## Discrepancy

UPON SHUTDOWN A EXCEEDANCE WAS NOTED FOR HIGH HYDRAULIC PRESSURE. AFTER TROUBLESHOOTING / HUMS DOWNLOAD IT WAS NOTED THAT HYDRAULIC PRESSURE  HAD REACHED  3340 PSI. CONDUCTING RUNUPS RESULTED IN #2 HYDRAULIC PRESSURE NOT BEING VERY STEADY / VERY WEAK REGULATION. REPLACED #2 HYDRAULIC PUMP. AIRCRAFT RETURNED TO SERVICE.
