B. Reason
1. Condition:
After the deployment functional test of the oxygen masks at a scheduled
maintenance, Bombardier Service Center reported that four hoses used for the
passenger oxygen were found damaged.
2. Evidence:
After investigation, it was found that over time, the O2C20T1 series hoses may
have leak points in them through structural cracks or breaks, and may become
rigid or brittle at some areas.
3. Objective/Benefit:
The intent of this Service Bulletin is to remove and replace all installed
O2C20T1 series flexible oxygen hoses, with 3891X series hoses.
Engineering evaluation has concluded that 3891X series flexible oxygen hoses,
which are manufactured from different materials, have shown no sign of
deterioration due to age or other environmental factors.
C. Description
This Service Bulletin gives instructions in PART A to:
− Inspect the hose assembly installations located in the crew rest PSU, the cabin
PSUs, the RHS dado (therapeutic oxygen) and the AFT flexible transitions,
− Inspect the hose assembly installations located behind the FWD lavatory
headliner, the entrance area headliner (jumpseat, entrance) and the FWD
flexible transitions,
− Inspect the hose assembly installations located in the flight compartment and
the third crew (LHS enclosure),
− Fill out Appendix 1 with the affected O2C20T1 series flexible oxygen hoses part
numbers found installed, and
− Order the replacement parts as required and per aircraft configuration.
This Service Bulletin gives instructions in PART B to:
− Remove the O2C20T1 series hoses, and
− Install the 3891X series hoses as per Figure 2.
After PART A and PART B, this Service Bulletin gives instructions to:
− Do the necessary tests of the oxygen system.

6. Make sure that you do not make a scratch on the sealing
surfaces during installation.
7. Oxygen lines must be mounted above wires, fuel and hydraulic
system lines.
8. Oxygen lines spaced 6 in (152 mm) away from wires need no
special protection.
9. Oxygen lines spaced 6 to 2 in (152 to 50 mm) from wires shall
require to be sheathed in conduit or be securely clamped and
have cable ties installed at intervals less than the distance
between the wiring and oxygen lines.
10.Oxygen lines spaced 2 to 0.5 in (50 to 12 mm) from wires shall
require wires to be encased in insulated conduit and securely
clamped. These clamps shall not be used for support of wires.
11.Oxygen lines separated from wiring by conductive barrier may be
spaced 0.5 in (12 mm) from the wires.
12.Oxygen lines must be spaced 6 in (152 mm) from fuel, oil,
hydraulics, engine, flight linkage and any moving parts.
13.Where oxygen line crosses electrical, hydraulic or fuel lines,
protect for 6 in (152 mm) each side of crossing by covering with
convolex.
CAUTION: USE TWO WRENCHES WHEN YOU REMOVE/TORQUE THE
HOSES/TUBES.  USE ONE WRENCH TO HOLD THE FITTING,
AND THE OTHER WRENCH TO LOOSEN/TORQUE THE
COUPLING NUT.  IF YOU DO NOT DO THIS, YOU CAN
CAUSE DAMAGE TO THE COMPONENTS.
CAUTION: MAKE SURE THAT YOU PUT A PROTECTIVE COVER OR
CAP IN ALL THE OPEN OXYGEN LINES AND COMPONENT
FITTINGS. IF YOU DO NOT DO THIS IMMEDIATELY AFTER
THEY ARE DISCONNECTED, UNWANTED MATERIALS CAN
GO INTO THE OXYGEN SYSTEM. THIS CAN CAUSE
CONTAMINATION OF THE OXYGEN SYSTEM.
(a) Disconnect and discard the O2C20T1 series hoses.
CAUTION: NO TEFLON TAPE IS TO BE USED ON MALE FLARED
THREADS, COUPLING SLEEVES, OR ON THE OUTSIDE OF
