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

FAA under the Canada/USA bilateral Aviation Safety Agreement. 2. The technical content of this Service Bulletin is accepted by the JAA and by EASA in accordance with established procedures.MODEL CL-600-2B16

Revision 01: Feb 28/2011 Page 3 of 13 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.MODEL CL-600-2B16

Revision 01: Feb 28/2011 Page 4 of 13 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: Learjet Core Returns 8219 West Irving, Bldg 9, Dock 9, Wichita, KS 67209 USA
NOTE : Refer to Avox Systems Inc., Service Information Letter SIL-35-126 for shipment of CRA. During or after the above free period, Smart Parts Plus does not pay for the parts.MODEL CL-600-2B16
