1.0 Factual Information
1.1 History of the Flight
Air France flight 033 (AFR033)1, an Airbus A340 aircraft, was en route from Houston to Paris at
flight level (FL) 370 with a routing of WHALE, BANCS, and latitude 46°N longitude
50°W(Oceanic Track "X"). Air Canada flight 870 (ACA870), a Boeing B747 aircraft, was en route
from Montreal to Paris at FL 370 with a routing of MIILS, COLOR, and latitude 47°N longitude
50°W (Oceanic Track "W"). ACA870 was re-cleared from MIILS direct to latitude 45°N longitude
50°W (Oceanic Track "Y"). The new routing placed ACA870 on a converging track with AFR033.
The two aircraft were being controlled by the Gander Area Control Centre (ACC) high domestic
controllers responsible for the combined sector BANCS and south, the two south-easternmost
sectors of the Gander domestic airspace, in which the coast-out points BANCS and RAFIN are
located (see Appendix A, Figure 1). ACA870, with 265 passengers and a crew of 14, had been
issued an amended oceanic clearance by clearance delivery prior to handoff to the BANCS radar
controller. ACA870 contacted the radar controller at 0151:152, outside the geographic boundaries
of the BANCS sector, and crossed the sector boundary at 0207. Position estimate information was
provided by ACA870 to the radar controller indicating that the aircraft was level at FL 370 and
estimating latitude 45°N longitude 50°W at 0227.
AFR033, with 235 passengers and a crew of 14, had received an oceanic clearance and had been
handed off to the radar controller at 0158:32. AFR033, established on the route WHALE direct to
BANCS, was level at FL 370, and estimating BANCS at 0217. The aircraft track during this
portion of the flight was approximately 076° magnetic.
At approximately 0211, as ACA870 approached 40 nm west of the BANCS intersection en route
to latitude 45°N longitude 50°W, the radar controller contacted ACA870 and advised that radar
service would terminate at longitude 50°W and to contact Gander radio on frequency
