## Discrepancy

DURING TRANSIT CHECK, A HYDRAULIC LEAK WAS DETECTED IN THE HYDRAULIC SYSTEM B.  MAINTENANCE PERSONNEL PERFORMED REVISION DETECTING HYDRAULIC LEAK AT IN ACOUSTIC FILTER.  SO THE ACOUSTIC FILTER P/N 1013983-1, S/S, MANUFACTURER SUNDSTRAND WAS REPLACED, IAW AMM B-737 TASK 29-11-27.  HYDRAULIC RESERVOIR SERVICING WAS PERFORMED, IAW AMM B-737 TASK 12-12-00-601-801, ALL CORRECT.
