## Discrepancy

IN CRUISE FLIGHT AT FL 350, WE HEARD A LOUD THUMP & BANG FROM REAR OF CABIN.  EXPERIENCED A RAPID DECOMPRESSION AT THIS POINT, CABIN CLIMB OF 2000 FPM PLUS.  FOLLOWED PROPER CHECKLIST PROCEDURES, MANUALLY DEPLOYED PASSENGER MASKS.  TROUBLESHOOTING REVEALED A LOOSE RUBBER BOOT BETWEEN THE WATER SEPARATOR AND J-DUCT.  THIS CAUSED A MAJOR LEAK AND PREVENTED THE AIRCRAFT FROM PRESSURIZING.  TIGHTENED RUBBER BOOT CLAMP.  PRESSURIZED AIRCRAFT,  LEAK CHECKED CLAMP, LEAK CHECK GOOD IAW M/M CH 21-10-15.
