## Discrepancy

DURING AIRCRAFT CLEANING, FOUND AIRCRAFT TOILET LEAKING.  FOUND TANK UNIT LEAKING FROM IMPROPER REPAIR.  TOILET MAINTENANCE MANUAL DOES NOT PERMIT SEALING OF THE TANK UNIT.  TANK UNIT SHOULD BE REPLACED IF FOUND LEAKING DUE TO THE VERY REAL CORROSION PROBLEM FOUND IN THE BELLIES OF S550 AIRCRAFT.
