DOORS 

MODIFICATION – AFT EQUIPMENT-COMPARTMENT DOOR – 

MODIFICATION TO PREVENT FUEL INGRESS INTO THE AFT EQUIPMENT BAY 

1. PLANNING INFORMATION 

A. Effectivity 

BD-700-1A10 aircraft, Serial No. 9381 and 9432 to 9476. 

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.
