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.MODEL BD-700-1A11 (BD-700)
