## Narrative

As the FAA filed it, in capitals; the FAA replaces private details with ^PRIVACY DATA OMITTED^.

WHILE IN CRUISE ENROUTE FROM YYZ TO CHS, CREW ENCOUNTERED A HYD 2 LO QTY EICAS MESSAGE. AT THAT TIME QTY WAS AT 22%. WITHIN FIVE MINUTES HYD 2 LO PRESSURE AND THE QUANTITY WAS AT 0%.

ATC WAS ADVISED THAT THE FLIGHT NEEDED TO RETURN TO YYZ DUE TO WEATHER CONCERNS IN CHS.  CREW CARRIED OUT HYD 2 LO PRESSURE QRH CHECKLIST AND LOSS OF HYDRAULIC SYSTEM 2. THE AIRCRAFT WAS OVER MAX LANDING WEIGHT BY ABOUT 630KGS INITIALLY, AND CREW ADVISED ATC THEY WOULD REQUIRE A HOLD FOR ABOUT THIRTY MINUTES TO BURN EXCESS FUEL. PAN PAN WAS DECLARED. THE CREW ALSO REQUESTED LOWER ALTITUDE IN ORDER TO RUN THE APU IN ATTEMPT TO BURN FUEL FASTER. THE AIRCRAFT LANDING ON 33R WAS UNEVENTFUL. FIRE SERVICES MET THE AIRCRAFT PRIOR TO TOW TO GATE.

From the FAA Accident/Incident Data System. Reports are matched to registry aircraft by N-number and event date, checked against the reported make and model; the registry's history has gaps, so older matches can be wrong. Compare the reported make and model. For accidents, the NTSB's own investigation is the fuller record.
