Narrative:
Lost left hydraulic after gear extension on lda runway 22 at lga. Went around, ran checklists, consulted dispatcher, landed ewr runway 22R (11000 ft). Fire equipment standing by as precaution. No nosewheel steering -- towed to gate. Callback conversation with reporter revealed the following information: the reporter stated the loss of the left main hydraulic system was caused by the left main gear extend pressure line failure. The reporter said loss of left main system pressure and quantity resulted in no trailing edge flap hydraulic control and loss of nose gear steering.

Title: A B757-200 ON APCH AT 1500 FT EXTENDED THE LNDG GEAR AND LOST THE L MAIN HYD SYS DUE TO FAILURE OF THE L MAIN GEAR DOWN LINE.
Narrative: LOST L HYD AFTER GEAR EXTENSION ON LDA RWY 22 AT LGA. WENT AROUND, RAN CHKLISTS, CONSULTED DISPATCHER, LANDED EWR RWY 22R (11000 FT). FIRE EQUIP STANDING BY AS PRECAUTION. NO NOSEWHEEL STEERING -- TOWED TO GATE. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED THE LOSS OF THE L MAIN HYD SYS WAS CAUSED BY THE L MAIN GEAR EXTEND PRESSURE LINE FAILURE. THE RPTR SAID LOSS OF L MAIN SYS PRESSURE AND QUANTITY RESULTED IN NO TRAILING EDGE FLAP HYD CTL AND LOSS OF NOSE GEAR STEERING.
