## Discrepancy

PILOT REPORTS AUX HYDRAULIC ACCUMULATOR PRESSURE SHOWS ZERO PSI ON GAUGE.  UPON FURTHER INSPECTION FOUND AUX HYDRAULIC ACCUMULATOR TO BE FAILED INTERNALLY CAUSING SYSTEM PRESSURE TO BLEED THROUGH RESULTING IN ZERO PRESSURE READIN ON AUX HYDRAULIC GAUGE.  COMPLIED WITH REPLACEMENT OF AUX HYDRAULIC ACCUMULATOR, PRESSURIZED SYSTEM AND FOUND GAUGE TO HOLD PRESSURE.  OPERATIONS CHECKED GOOD, AIRCRAFT OK FOR RETURN TO SERVICE.
