Bombardier would like to remind operators and maintenance personnel about the availability of a Lufthansa Technik nice HD Cabin Management System (CMS) software update. In February 2019, Bombardier released two Service Bulletins, 350-44-002 and 650-44-002, to introduce a new CMS software build using the latest template used by Lufthansa. The Configuration Server Database (CSDB) for all Challenger 350 and Challenger 650 aircraft was built using Template 07. 

These Service Bulletins were released due to the obsolescence of some units in the CMS and due to necessary software updates to accommodate the replacement units. An additional benefit of updating the CSDB to the latest template is that all the maintenance fixes will be incorporated on the aircraft. 

The Service Bulletins are recommended for all aircraft delivered with a CSDB not built with Template 07. The effectivity is 20501 to 20772 for the Challenger 350 aircraft and the effectivity is 6050 to 6131 for the Challenger 650 aircraft.  

Please contact your Bombardier Field Service Representative (FSR) or the Customer Response Centre (CRC) team 24/7 at 1-866-538-1247 if you require more information.
