Drawing 6043070004 ”W/D − Water Line Heater System”.
− Bombardier Drawing 6043070005 “W/D − Water Line Heater System −
Small Lavatory”.
− Bombardier Drawing BAS6302XXXX “W/D Water Heater Modification”.
− Bombardier Drawing BAS6302XXXX “W/D − Ribbon Heater Installation
Modification”.
B. Reason
During a maintenance activity on a CL−604 aircraft, smoke was detected in the
AFT cabin (FS591). Materials surrounding the water line were burnt and damaged.
The probable cause was found to be a faulty drain line Cox & Co. ribbon heater
where circuit breaker CB2−D5 did not trip and the ribbon heater thermostat was
well functioning. The ribbon heater leads were not identified to verify proper
installation.

(3) Do an operational test of the water line heater system per applicable aircraft
specific SMM 38−10−00.
(4) If the SMM is not available, test the water line heater system in the steps that
follow per best shop practice:
(a) Press the AC/DC UTILITY switch. (Location of switch may vary on each
aircraft).
(b) Using a digital thermometer probe, touch a point on each ribbon heater
and note the measured temperature.
(c) Locate the thermostat on each ribbon heater, apply a coat of cooling agent
(freeze spray) to lower the temperature. Make sure the temperature is
below 40°F (4.4°C).
(d) The water line should warm up in a few minutes. Using a digital
thermometer probe touch the same point on each ribbon heater and note
that the measured temperature is higher than that measured in step (b).
CAUTION: MAKE SURE YOU DO NOT APPLY A TEMPERATURE MORE
THAN 122° F (50.0° C). YOU MAY CAUSE DAMAGE TO THE
EQUIPMENT.
(e) Apply heat to the thermostat on each ribbon heater and make sure that the
applied temperature is above 60°F (15.6°C).
(f) Remove the heat source.
(g) After a few minutes, using a digital thermometer probe, touch the same
point on each ribbon heater and note that the measured temperature is
lower than that taken in step (d).
(5) Make sure you repeat all applicable steps for each ribbon heater.
I. Close −Out
NOTE: The steps in the Close −out section of this Service Bulletin, except for the
return−to−service tests, are recommended steps. The steps give a
recommendation to install components removed during the Aircraft
Set−Up. This recommendation is to make sure that the aircraft is safe and
