SPECIAL CHECK/MODIFICATION – OXYGEN SUPPLY SYSTEM – INSPECTION AND 

REPLACEMENT OF OXYGEN CYLINDER AND REGULATOR ASSEMBLY (CRA) 

AND REGULATOR ASSEMBLIES WITH SPECIFIC SERIAL NUMBERS 

1. PLANNING INFORMATION 

NOTES: 1. This Service Bulletin is also applicable for the Oxygen Cylinder and 

Regulator Assemblies (CRA) and regulator assemblies in the operator’s 

stock room with Part No. 806371-311 and 806371-340 and 

Part No. 806370-12. 

2. A secondary Cylinder and Regulator Assembly (optional) may have 

been installed during production or by STC. 

3. It is recommended to do SB 605-24-005 (if applicable) at the same time 

as this Service Bulletin. 

A. Effectivity 

CL-600-2B16 aircraft, Serial No. 5701 to 5802, 5804 to 5808, 5810 to 5816, 5819, 

5822 to 5823. 

CRAs Part No. 806371-311 and 806371-340 held as spares. 

CL-600-2B16 aircraft, Serial No 5803, 5809, 5817, 5818, 5820, 5821, 5824 and all 

other subsequent CL-600-2B16 aircraft have been modified or are scheduled for the 

modification in production (Ref.: RSI C-4065). 

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). 

Before you do this bulletin, examine all STC, STA or equivalent 

action changes to make sure that this bulletin can be completed.

Revision 01: Feb 28/2011 Page 2 of 13 

B. Reason 

The “898 Series” oxygen Cylinder & Regulator Assemblies (CRA) could lead 

to oxygen leakage. 

Deformations were found at the neck of the pressure regulator bodies on 

two different units while undergoing routine inspections. The deformation 

is attributed to two batches of raw material not meeting the required tensile 

strength. This may cause the material at the threaded vicinity of the pressure 

regulator neck to elongate resulting in oxygen leakage. 

To date, AVOX Systems (the manufacturer) have found no instances of oxygen 

leakage related to this issue. This Service Bulletin replaces affected CRAs with 

upgraded CRAs eliminating any possibility of oxygen leakage. 

NOTE: The baseline oxygen system on the Challenger 605 is equipped 

with one 115 ft3 CRA mounted inside the wardrobe enclosure and a 

second (optional) 40 ft3 CRA mounted under the flight deck. Both 

mentioned CRAs can be affected. 

C. Description 

This Service Bulletin gives instructions to: 

– Access the 115 ft3 CRA and regulator assemblies and verify the serial numbers, 

– Access the 40 ft3 CRA (if installed) and regulator assemblies and verify the serial 

numbers, 

– Replace the affected CRAs (if any) with replacement CRAs, and 

– Do the necessary leak test and operational test of the system. 

D. Compliance 

Recommended within 750 flight hours from the release of this Service Bulletin 

(Basic Issue) or before December 31, 2011, whichever comes first. 

NOTE: This Service Bulletin is in reference to Advisory Wire AW600-35-2361. 

E. Approval 

The technical content of this Service Bulletin has been approved under 

the authority of Transport Canada Civil Aviation (TCCA) Design Approval 

Organization (DAO) No. DAO #93-Q-02. 

NOTES: 1. The technical content of this Service Bulletin is accepted by the

F. Manpower 

NOTES: 1. The man-hours given are estimates to help you schedule the tasks 

given in this bulletin. The estimates are for direct labor performed by 

an experienced crew and do not include the time for familiarization, 

planning, aircraft preparation in hangar such as towing and positioning 

of scaffolds, removal of interior furnishings, repainting, supervision and 

inspection. 

For more information related to the manpower estimates, refer to 

SB 605-00-002. 

2. This Service Bulletin may require consumable materials that have 

specific curing times (refer to Paragraph 3). The accumulated curing 

time is not included in the labor estimates and should be considered 

for planning purposes before you schedule this Service Bulletin. 

1 man-hour is necessary to do the special check for both CRAs (if required). 

1.5 man-hours are necessary to replace the 115 ft3 CRA and do the required tests. 

1.5 man-hours are necessary to replace the 40 ft3 CRA (if required) and do the 

required tests. 

The labor required to do this Service Bulletin is at no cost if: 

(i) the work is done at Bombardier Business Aviation Services (BBAS) 

or Authorized Service Facilities (ASF), and 

(ii) this Service Bulletin is scheduled within the stated compliance time.

G. Material - Cost and Availability 

The parts listed in Paragraph 3.B., may be necessary to do this Special Check/ 

Modification. Refer to the table that follows for the applicable aircraft effectivity: 

KIT/PART NO. ITEM AIRCRAFT EFFECTIVITY 

806371-311 115 ft3 CRA (Baseline) 5701 to 5848

806371-340 40 ft3 CRA (Optional) 5701 to 5848

NOTE: Some aircraft are equipped with a second optional CRA, Part No. 

806371-140 or -340. The -140 CRA is not affected by this Special 

Check/Modification. 

Bombardier Aerospace pays for the parts to do this Special Check/Modification. 

The oxygen cylinder and regulator assemblies (CRA) are available at no cost 

if a no-charge purchase order is sent to Bombardier Aerospace within the 

compliance time from this Service Bulletin release date (Basic Issue). 

NOTE: Due to the lead-time for obtaining parts, operators are advised to do the 

special check first to determine if there are faulty CRA’s installed on the 

aircraft and if necessary, to order the parts in advance before scheduling 

the incorporation of this Service Bulletin. Please contact Parts Logistics, 

in Montreal, for delivery lead times. 

This Service Bulletin is covered by a dedicated schedule. To ensure a timely 

and effective return/upgrade program, advance scheduling is required through our 

In-Service Implementation Team (ISIT). Please contact your Regional Manager 

(RM), Field Service Representative (FSR) or Customer Service Representative 

(CSR) as soon as is practical to schedule your aircraft. 

Send the old oxygen cylinder and regulator assemblies (CRA), Part No. 806371-311 

(115 ft3.) and/or 806371-340 (40 ft3), to the address shown below:
