THIS SERVICE BULLETIN IS SENT TO EACH OPERATOR. IF THE OPERATOR HAS LEASED AIRCRAFT, THIS SERVICE BULLETIN MUST BE SENT TO THE LESSEE. IF THE OPERATOR HAS SOLD AIRCRAFT OR TRANSFERRED SPARES IN THE LAST SIX MONTHS, THIS SERVICE BULLETIN MUST BE SENT TO THE NEW OWNER, UNLESS CONFIRMATION WAS RECEIVED THAT BOMBARDIER COMMERCIAL AIRCRAFT DIVISION HAS INCLUDED THE NEW OPERATOR ON THE DISTRIBUTION LIST.



### SUBJECT:

### NOTE : The instructions 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 service bulletin(s). Before you do this bulletin, examine all STC, STA or equivalent action changes to make sure this bulletin can be completed. NOTE : The procedure in this service bulletin was validated on aircraft with serial number 15001.
B. Reason 

### (1) Condition In the bleed leak detection system, if there is a hot air leak after the rupture of a high−pressure duct, the duct insulation shroud will not transmit the air correctly through the vent holes of the insulation. If a bleed air leak is not sensed by the bleed leak detection system and the hot air goes in the direction of the adjacent structure and/or system components, it can have an unwanted effect on structure and system components. (2) Evidence Reports have shown that some components and structural areas need protection from the flow of direct bleed air leak. (3) Objective/Benefit This service bulletin gives the procedure to install protective shields on the upper surface of the wing box and fuel components, and to change the bleed leak sensing elements in the wheel well and the overwing areas. This will prevent damage to the wing box structure and fuel components if a bleed air leak occurs. C. Description 

### Circuit breakers are opened. The overwing access panels and the wheel bins are removed. The bleed leak sensing elements located in the MLG and the overwing are removed. The left and right wing anti−ice ducts are removed. Protective blankets are installed on the upper surface of the wing box and some fuel tubes. The left and right wing anti−ice ducts are installed. Some ceramic inserts in the connector of the sensing elements are replaced and dielectric compound is applied. New sensing elements are installed in the wheel well and the overwing. The overwing access panels and the wheel bins are installed. Circuit breakers are closed. The initiation test for the bleed leak system is done.

### (b) The distance between the sensing elements and the fuel tube insulation is 0.28 in. (7.1 mm) minimum. (c) The distance between the sensing elements and the coupling cover is 0.59 in. (15 mm) minimum. For aircraft 10003 thru 10121 and 15001 thru 15008 

### (94) Near FS752.00, make sure that the distances between the sensing element (4) and the adjacent fitting are as follows (refer to view Z): (a) The distance between the sensing element (4) and the forward area of the fitting is 0.63 in. (16.0 mm) minimum. (b) The distance between the sensing element (4) and the aft area of the fitting is 0.51 in. (12.9 mm) minimum. (c) The distance between the sensing element (4) and the bucked−tail of the rivet is 0.060 in. (1.52 mm) minimum. For aircraft 10122 thru 10331 and 15009 thru 15279 

### (95) Near FS752.00, make sure that the distances between the sensing element (4) and the adjacent fitting are as follows (refer to view Z): (a) The distance between the sensing element (4) and the forward area of the fitting is 0.50 in. (12.7 mm) minimum. (b) The distance between the sensing element (4) and the aft area of the fitting is 0.40 in. (10.2 mm) minimum. (c) The distance between the sensing elements and the coupling cover is 0.59 in. (15 mm) minimum. For all aircraft 

### (96) Make sure that the distance between the sensing elements (3) and (4) and the brackets is 0.25 in. (6.4 mm) minimum, unless otherwise specified in this service bulletin. (97) Make sure that the distance between the sensing elements (3) and (4) and the ducts, coupling covers, and bellows is 0.85 in. (21.6 mm) minimum, unless otherwise specified in this service bulletin.

### Refer to Figure 10. (98) Put the grommets (7) on the sensing elements (1) and (2) in line with the dual clamps (9). (99) Close and lock the dual clamps (9) with the quick−release screws. (100) Put the grommet (8) on the sensing elements (1) and (2) and the support. (101) For the left side, install the conduit (11) with the cable tie (10) on the sensing elements (1) and (2) (refer to view R) (ESPM 20−12−00). (102) Cut and discard the unwanted part of the cable tie (10). (103) For the right side, install the conduit (11) with the cable tie (10) on the sensing elements (1) and (2) (refer to view T) (ESPM 20−12−00). (104) Cut and discard the unwanted part of the cable tie (10). (105) If necessary, adjust the position of the sensing elements (1) and (2) to make sure that they point toward the vent holes in the ducts. (106) For the left side, make sure that the distances between the sensing elements (1) and (2) and the adjacent structure or components are as follows (refer to view R): (a) The distance between the upper sensing element and the support tube is 0.12 in. (3.1 mm) minimum. (b) The distance between the upper sensing element and the support tube is 0.70 in. (17.8 mm) minimum. (c) The distance between the sensing elements (1) and (2) and the adjacent electrical cables is 0.36 in. (9.1 mm) minimum. (107) Make sure that the distance between the sensing elements (1) and (2) and the brackets is 0.25 in. (6.4 mm) minimum, unless otherwise specified in this service bulletin. (108) Make sure that the distance between the sensing elements (1) and (2) and the ducts, coupling covers, and bellows is 0.85 in. (21.6 mm) minimum, unless otherwise specified in this service bulletin. (109) Make sure that the sensing elements (1) and (2) do not touch the new blankets.
