S.B. 84-26-15 Page 2 of 18 07 Jun 2013 Revision ‘A’ 15 Jan 2014 JR NOTE: The instructions in this service bulletin are only applicable to the systems and parts installed at the time of delivery on the aircraft or as changed by Bombardier Aerospace Service Bulletin(s). Before you do this bulletin, examine all STC or equivalent action changes to make sure this bulletin can be completed.
Spares Affected: None B. Reason Problem: There have been reports of severe corrosion on the firex distribution lines to the forward baggage compartment which has resulted in perforations of some of the tubes. This could result in insufficient extinguishing agent reaching the forward baggage compartment in the event of a fire situation. Solution: This service bulletin provides instructions to inspect the tubes for leaks and instructions to replace the alumunum tubes with stainless steel tubes. C. Description The procedures in this service bulletin give the instructions to do the tasks that follow: - aircraft is put into standard configuration for maintenance - aircraft electrical power is removed - the nose landing gear lock is engaged - the main landing gear lock pins are installed thru each main gear and main gear door mechanism - the discharge head tube in the forward baggage compartment is plugged with a plug - dry nitrogen is connected to the aft pressure bulkhead connection - the tubing is pressurized to check for leaks - if no leaks are found, system is put back to normal and the leak test is repeated after a specific period until all tubes are replaced with stainless steel - If leak test fails, all aluminum tubing is replaced before next flight - or the forward baggage compartment is placarded to inhibit use of forward baggage compartment until the aluminum tubing is replaced with stainless steel tubing within 10 days - a leak check is done on the new tubes - close out.
