Narrative:
At approximately PM05Z, while in cruise from san juan to newark on a scheduled flight, the #2 engine oil pressure went to 0. Initially all other engine indications were normal. As the crew discussed and analyzed the situation, approximately 1 min later, we got a generator out light, hydraulic off lights and 0 fuel flow with minimal N1 indication. The captain immediately initiated the engine shutdown checklist which was accomplished. At this time, I (first officer) tried to raise ny arinc to let them know of the situation and request a descent to FL250 from our cruising altitude of 350. Communications were very poor due to very busy airways and poor reception but the request was made. With the #2 engine shutdown and our gross weight, the airspeed slowly began to decay. As we began a slow descent because of airspeed considerations, ny arinc cleared us to FL250 requesting us to call out of 310 and 280. We were approximately 34.7 when we received the clearance to descend, at which time I informed them (ny arinc) that air carrier heavy had departed 350 for 250. We were in VFR conditions at the time with a small deviation around a cloud buildup and in no immediate danger of other aircraft. The rest of the flight was uneventful. We proceeded to newark as scheduled. We felt there was no need to declare an emergency since all other aircraft system were normal and we had viable alternates along our route. As a precaution, we called for the emergency vehicles at newark IAP. The landing at newark was accomplished in accordance with airline procedures without any complications and upon rollout the emergency vehicles were released. We taxied into parking. Supplemental information from acn 186707: #2 oil pressure indicated 0. Oil temperature was 115 and oil quantity was 13. #2 throttle was pulled to idle as crew analyzed problem. Shortly thereafter the #2 CSD oil pressure low light and #2 hydraulic pressure low light illuminated. The aircraft was stable and under control and since we had received descent clearance I felt it was not necessary to declare an emergency at this time.

Title: INFLT ENG SHUTDOWN. ACR WDB CONTINUES FLT TO EWR ARPT, FLT'S DEST.
Narrative: AT APPROX PM05Z, WHILE IN CRUISE FROM SAN JUAN TO NEWARK ON A SCHEDULED FLT, THE #2 ENG OIL PRESSURE WENT TO 0. INITIALLY ALL OTHER ENG INDICATIONS WERE NORMAL. AS THE CREW DISCUSSED AND ANALYZED THE SITUATION, APPROX 1 MIN LATER, WE GOT A GENERATOR OUT LIGHT, HYD OFF LIGHTS AND 0 FUEL FLOW WITH MINIMAL N1 INDICATION. THE CAPT IMMEDIATELY INITIATED THE ENG SHUTDOWN CHKLIST WHICH WAS ACCOMPLISHED. AT THIS TIME, I (FO) TRIED TO RAISE NY ARINC TO LET THEM KNOW OF THE SITUATION AND REQUEST A DSCNT TO FL250 FROM OUR CRUISING ALT OF 350. COMS WERE VERY POOR DUE TO VERY BUSY AIRWAYS AND POOR RECEPTION BUT THE REQUEST WAS MADE. WITH THE #2 ENG SHUTDOWN AND OUR GROSS WT, THE AIRSPD SLOWLY BEGAN TO DECAY. AS WE BEGAN A SLOW DSCNT BECAUSE OF AIRSPD CONSIDERATIONS, NY ARINC CLRED US TO FL250 REQUESTING US TO CALL OUT OF 310 AND 280. WE WERE APPROX 34.7 WHEN WE RECEIVED THE CLRNC TO DSND, AT WHICH TIME I INFORMED THEM (NY ARINC) THAT ACR HVY HAD DEPARTED 350 FOR 250. WE WERE IN VFR CONDITIONS AT THE TIME WITH A SMALL DEV AROUND A CLOUD BUILDUP AND IN NO IMMEDIATE DANGER OF OTHER ACFT. THE REST OF THE FLT WAS UNEVENTFUL. WE PROCEEDED TO NEWARK AS SCHEDULED. WE FELT THERE WAS NO NEED TO DECLARE AN EMER SINCE ALL OTHER ACFT SYS WERE NORMAL AND WE HAD VIABLE ALTERNATES ALONG OUR RTE. AS A PRECAUTION, WE CALLED FOR THE EMER VEHICLES AT NEWARK IAP. THE LNDG AT NEWARK WAS ACCOMPLISHED IN ACCORDANCE WITH AIRLINE PROCS WITHOUT ANY COMPLICATIONS AND UPON ROLLOUT THE EMER VEHICLES WERE RELEASED. WE TAXIED INTO PARKING. SUPPLEMENTAL INFO FROM ACN 186707: #2 OIL PRESSURE INDICATED 0. OIL TEMP WAS 115 AND OIL QUANTITY WAS 13. #2 THROTTLE WAS PULLED TO IDLE AS CREW ANALYZED PROBLEM. SHORTLY THEREAFTER THE #2 CSD OIL PRESSURE LOW LIGHT AND #2 HYD PRESSURE LOW LIGHT ILLUMINATED. THE ACFT WAS STABLE AND UNDER CTL AND SINCE WE HAD RECEIVED DSCNT CLRNC I FELT IT WAS NOT NECESSARY TO DECLARE AN EMER AT THIS TIME.
