Incident at 55N 50W

Summary

1997-07-11: The B757 was out of Frankfort enroute New York at an altitude of 37,000 ft. At 55N 50W the crew reported that the left generator had failed and they were unable to start the APU at that altitude. The crew indicated that the APU might start at 33,000 ft. Gander ACC advised the B767 of traffic, a Delta Airlines flight at 35,000 ft. two minutes ahead then cleared the B767 to maintain 33,000 ft. There was no risk of collision as separation at the next reporting point had increased to five minutes. The TWA aircraft was travelling at .80 Mach and the Delta at .83 Mach. It is unclear as to whether the B767 used the contingency plan. TSB CLOSED. NAV CAN, will be conducting their own internal investigation.
