Flight Crew Human Performance
Cabin Crew Human Performance
We pushed back from the gate for our flight to ZZZ1 everything was normal until we started to rotate for takeoff. Once we rotated I started to smell something in the air that at first smelled like an oily pack. As we climbed out it got worst. Then it started to smell like electrical smoke. As I looked around the cockpit I couldn't see the smoke in the air. Then the flight attendant called us to say that there is smoke everywhere in the cabin. We decided to come back to ZZZ. We checked in with ZZZ center and told them we have smoke in the cockpit and cabin and we would like to go back to ZZZ. All instrument readings seemed normal and we had no EICAS msges. We came around and made a normal landing except we landed over our maximum landing weight by 15000 pounds. The fire trucks met us after we cleared the runway and followed us to the gate. The smoke seemed to dissipate once we were on final and almost gone by the time we reached the gate. As we deplaned the passengers some said they saw black smoke coming from the right engine. Callback conversation with reporter revealed the following information: the reporter stated on final approach the cabin was beginning to clear of the smoke and on reaching the gate it was gone. The reporter said the oily smoke was caused by the right engine compressor bearing and bearing seal allowing oil to enter the pneumatic bleed system and into the air conditioning pack system. The reporter stated there was no EICAS warning and all instrumentation for the right engine was normal. The reporter said an emergency was declared and the engine was replaced.

Title: A B757-200 ON TKOF CLB AT 4000 FT DECLARED AN EMER AND DIVERTED DUE TO SMOKE IN CABIN AND COCKPIT. CAUSED BY R ENG FAILED BEARING AND BEARING SEAL.
Narrative: WE PUSHED BACK FROM THE GATE FOR OUR FLT TO ZZZ1 EVERYTHING WAS NORMAL UNTIL WE STARTED TO ROTATE FOR TKOF. ONCE WE ROTATED I STARTED TO SMELL SOMETHING IN THE AIR THAT AT FIRST SMELLED LIKE AN OILY PACK. AS WE CLBED OUT IT GOT WORST. THEN IT STARTED TO SMELL LIKE ELECTRICAL SMOKE. AS I LOOKED AROUND THE COCKPIT I COULDN'T SEE THE SMOKE IN THE AIR. THEN THE FA CALLED US TO SAY THAT THERE IS SMOKE EVERYWHERE IN THE CABIN. WE DECIDED TO COME BACK TO ZZZ. WE CHECKED IN WITH ZZZ CENTER AND TOLD THEM WE HAVE SMOKE IN THE COCKPIT AND CABIN AND WE WOULD LIKE TO GO BACK TO ZZZ. ALL INSTRUMENT READINGS SEEMED NORMAL AND WE HAD NO EICAS MSGES. WE CAME AROUND AND MADE A NORMAL LNDG EXCEPT WE LANDED OVER OUR MAX LNDG WT BY 15000 LBS. THE FIRE TRUCKS MET US AFTER WE CLRED THE RWY AND FOLLOWED US TO THE GATE. THE SMOKE SEEMED TO DISSIPATE ONCE WE WERE ON FINAL AND ALMOST GONE BY THE TIME WE REACHED THE GATE. AS WE DEPLANED THE PASSENGERS SOME SAID THEY SAW BLACK SMOKE COMING FROM THE R ENG. CALLBACK CONVERSATION WITH RPTR REVEALED THE FOLLOWING INFO: THE RPTR STATED ON FINAL APCH THE CABIN WAS BEGINNING TO CLEAR OF THE SMOKE AND ON REACHING THE GATE IT WAS GONE. THE RPTR SAID THE OILY SMOKE WAS CAUSED BY THE R ENG COMPRESSOR BEARING AND BEARING SEAL ALLOWING OIL TO ENTER THE PNEUMATIC BLEED SYSTEM AND INTO THE AIR CONDITIONING PACK SYSTEM. THE RPTR STATED THERE WAS NO EICAS WARNING AND ALL INSTRUMENTATION FOR THE R ENG WAS NORMAL. THE RPTR SAID AN EMER WAS DECLARED AND THE ENG WAS REPLACED.
