Thus, this Service Bulletin will no longer be applicable. ### Page 5 MODEL CL-600-2B16 Basic Issue: Nov 10/2008 604-29-008Revision 04: Jun 11/2015 Page 2 of 14 1. PLANNING INFORMATION NOTE: This Service Bulletin is mandated by Airworthiness Directive (AD) CF-2009-39 and FAA AD 2010-14-05. A. Effectivity CL-600-2B16 aircraft, Serial No. 5301 to 5665. NOTES: 1. Affected accumulators were installed in production starting on aircraft Serial No. 5525. Accumulators may have been installed as replacement parts on all other service Aircraft. 2. 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. B. Reason Field evidence has shown from the Regional jet family that the system and brake accumulator screw caps are susceptible to cracking after 3750 flight cycles. This could possibly lead to a screw cap and end cap release, which in turn may cause damage to the aircraft structure and/or systems. This Service Bulletin gives instructions to replace all the accumulators. C. Description This Service Bulletin gives instructions to: – Get access to system accumulators No. 1, No. 2 and No. 3, – Get access to brake accumulators No. 2 and No. 3, – Replace the affected accumulators, and – Do the necessary tests to make sure the system operates correctly. ### Page 6 MODEL CL-600-2B16 Basic Issue: Nov 10/2008 604-29-008Revision 04: Jun 11/2015 Page 3 of 14 D. Compliance Accumulators (Vendor Part No. 08-60163-002 and BA Spec No. 601R75138-1) and (Vendor Part No. 08-60164-002 and BA Spec No. 601R75138-3) with no suffix or suffix, “T”, or “TNA” at the end of the serial number, found at the end of the serial number must be replaced at 3750 flight cycles (accumulator time). For affected accumulators that have more than 3650 flight cycles at the release date of this Service Bulletin Revision 04, replace the affected accumulators within 100 flight cycles from the Service Bulletin Revision 01 Release, dated, Jul 06/2009. NOTES: 1. Accumulators with the suffix “TNAE” at the end of the serial number are the latest version and do not require replacement at 3750 flight cycles. Thus, this Service Bulletin will no longer be applicable and the TLMC applies. 2. A life limit is applicable on all new (Vendor Part No. 08-60163-002 and BA Spec No. 601R75138-1) and (Vendor Part No. 08-60164-002 and BA Spec No. 601R75138-3) with the suffix “TNAE” at the end of the serial number and can be found in the Life Limits (Systems) section 5-10-11 of the CL-604 Time Limits/Maintenance Checks (TLMC) manual. 3. This Service Bulletin is mandated by Airworthiness Directive (AD) CF- 2009-39 and FAA AD 2010-14-05. Due to a limited quantity of spare accumulators, we strongly suggest that the Service Bulletin be accomplished only at the due cycles. 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. ### Page 7 MODEL CL-600-2B16 Basic Issue: Nov 10/2008 604-29-008Revision 04: Jun 11/2015 Page 4 of 14 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 604-00-002. 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. 20 man-hours are necessary to do each modification. Bombardier does not pay for the labor to do this modification. G. Material – Cost and Availability No kit is necessary to do this modification. For material data, refer to Paragraph 3. NOTES: 1. Make sure that the replacement accumulators are new units that have the suffix “TNAE” at the end of the serial number. If you are receiving documents specifying that your accumulator is other than stated above, contact Bombardier Aerospace Parts Services, Montreal. 2. Accumulators with the suffix “TNAE” at the end of the serial number are the latest version and do not require replacement at 3750 flight cycles. Thus, this Service Bulletin will no longer be applicable. 3. A life limit is applicable on all new accumulators (Vendor Part No. 08-60163-002 and BA Spec No. 601R75138-1) and (Vendor Part No. 08-60164-002 and BA Spec No. 601R75138-3) with the suffix “TNAE” at the end of the serial number and can be found in the Life Limits (Systems) section 5-10-11 of the CL-604 Time Limits/Maintenance Checks (TLMC) manual. 4. Accumulators with no suffix, or “T”, or “TNA” at the end of the serial number, still require replacement at 3750 flight cycles. For those aircraft in new aircraft warranty at the time of Service Bulletin distribution, Smart Parts Plus does not pay for replacement accumulators at any time. For those aircraft with affected accumulators that have less than 3650 cycles (accumulator time), Smart Parts Plus does not pay for the accumulators to accomplish this Service Bulletin. For those aircraft out of new aircraft warranty with affected accumulators that have 3650 cycles or more (accumulator time) and require replacement in accordance with this Service Bulletin, Smart Parts Plus pays for the replacement accumulators. ### Page 8 MODEL CL-600-2B16 Basic Issue: Nov 10/2008 604-29-008Revision 04: Jun 11/2015 Page 5 of 14 H.
