Narrative:

EICAS status message depicted low left hydraulic quantity. Shortly thereafter the following status messages appeared: left hydraulic system pressure. Left hydraulic reservoir pressure. Rudder ratio. Power transfer unit. We then followed the appropriate abnormal procedures in the aircraft operating manual for each item. We then contacted msp flight dispatch and maintenance control and notified them of our situation and our requests for emergency equipment and maintenance assistance and priority handling by approach control at our destination airport. The flight attendants were briefed for the approach, landing, what to expect on the ground. A 'PA' was made to the passenger on the approach so as not to scare them when they saw all the emergency vehicles. The gear flaps were extended using the alternate method and a normal landing was made. There was a total loss of nose wheel steering but we were able to exit the runway via the high speed taxiway by using differential braking. We were then towed to the gate. A visual inspection revealed that the left main gear hydraulic line had ruptured.

Title: ACR HAS EICAS MESSAGE OF HYD PROBLEMS. REQUESTS EMER EQUIP, PRIORITY HANDLING, LANDS.

Narrative: EICAS STATUS MESSAGE DEPICTED LOW L HYD QUANTITY. SHORTLY THEREAFTER THE FOLLOWING STATUS MESSAGES APPEARED: L HYD SYS PRESSURE. L HYD RESERVOIR PRESSURE. RUDDER RATIO. PWR TRANSFER UNIT. WE THEN FOLLOWED THE APPROPRIATE ABNORMAL PROCS IN THE ACFT OPERATING MANUAL FOR EACH ITEM. WE THEN CONTACTED MSP FLT DISPATCH AND MAINT CTL AND NOTIFIED THEM OF OUR SITUATION AND OUR REQUESTS FOR EMER EQUIP AND MAINT ASSISTANCE AND PRIORITY HANDLING BY APCH CTL AT OUR DEST ARPT. THE FLT ATTENDANTS WERE BRIEFED FOR THE APCH, LNDG, WHAT TO EXPECT ON THE GND. A 'PA' WAS MADE TO THE PAX ON THE APCH SO AS NOT TO SCARE THEM WHEN THEY SAW ALL THE EMER VEHICLES. THE GEAR FLAPS WERE EXTENDED USING THE ALTERNATE METHOD AND A NORMAL LNDG WAS MADE. THERE WAS A TOTAL LOSS OF NOSE WHEEL STEERING BUT WE WERE ABLE TO EXIT THE RWY VIA THE HIGH SPD TAXIWAY BY USING DIFFERENTIAL BRAKING. WE WERE THEN TOWED TO THE GATE. A VISUAL INSPECTION REVEALED THAT THE L MAIN GEAR HYD LINE HAD RUPTURED.
