## Discrepancy

DURING THE OPERATIONAL/LEAK CHECK OF THE DOOR SEAL SYSTEM IT WAS NOTED THAT THE DOOR SEAL WOULD NOT INFLATE.  A HISSING NOISE (ESCAPE AIR) WAS NOTED AND TRACED BACK TO THE DRAIN VALVE (PN: 510343-1), THE STEM CAP WAS BROKEN OFF.  ALL PARTS WERE RECOVERED.  THIS WAS DISCOVERED DURING THE FIRST CLASS MOD.
