Summary

1997-05-27: Canadian Regional 1920 (FK28) was at 3,600 feet, 12 miles inbound (ASHTN intersection) for runway 07. Transport 858 was flying a flight management system approach to runway 07 and turned from downwind to right base, at the same altitude resulting in a loss of separation. Supplemental information from T.S.B. Initial Notification (#A97O0084): CDR1920, a Fokker F28, was conducting a straight-in ILS 07 approach at Ottawa (M-CIA), ON. TGO858, a Cessna 500 Citation, was conducting a flight management system (FMS) River 2 Arrival Procedure or the straight-in ILS 07 approach at Ottawa (M-CIA). The aircraft were operating in visual meteorological conditions (VMC) and the Ottawa Arrival Controller pointed out the Fokker F28 traffic to TGO858. The with traffic in sight, the Arrival Controller cancelled the FMS River 2 Arrival Procedure and cleared TGO858 for the straight-in ILS 07 approach. TGO858 proceeded to turn the base leg to the final approach fix (FAF) with CDR1920 ahead and on the final approach leg. Spacing was reduced to 2.5 nautical miles (NM) lateral and 500 feet vertical in an area where 3NM lateral or 1,000 feet vertical is required. NAV CANADA is not conducting a fact-finding board.
