July 30, 1997

Incident at near Waterloo VOR (ATS operating irregularity)

ACA794 (C-GAVC) BOEING 767 AIR CANADA ACA162 was inbound to Toronto (LBPIA) via ECK direct descending to 7,000 feet. ACA794 was also descending to 7,000 feet and was direct to Toronto (LBPIA), approximately 10 NM behind and south of ACA162. As ACA162 appraoched the TCU boundary, the TCU coordinator told the Kitchener controller to give both ACA162 and ACA794 a delaying 360 degree turn due to traffic in the TCU area. ACA794 was re-cleared to 10,000 feet and ACA162 re-cleared to 8,000 feet. ACA162 was issued a 360 degree turn to the right and came within one and one-quarter of a nautical mile and 600 feet of ACA794 as ACA162 was only out of 9,400 feet in the turn. NAV CANADA indicates that (their) investigation continues. Supplemental information from T.S.B. Initial Notification (#A97O0147): ACA162, an Airbus A-320, was inbound to Toronto descending to 7,000. ACA794, a Boeing 767, was also inbound to Toronto and descending to 7,000 feet about 10 miles behind and a little south of ACA162. Becasue of traffic congestion in the Toronto TCU, the TCU co-ordinator requested the Kitchener controller delay both aircraft by giving them a 360 degree turn. ACA162 was re-cleared to 8,000 feet and ACA794 was cleared to 10,000 feet. Both aircraft were approximately 10,000 feet when ACA162 was issued a 360 degree right turn. The right turn took ACA162 across the flight path of ACA794. The aircraft rate of descent was less during the turn and when the two aircraft were abeam, going in opposite directions, the spacing was reduced to 1.25 NM and 600 feet in an area where five (5) miles or 1,000 feet is required. NAV CANADA is investigating.
