Narrative:

When we extended the gear; a hydraulic line from the left system ruptured and we lost total hydraulic fluid about the time the flaps reached 25 degrees. Flaps were extended to 30 degrees with the alternate flap system. Since we had gear down and locked; flaps 30 degrees; and normal brakes on the right system; the approach was continued and a normal landing and stop was made. However; without nosewheel steering; a turn off the runway was made with differential power and brakes. Once off the runway we call for a tug and were towed to the gate.

Original NASA ASRS Text

Title: B757 FLT CREW HAS L HYD SYS FAIL; USES ALTERNATE SYS; LANDS WITHOUT INCIDENT.

Narrative: WHEN WE EXTENDED THE GEAR; A HYD LINE FROM THE L SYS RUPTURED AND WE LOST TOTAL HYD FLUID ABOUT THE TIME THE FLAPS REACHED 25 DEGS. FLAPS WERE EXTENDED TO 30 DEGS WITH THE ALTERNATE FLAP SYS. SINCE WE HAD GEAR DOWN AND LOCKED; FLAPS 30 DEGS; AND NORMAL BRAKES ON THE R SYS; THE APCH WAS CONTINUED AND A NORMAL LNDG AND STOP WAS MADE. HOWEVER; WITHOUT NOSEWHEEL STEERING; A TURN OFF THE RWY WAS MADE WITH DIFFERENTIAL PWR AND BRAKES. ONCE OFF THE RWY WE CALL FOR A TUG AND WERE TOWED TO THE GATE.
