A B757-200 CREW DISCONNECTED A CSD FOLLOWING GENERATOR DRIVE WARNINGS. THE CSD'S DISINTEGRATION CAUSED ENG OIL QUANTITY AND PRESSURE TO DROP REQUIRING AN ENG SHUTDOWN. AN EMER WAS DECLARED; AND A DIVERSION TO A NEARBY ARPT.

Narrative

WHILE AT FL380 WITH CAPT AS PF; BOTH PRIMARY ENG DISPLAYS FLICKERED OFF FOR APPROX 1 SECOND AND RETURNED TO NORMAL. AFTER A MOMENT; EICAS R GENERATOR DRIVE AND R GENERATOR OFF; R UTILITY BUS OFF; L UTILITY BUS OFF; AS WELL AS; OVERHEAD R GENERATOR CTL LIGHTS ILLUMINATED. PERFORMED QRH CHKLIST FOR R GENERATOR DRIVE. AS PER PROC; DISCONNECTED R GENERATOR DRIVE. STARTED APU AND OBSERVED THAT BOTH UTILITY BUSES WERE NOW PWRED. ADVISED FLT ATTENDANTS THAT THEIR GALLEY PWR SHOULD NOW BE NORMAL. NOTIFIED MAINT COORDINATOR VIA ACARS OF OUR STATUS. APPROX 5 MINS LATER; CAPT OBSERVED R OIL QUANTITY INDICATOR READING ZERO. OIL PRESSURE WAS NORMAL (200 PSI) AT THIS TIME. APPROX 2 MINS LATER; OIL PRESSURE BEGAN FLUCTUATING; AS WELL AS STEADILY DECREASING. CAPT RECEIVED ATC CLRNC FOR DSCNT ANTICIPATING POSSIBLE ENG FAILURE. DURING THE DSCNT; THE R ENG OIL PRESSURE LIGHT ON THE FORWARD PANEL STARTED TO FLICKER AND SOON WAS FULLY ILLUMINATED. AS PER QRH LOW OIL PRESSURE PROC R THROTTLE WAS RETARDED TO IDLE. CAPT TOOK OVER ATC COMS AND DECLARED AN EMER WHILE FO ADVISED DISPATCHER AND MAINT COORDINATOR OF OUR STATUS AND INTENTION TO DIVERT. DISPATCHER CONCURRED THAT ZZZ WAS CLOSE AND EXCELLENT WX. CAPT LOADED FMS FOR THE DIVERT WHILE FO ADVISED FLT ATTENDANTS OF INTENTION TO DIVERT BUT THAT NO EVAC WAS EXPECTED ALTHOUGH EMER EQUIP WOULD BE STANDING BY. FO SUBSEQUENTLY MADE PAX PA. AS DIRECTED BY QRH; ACCOMPLISHED ENG SHUTDOWN PROC. PERFORMED DSCNT AND APCH CHKLIST FOR 'ENG OUT' ILS RWY 25R FLAPS 20 DEG LNDG. AUTO-BRAKES SET TO 2. CAPT FLEW COUPLED APCH TO APPROX 800 FT AGL. NORMAL LNDG AND ROLLOUT; EXITED RWY AT A7 AND STOPPED ON TXWY B. CAPT THEN MADE PA THAT ALL WAS WELL AND FIRE EQUIP WOULD BE CHKING R ENG. SPOKE WITH A-LINE AND VERIFIED ALL PAX WERE CALM AND SEATED. ARPT FIRE/RESCUE EXAMINED R ENG. UPON ARR AT GATE; MAINT RPTED INTERNAL DAMAGE AND SOME METAL PIERCING THE ENG COWLING. NOTIFIED MAINT; DUTY PLT AND CONFERENCE CALLED WITH CHIEF PLT. NOTE: I SEEM TO RECALL A PROC ON THE BOEING 727 TO VERIFY THAT THE GENERATOR DRIVE HAS BEEN DISCONNECTED. ALTHOUGH WE PRESSED THE DISCONNECT SWITCH TWICE; WE HAD NO MEANS IN OUR CHKLIST OR EICAS TO VERIFY THAT THE PROC HAS BEEN SUCCESSFUL. AS TO THE LEVEL OF AUTOMATION; THE TRAINING WITH USE OF THE AUTOPLT DURING ENG OUT OPS CAME IN VERY HANDY AND ALLOWED THE PF TO EASILY TRIM AND MONITOR THE ACFT. AT ONE POINT WITH AUTOPLT ON; WE DSNDED ABOUT 250 FT BELOW OUR ASSIGNED ALT. CTR ASKED ABOUT OUR ALT AND WE CORRECTED; ALTHOUGH WE DIDN'T HAVE AN AUTOPLT DEGRADED MODE ANNUNCIATION. DISCONNECTED AUTOPLT; LEVELED OFF AND REENGAGED AUTOPLT. THE FO RADIO CALLS TO COMPANY WERE LONGER THAN I EXPECTED DUE TO WHAT I BELIEVE WAS THE MAINT COORDINATOR'S QUEST FOR INFO. I WAS BUSY TALKING TO ATC; DECLARING AN EMER AND FLYING. IN HINDSIGHT WE SHOULD HAVE SHUT DOWN THE ENG A LITTLE SOONER THAN WE DID. MAINT COORDINATOR ADVISED US ON THE GND THAT SOMETIMES THE GENERATOR DRIVE DOES NOT DISCONNECT. MY UNDERSTANDING IS THAT THIS CAN LEAD TO A FIRE AND I WOULD LOVE TO SEE SEPARATE GENERATOR DRIVE DISCONNECT LIGHTS. WITH REGARD TO TRAINING; THE EVENTS WERE VERY MUCH LIKE MY LAST SIMULATOR LOE SO I HAD TIME TO THINK AND KEEP TRACK OF WHERE THE AIRPLANE WAS; WHERE WE WERE GOING AND HOW OUR PLAN WAS WORKING. LATER WHEN I MADE A PAX PA; I MENTIONED THAT THIS WAS JUST THE WAY WE TRAINED FOR IT IN THE SIMULATOR. I WAS GLAD THAT WE HAD THE ARPT FIRE/RESCUE STANDING BY AND MIGHT UPON RECONSIDERATION; HAVE BEEN TOWED TO THE GATE BY MAINT. LOOKING AT THE ENG WITH THE COWL OPEN; IT WAS VERY IMPRESSIVE THAT THE ENG HAD; IN FACT; RAN SO LONG WITH A ZERO OIL INDICATION. MY ZZZ FAMILIARITY THESE LAST 5 YRS CONTRIBUTED GREATLY TO SITUATION AWARENESS. ALSO; THE FACT THAT MOST ACR B757/B767 FO'S HAVE HAD AT LEAST 10 YRS COMPANY EXPERIENCE MADE FOR COMFORTABLE MANEUVER DESPITE THE FACT THAT IT WAS THE FIRST TIME THE CREW HAD FLOWN TOGETHER. I THINK THAT OUR CRM TRAINING; BOTH IN THE CLASSROOM AND THE SIMULATOR; HELPED MY PERFORMANCE.
