 OVERBOARD DISCHARGE INDICATOR - REMOVAL/INSTALLATION
____________________________________________________
 1.  General_______
 A.  These tasks are included in this procedure:
 (1)  
Removal of the overboard discharge indicator.

 (2)  
Installation of the overboard discharge indicator.

 B.  The overboard discharge indicator is a plastic disc. Dirt, grease, and most other contaminants will not normally enter the overboard discharge line with the overboard discharge indicator installed. The overboard discharge indicator will blow out if the safety valve on the cylinder opens. This permits pressure in the overboard discharge line to increase to 500 psi.
 C.  The overboard discharge indicator is installed aft of the forward cargo door in the airplane skin (Fig. 401). Access is from outside of the airplane.
