The intent of this Service Bulletin was met on the aircraft that follow with the Service Requests for Product Support Action (SRPSA) listed in the table that follows:

AIRCRAFT SERIAL NO. SRPSA NO.

9489 000575841 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 Aviation Service Bulletin(s).

B. Reason

1. Condition:

Sensing elements delivered by Kidde to LTS are not able to properly detect leakages according to the temperature defined in the specification. Some of the Leak Detection Loop (LDL) elements supplied by Kidde may be non−conforming and these elements present a risk due to the inability to detect a bleed air leak.

2. Evidence:

ATP software used by Kidde to test the LDL elements has certain deficiency within the test equipment which result to a probability of having certain non−complaint LDL elements delivered to Bombardier.

3. Objective/Benefit:

This Service Bulletin introduces a procedure to test the serviceability (examine the functionality) on each LDL element installed on the aircraft and to replace those that have failed.

C. Description This Service Bulletin gives instructions to:

− Gain access to the equipment bay, − Gain access under the baggage bay, − Remove the belly fairings, − Gain access to the left wing root, − Gain access to the right wing root, − Do the heat gun temperature verification, − Do the flight compartment setup, − Do the test procedure at each location, − Fill out Appendix A with test results, and − Replace defective LDL element if needed.

B. Heat Gun Temperature Verification WARNING: THE LEAK DETECTION LOOP ELEMENTS MUST NOT BE EXPOSED TO DC VOLTAGES/CURRENTS.

WARNING: HEAT GUN SHOULD NOT BE USED NEAR FLAMMABLE LIQUIDS

OR IN AN EXPLOSIVE ENVIRONMENT (FUMES, GASES OR DUST). REMOVE MATERIALS OR DEBRIS THAT MAY BECOME IGNITED FROM WORK AREA.

WARNING: DO NOT LEAVE TOOL UNATTENDED WHILE RUNNING OR COOLING DOWN. OTHERWISE RISK OF FIRE.

CAUTION: DO NOT USE A METER THAT APPLIES A DC VOLTAGE. DO NOT USE INSULATION RESISTANCE “MEGGER” TESTERS OR DIELECTRIC VOLTAGE “HYPOT” TESTERS. THESE WILL DAMAGE THE LEAK DETECTION LOOP ELEMENTS.

CAUTION: WHEN HEATING LEAK DETECTION LOOP ELEMENTS, THE HEAT

GUN SHALL BE POSITIONED SUCH THAT THE HEAT IS NOT APPLIED WITHIN 1 INCH (2.5 CM) OF LEAK DETECTION LOOP ELEMENT WHITE GROMMETS.

CAUTION: DO NOT DIRECT HEAT GUN AIRSTREAM AT CLOTHING, HAIR OR OTHER BODY PARTS.

CAUTION: ALWAYS HOLD HEAT GUN BY PLASTIC ENCLOSURE. THE METAL NOZZLE REQUIRES APPROXIMATELY 20 MINUTES TO COOL TO WHERE IT CAN BE TOUCHED. DO NOT TOUCH NOZZLE OR ACCESSORY TIPS UNTIL COOL.

CAUTION: DO NOT STORE HEAT GUN UNTIL NOZZLE HAS COOLED TO ROOM TEMPERATURE. PLACE TOOL IN A CLEAR AREA AWAY FROM COMBUSTIBLE MATERIALS WHILE COOLING.

CAUTION: DO NOT CUT OFF HEAT GUN AIRFLOW BY PLACING NOZZLE TOO CLOSE TO WORK PIECE. KEEP INTAKE VENTS CLEAN AND CLEAR OF OBSTRUCTIONS.

CAUTION: USE SHIELD MATERIALS AROUND THE HEATED AREA TO PREVENT DAMAGE OR FIRE.

MODEL BD−700−1A11 (BD−700) Basic Issue: Dec 23/2022 700−36−5002 Page 8 of 50

CAUTION: PLACE TOOL ON A LEVEL SURFACE WHEN TOOL IS NOT HANDHELD. PLACE CORD IN A POSITION THAT WON'T CAUSE TIPPING. KEEP A FULLY CHARGED FIRE EXTINGUISHER NEARBY.

NOTES: 1. Testing to be performed in a hangar (well ventilated) or tarmac conditions with no precipitation.

2. Do not perform this test procedure when the ambient temperature is below 0°C (32°F).

3. Minimum manpower requirement is two (2). However, a third person may be required to assist with heat gun operation.

4. To ensure that the heat gun temperature is consistent during all testing, this verification procedure shall be performed prior to testing the first sensing element of each alarm set point and repeated after every 4 hours of testing or when the sensing element set point changes or when the ambient conditions in the test location change but not less than once per shift.

(1) The heat gun nozzle deflector shall be securely attached to the heat gun as shown in Figure 1 and Figure 3.
