Narrative:
2-3 mi outside OM sea (gear down, flaps 15-20 degrees) we received an avionics smoke light, followed shortly by continuous repetitive chime, fire warning in cargo compartment. Cockpit filled with heavy smoke. We declared an emergency and landed sea. We taxied clear of runway, shut down and evacuate/evacuationed aircraft. Smoke started to disappear when engines were shut down and electric power was removed. Captain's oxygen mask failed to work as expected during the emergency. Callback conversation with reporter revealed the following information: reporter said that there had been a recent APU change and that there was determined to be oil in the pneumatic ducting. Smoke was not produced until pack got hot due to a one pack operation on approach. The oxygen mask problem was found to be a manufacturer's defect that was researched by the company and corrected by the manufacturer. The problem did not appear on a normal test procedure during cockpit setup.
Original NASA ASRS Text
Title: A300 HAS SMOKE IN THE ACFT ON APCH TO SEA, DECLARES EMER, LANDS AND EVACS. RPTS OXYGEN MASK DID NOT WORK CORRECTLY.
Narrative: 2-3 MI OUTSIDE OM SEA (GEAR DOWN, FLAPS 15-20 DEGS) WE RECEIVED AN AVIONICS SMOKE LIGHT, FOLLOWED SHORTLY BY CONTINUOUS REPETITIVE CHIME, FIRE WARNING IN CARGO COMPARTMENT. COCKPIT FILLED WITH HVY SMOKE. WE DECLARED AN EMER AND LANDED SEA. WE TAXIED CLR OF RWY, SHUT DOWN AND EVACED ACFT. SMOKE STARTED TO DISAPPEAR WHEN ENGS WERE SHUT DOWN AND ELECTRIC PWR WAS REMOVED. CAPT'S OXYGEN MASK FAILED TO WORK AS EXPECTED DURING THE EMER. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR SAID THAT THERE HAD BEEN A RECENT APU CHANGE AND THAT THERE WAS DETERMINED TO BE OIL IN THE PNEUMATIC DUCTING. SMOKE WAS NOT PRODUCED UNTIL PACK GOT HOT DUE TO A ONE PACK OP ON APCH. THE OXYGEN MASK PROB WAS FOUND TO BE A MANUFACTURER'S DEFECT THAT WAS RESEARCHED BY THE COMPANY AND CORRECTED BY THE MANUFACTURER. THE PROB DID NOT APPEAR ON A NORMAL TEST PROC DURING COCKPIT SETUP.
