## Discrepancy

ACFT PERFORMED AN UNSCHEDULED LANDING, DUE TO LOSS OF CABIN PRESSURE AT 36,000 FT. DURING MX REVISION, THE LT WATER SEPARATOR DUCT WAS DETECTED LEAKING; SO THE AIR CONDITIONING, PNEUMATIC AND ANTI ICE SYS LEAK CHECKS WERE PERFORMED IAW MM 21-00-00, 36-00-00 AND 30-00-00, NO ADDITIONAL LEAKS WERE FOUND.
