## Discrepancy

(CAN) AIRCRAFT DEPARTED AIRPORT AND SHORTLY AFTER BOTH HYDRAULIC ANNUNCIATOR LIGHTS CAME ON INDICATING LOW HYDRAULIC PRESSURE.  AIRCRAFT RETURNED TO ALTERNATE AIRPORT DUE TO WEATHER AT ORIGINAL AIRPORT AND LANDED WITHOUT INCIDENT.  INVESTIGATION FOUND THAT THE HYDRAULIC LINE HAD BURST UNDER THE PILOTS FLOOR PANEL.  LINE REPLACED ALONG WITH BOTH HYDRAULIC PUMPS DUE TO CAVITATION REQUIREMENTS.
