Flight Crew Air Transport Pilot (ATP)
Aircraft Equipment Problem Critical
Air Traffic Control Provided Assistance; Flight Crew Overcame Equipment Problem; Flight Crew Executed Go Around / Missed Approach
Climbing out of approximately 15;000 FT at about 300-315 KTS had L HYD QTY and L HYD SYS PRESS EICAS messages. We went to Status page and left hydraulic quantity showed 0.00RF. Performed loss of hydraulics for left system and turned off both left pumps (Engine Driven and Electric). Left system pressure on status page showed between 3050 and 3450 PSI (PTU pressure?). [We] reviewed systems with First Officer including Rudder Ratio and Yaw Damper malfunctions. Continued onto [our destination] and climbed to FL370. On arrival swapped duties with First Officer and flew the STAR and LOC XXL. [We] started lowering flaps early. Got flaps to 20. Upon lowering gear got a GEAR DISAGREE and I think at this time the POWER XFER UNIT Status message occurred. Did alternate gear extension and then tried to lower flaps further. [We] received a TE DISAGREE message. At this time we were about 800 FT and performed a Go Around. Completed checklists; came around and landed on [Runway] XXC. [We] cleared to the left on the high speed. After clearing we stopped and were towed in.Not much we could do to prevent the breakdown. In hindsight though; I should have declared an emergency. After the go around with the gear stuck down and the flaps at 20 we were going the wrong way burning 11;000 LBS/hour. Once requesting a turn downwind ATC was very accommodating and helped out by offering the center runway. First Officer was tremendous help.
When we looked at system display; all 3 hydraulic systems were being pressurized; but the quantity in the left was 0.00RF. We discussed implications of current situation. And then we discussed implications of further system failures. Aircraft was flying normally; so we decided to proceed to destination. As part of the discussion we kept ourselves appraised of potential landing sites should our situation digress. Cruise flight was normal.Upon reflection; we might have considered declaring an emergency; but the plane was behaving normally and crew was working the problems wisely and safely; so was unnecessary.
A B757-200 flight crew elected to continue to their destination after the left hydraulic system failed as they climbed through 15;000 FT after takeoff. Problems extending both the flaps and landing gear at their destination forced a go around and completion of associated abnormal procedure checklists. After landing they were towed to the gate.
