Narrative:

Shortly after takeoff engine advance light flashed and we noted engine oil quantity #1 engine was zero on ECAM and quantity gauge. Oil pressure and temperature were within normal range, but pressure was low indicating about 25-28 psi. Pulled #1 throttle to idle, declared an emergency, informed flight attendants and returned for landing at position. Landing weight was 317000 pounds. Sink rate 250 FPM and normal touchdown. #1 engine was shut down after landing. No other abnormal indications noted. Maintenance could not find source of leak, so after consulting with technician and engineering, oil was filled up and high power engine run-up commenced. Quantity immediately started toward zero and aircraft taken OTS.

Narrative: SHORTLY AFTER TKOF ENG ADVANCE LIGHT FLASHED AND WE NOTED ENG OIL QUANTITY #1 ENG WAS ZERO ON ECAM AND QUANTITY GAUGE. OIL PRESSURE AND TEMP WERE WITHIN NORMAL RANGE, BUT PRESSURE WAS LOW INDICATING ABOUT 25-28 PSI. PULLED #1 THROTTLE TO IDLE, DECLARED AN EMER, INFORMED FLT ATTENDANTS AND RETURNED FOR LNDG AT POS. LNDG WT WAS 317000 LBS. SINK RATE 250 FPM AND NORMAL TOUCHDOWN. #1 ENG WAS SHUT DOWN AFTER LNDG. NO OTHER ABNORMAL INDICATIONS NOTED. MAINT COULD NOT FIND SOURCE OF LEAK, SO AFTER CONSULTING WITH TECHNICIAN AND ENGINEERING, OIL WAS FILLED UP AND HIGH PWR ENG RUN-UP COMMENCED. QUANTITY IMMEDIATELY STARTED TOWARD ZERO AND ACFT TAKEN OTS.
