Narrative:

Departed ewr at XX09 local from runway 22R en route to iad (dulles). During climb out crew noted smoke in the cockpit and cabin. The captain declared an emergency and called for the 'smoke and fumes' emergency checklist items. The crew completed the checklist items while returning to ewr to land on runway 22R. The aircraft landed and taxied to awaiting equipment on taxiway G. Upon stopping the aircraft, the captain called for 'emergency evacuate/evacuation,' and the crew completed the checklist items. The passenger (13) exited through the 2 cabin emergency exits and the main entrance door. There were no injuries to the 13 passenger or to the 2 crew members. There was no damage to the aircraft noted on postflt walkaround, though a significant amount of oil was noted leaking from the #1 left engine cowling. The aircraft was towed to the gate without further incident. Callback conversation with reporter revealed the following information: reporter first officer idented the source of the smoke after the emergency was over and it was found that the #1 engine compressor bearing had failed. That allowed oil to enter the air- conditioning ducting and packs resulting in smoke in the aircraft. The oxygen masks were deployed, but the passenger didn't use them apparently because the smoke in the cabin wasn't too severe. Reporter states that the greatest distraction in the cockpit was the quick donning of oxygen masks which created great difficulty in cockpit communication.

CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: RPTR FO IDENTED THE SOURCE OF THE SMOKE AFTER THE EMER WAS OVER AND IT WAS FOUND THAT THE #1 ENG COMPRESSOR BEARING HAD FAILED. THAT ALLOWED OIL TO ENTER THE AIR- CONDITIONING DUCTING AND PACKS RESULTING IN SMOKE IN THE ACFT. THE OXYGEN MASKS WERE DEPLOYED, BUT THE PAX DIDN'T USE THEM APPARENTLY BECAUSE THE SMOKE IN THE CABIN WASN'T TOO SEVERE. RPTR STATES THAT THE GREATEST DISTR IN THE COCKPIT WAS THE QUICK DONNING OF OXYGEN MASKS WHICH CREATED GREAT DIFFICULTY IN COCKPIT COM.
