The Canadian TSB reported shortly after departure the L1 variable frequency starter generator (VFSG) failed. The applicable procedure required the continuous use of the APU for the remainder of the flight. However, the continuous use of the APU for the 12 hours of the flight together with the normal fuel burn of both engines required more fuel to reach the destination than was on board. The crew therefore decided to divert to San Francisco, where the L1 VFSG was deactivated according to the minimum equipment list requirements.
The occurrence aircraft remained on the ground in San Francisco for about 3:45 hours, then continued the journey and reached Beijing with a delay of 8:15 hours.
