Narrative:

During taxiing for takeoff at lax on taxiway south between north and south complex, the cabin starts to fill up with smoke and also smoke was coming out of the left engine. The aircraft behind us also reported smoke out of our left engine to the ground frequency. From the cockpit there was no visible fire or any indications of abnormalities. I declared an emergency. I notified ATC that we were evacing, requested fire trucks, and emergency evacuate/evacuation procedures were applied. Due to the amount of smoke coming out of left engine even after left engine was shut down both fire bottles were discharged. The evacuate/evacuation of 12 adults, 2 half weights, and 2 infants went without incident. Callback conversation with reporter revealed the following information: aircraft was a jetstream 31. Reporter stated that the postflt inspection found a leaking or failed propeller dome seal. The failed seal allowed oil to pass into the hot engine section, then passed the vapors and smoke through the inlet areas of the air- conditioning unit, thus filling the cabin with smoke via the gaspers. That was also the reason that the reporter had no warning system alert, as there was no fire, just the smoke. He had the passenger depart the aircraft via the aircraft stairs, by the smoking engine. The 2 factors that allowed that decision was the number of elderly persons and infants onboard and the fact that the crash fire rescue equipment vehicles arrived in less than 1 min and were outside the aircraft when the evacuate/evacuation was just getting underway. The incident took place near the fire station. When asked if the evacuate/evacuation checklist contained a full flap activation for overwing exiting, he said, 'no, the flaps were at 10 degrees for takeoff.' he did agree that an addition to that checklist encompassing flap extension for an evacuate/evacuation route over the wing would most likely be beneficial to exiting passenger.

Title: AN LTT HAS TO EVAC THE PAX ON THE TXWY AT LAX. SMOKE HAD FILLED THE CABIN AND WAS NOTED COMING FROM THE L ENG. NO UNUSUAL ALERTS OR ALARMS ASSOCIATED WITH INCIDENT. EMER DECLARED.

Narrative: DURING TAXIING FOR TKOF AT LAX ON TXWY S BTWN N AND S COMPLEX, THE CABIN STARTS TO FILL UP WITH SMOKE AND ALSO SMOKE WAS COMING OUT OF THE L ENG. THE ACFT BEHIND US ALSO RPTED SMOKE OUT OF OUR L ENG TO THE GND FREQ. FROM THE COCKPIT THERE WAS NO VISIBLE FIRE OR ANY INDICATIONS OF ABNORMALITIES. I DECLARED AN EMER. I NOTIFIED ATC THAT WE WERE EVACING, REQUESTED FIRE TRUCKS, AND EMER EVAC PROCS WERE APPLIED. DUE TO THE AMOUNT OF SMOKE COMING OUT OF L ENG EVEN AFTER L ENG WAS SHUT DOWN BOTH FIRE BOTTLES WERE DISCHARGED. THE EVAC OF 12 ADULTS, 2 HALF WTS, AND 2 INFANTS WENT WITHOUT INCIDENT. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: ACFT WAS A JETSTREAM 31. RPTR STATED THAT THE POSTFLT INSPECTION FOUND A LEAKING OR FAILED PROP DOME SEAL. THE FAILED SEAL ALLOWED OIL TO PASS INTO THE HOT ENG SECTION, THEN PASSED THE VAPORS AND SMOKE THROUGH THE INLET AREAS OF THE AIR- CONDITIONING UNIT, THUS FILLING THE CABIN WITH SMOKE VIA THE GASPERS. THAT WAS ALSO THE REASON THAT THE RPTR HAD NO WARNING SYS ALERT, AS THERE WAS NO FIRE, JUST THE SMOKE. HE HAD THE PAX DEPART THE ACFT VIA THE ACFT STAIRS, BY THE SMOKING ENG. THE 2 FACTORS THAT ALLOWED THAT DECISION WAS THE NUMBER OF ELDERLY PERSONS AND INFANTS ONBOARD AND THE FACT THAT THE CFR VEHICLES ARRIVED IN LESS THAN 1 MIN AND WERE OUTSIDE THE ACFT WHEN THE EVAC WAS JUST GETTING UNDERWAY. THE INCIDENT TOOK PLACE NEAR THE FIRE STATION. WHEN ASKED IF THE EVAC CHKLIST CONTAINED A FULL FLAP ACTIVATION FOR OVERWING EXITING, HE SAID, 'NO, THE FLAPS WERE AT 10 DEGS FOR TKOF.' HE DID AGREE THAT AN ADDITION TO THAT CHKLIST ENCOMPASSING FLAP EXTENSION FOR AN EVAC RTE OVER THE WING WOULD MOST LIKELY BE BENEFICIAL TO EXITING PAX.
