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.
