Narrative:

After takeoff lost left hydraulic system. I was flying. Captain handled emergency while I took vectors from approach. Told approach nature of emergency, souls and fuel. A little confusion as to what runway we were going to get but straightened it out with approach and landed runway 22L, shut down on runway because we had no nosewheel steering. We got towed in, emergency over. I do not feel anything was done to violate us, I'm just protecting myself. Thanks. Ps. Captain landed. Procedurally went well, something that could have been better. We could have initially asked for the longest runway that would have solved a confusion as to what runway we were being vectored to. Also on landing, I was fixed on the brake pressure since it stated we could possibly loose pressure on normal brakes in our crew operations manual. This caused me to not see that the speed brakes did not deploy by themselves. It also stated in our crew operations manual that they may or may not deploy by themselves. My attention was more on brake pressure and I forgot to scan the speed brakes. Callback conversation with reporter revealed the following information: the reporter stated the loss of the left main hydraulic system pressure and quantity was caused by a failed hydraulic pressure line in the main wheelwell. The reporter said it was unclr if the failed line was a solid or flexible line.

Title: A B757-200 AFTER TKOF IN CLB AT 8000 FT DECLARED AN EMER AND DIVERTED DUE TO LOSS OF L HYD SYS PRESSURE AND QUANTITY, CAUSED BY A FAILED HYD PRESSURE LINE IN THE MAIN WHEELWELL.

Narrative: AFTER TKOF LOST L HYD SYS. I WAS FLYING. CAPT HANDLED EMER WHILE I TOOK VECTORS FROM APCH. TOLD APCH NATURE OF EMER, SOULS AND FUEL. A LITTLE CONFUSION AS TO WHAT RWY WE WERE GOING TO GET BUT STRAIGHTENED IT OUT WITH APCH AND LANDED RWY 22L, SHUT DOWN ON RWY BECAUSE WE HAD NO NOSEWHEEL STEERING. WE GOT TOWED IN, EMER OVER. I DO NOT FEEL ANYTHING WAS DONE TO VIOLATE US, I'M JUST PROTECTING MYSELF. THANKS. PS. CAPT LANDED. PROCEDURALLY WENT WELL, SOMETHING THAT COULD HAVE BEEN BETTER. WE COULD HAVE INITIALLY ASKED FOR THE LONGEST RWY THAT WOULD HAVE SOLVED A CONFUSION AS TO WHAT RWY WE WERE BEING VECTORED TO. ALSO ON LNDG, I WAS FIXED ON THE BRAKE PRESSURE SINCE IT STATED WE COULD POSSIBLY LOOSE PRESSURE ON NORMAL BRAKES IN OUR CREW OPS MANUAL. THIS CAUSED ME TO NOT SEE THAT THE SPD BRAKES DID NOT DEPLOY BY THEMSELVES. IT ALSO STATED IN OUR CREW OPS MANUAL THAT THEY MAY OR MAY NOT DEPLOY BY THEMSELVES. MY ATTN WAS MORE ON BRAKE PRESSURE AND I FORGOT TO SCAN THE SPD BRAKES. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE LOSS OF THE L MAIN HYD SYS PRESSURE AND QUANTITY WAS CAUSED BY A FAILED HYD PRESSURE LINE IN THE MAIN WHEELWELL. THE RPTR SAID IT WAS UNCLR IF THE FAILED LINE WAS A SOLID OR FLEXIBLE LINE.
