Narrative:

Departing cdg first officer flying; at approximately 120 KTS; the right engine generator tripped with right generator off EICAS message. Continued takeoff; climb; SID. Captain and second first officer ran left(right) generator off irregular checklist; unable to reset right generator; and started and ran APU. Sent 'call me' ACARS to dispatch. Contacted dispatch on satcom. 3-WAY crew/dispatch/maintenance on the call. After discussion determined ok to continue flight based on good WX en route and ETOPS alternates; additional APU burn; at approximately XA55Z got status message 'APU oil quantity' on lower EICAS. Asked dispatch to get maintenance input on this. Maintenance stated that with this message; the APU should be good for about 30 hours. Again; with crew and dispatch; decision made to continue flight. At approximately XC00Z; APU shut down automatically. Called dispatch on satcom and maintenance; got other first officer on break back-up to cockpit. Discussed possible diversion to kef. Maintenance agreed to try to reset the right generator by resetting the right main relay switch on first observer's panel. Field closed and generator brought on line. Again decision was to continue. I chose to leave utility busses off for minimum load on generators. Operations normal until about XG00Z when EICAS message right generator drive appeared. Captain came up from break after discussion again with dispatch/maintenance/crew diverted to nearest suitable airport (toronto) with 1 generator after disconnecting right drive per checklist. Normal descent/approach/landing. Excellent WX. Excellent CRM between crew; dispatch; maintenance; and flight attendants.

Title: B767-300 ON TRANSATLANTIC FLT SUFFERS MULTIPLE GENERATOR LOSSES RESULTING IN DIVERSION TO CYYZ.

Narrative: DEPARTING CDG FO FLYING; AT APPROX 120 KTS; THE R ENG GENERATOR TRIPPED WITH R GENERATOR OFF EICAS MESSAGE. CONTINUED TKOF; CLB; SID. CAPT AND SECOND FO RAN L(R) GENERATOR OFF IRREGULAR CHKLIST; UNABLE TO RESET R GENERATOR; AND STARTED AND RAN APU. SENT 'CALL ME' ACARS TO DISPATCH. CONTACTED DISPATCH ON SATCOM. 3-WAY CREW/DISPATCH/MAINT ON THE CALL. AFTER DISCUSSION DETERMINED OK TO CONTINUE FLT BASED ON GOOD WX ENRTE AND ETOPS ALTERNATES; ADDITIONAL APU BURN; AT APPROX XA55Z GOT STATUS MESSAGE 'APU OIL QUANTITY' ON LOWER EICAS. ASKED DISPATCH TO GET MAINT INPUT ON THIS. MAINT STATED THAT WITH THIS MESSAGE; THE APU SHOULD BE GOOD FOR ABOUT 30 HRS. AGAIN; WITH CREW AND DISPATCH; DECISION MADE TO CONTINUE FLT. AT APPROX XC00Z; APU SHUT DOWN AUTOMATICALLY. CALLED DISPATCH ON SATCOM AND MAINT; GOT OTHER FO ON BREAK BACK-UP TO COCKPIT. DISCUSSED POSSIBLE DIVERSION TO KEF. MAINT AGREED TO TRY TO RESET THE R GENERATOR BY RESETTING THE R MAIN RELAY SWITCH ON FIRST OBSERVER'S PANEL. FIELD CLOSED AND GENERATOR BROUGHT ON LINE. AGAIN DECISION WAS TO CONTINUE. I CHOSE TO LEAVE UTILITY BUSSES OFF FOR MINIMUM LOAD ON GENERATORS. OPS NORMAL UNTIL ABOUT XG00Z WHEN EICAS MESSAGE R GENERATOR DRIVE APPEARED. CAPT CAME UP FROM BREAK AFTER DISCUSSION AGAIN WITH DISPATCH/MAINT/CREW DIVERTED TO NEAREST SUITABLE ARPT (TORONTO) WITH 1 GENERATOR AFTER DISCONNECTING R DRIVE PER CHKLIST. NORMAL DSCNT/APCH/LNDG. EXCELLENT WX. EXCELLENT CRM BTWN CREW; DISPATCH; MAINT; AND FLT ATTENDANTS.
