1. PLANNING INFORMATION  
A. Effectivity 
BD-700-1A10 aircraft, Serial No. 9002 to 9312, 9314 to 9380 and 9384 to 9429.   
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.   
B. Reason 
Several cases have been reported where fluid from the aft fuel tank drain was 
found to run back along the center line of the aircraft and entered the aft 
equipment bay via the slot in the door latch mechanism.   
This Service Bulletin provides instructions to install a cover to the aft equipment 
bay door latch mechanism.  This modification will reduce the risk of drain mast 
fluids from entering and accumulating in the aft equipment bay. 
C. Description 
This Service Bulletin gives instructions to: 
– Remove the aft equipment-compartment door, 
– Do the modification to the door, 
– Install the door, and 
– Do the necessary tests to make sure that the system operates correctly.
