Narrative:

The first officer's takeoff was routine until the gear up call. Landing gear retraction presented excessive and unusual noise during the nose gear retract cycle; but all gear indicated up and locked within the expected time frame. While passing 1300 ft wbound; the ECAM alerted us to the complete loss of quantity in the green hydraulic system. The ECAM hydraulics page displayed 3200 psi output in the green; and nominal values in both the blue and yellow system. I advised ATC that we had an aircraft system problem to sort out; would remain at 180 KTS maximum; and needed vectors for a return to ZZZ. Normal requests for people on board and fuel were answered; and then the radios were given to the first officer. I referenced the QRH for the abnormal procedure 'hydraulic rsvr lo level' and completed the procedure; securing both engine-driven green pumps; down to the left/G gravity ext procedural step. With the aircraft system secured; we briefed for the ILS runway approach; declared an emergency; and began the approach in visual conditions. The approach and landing were nominal; with the tower being told to have the emergency vehicles meet the aircraft at the intersection of runway and taxiway. I maneuvered the aircraft off the runway using differential braking; and stopped at the intersection of txwys. The aircraft was pwred down to APU; safetied; and the visual inspection by the emergency crews presented no leaks nor other abnormalities. We coordinated the tow-in; where maintenance found a leaking left aileron line.

Title: A300 FLT CREW HAS LOSS OF GREEN HYD SYS; DECLARES EMER AND RETURNS FOR LNDG.

Narrative: THE FO'S TKOF WAS ROUTINE UNTIL THE GEAR UP CALL. LNDG GEAR RETRACTION PRESENTED EXCESSIVE AND UNUSUAL NOISE DURING THE NOSE GEAR RETRACT CYCLE; BUT ALL GEAR INDICATED UP AND LOCKED WITHIN THE EXPECTED TIME FRAME. WHILE PASSING 1300 FT WBOUND; THE ECAM ALERTED US TO THE COMPLETE LOSS OF QUANTITY IN THE GREEN HYD SYS. THE ECAM HYDS PAGE DISPLAYED 3200 PSI OUTPUT IN THE GREEN; AND NOMINAL VALUES IN BOTH THE BLUE AND YELLOW SYS. I ADVISED ATC THAT WE HAD AN ACFT SYS PROB TO SORT OUT; WOULD REMAIN AT 180 KTS MAX; AND NEEDED VECTORS FOR A RETURN TO ZZZ. NORMAL REQUESTS FOR PEOPLE ON BOARD AND FUEL WERE ANSWERED; AND THEN THE RADIOS WERE GIVEN TO THE FO. I REFED THE QRH FOR THE ABNORMAL PROC 'HYD RSVR LO LEVEL' AND COMPLETED THE PROC; SECURING BOTH ENG-DRIVEN GREEN PUMPS; DOWN TO THE L/G GRAVITY EXT PROCEDURAL STEP. WITH THE ACFT SYS SECURED; WE BRIEFED FOR THE ILS RWY APCH; DECLARED AN EMER; AND BEGAN THE APCH IN VISUAL CONDITIONS. THE APCH AND LNDG WERE NOMINAL; WITH THE TWR BEING TOLD TO HAVE THE EMER VEHICLES MEET THE ACFT AT THE INTXN OF RWY AND TXWY. I MANEUVERED THE ACFT OFF THE RWY USING DIFFERENTIAL BRAKING; AND STOPPED AT THE INTXN OF TXWYS. THE ACFT WAS PWRED DOWN TO APU; SAFETIED; AND THE VISUAL INSPECTION BY THE EMER CREWS PRESENTED NO LEAKS NOR OTHER ABNORMALITIES. WE COORDINATED THE TOW-IN; WHERE MAINT FOUND A LEAKING L AILERON LINE.
