Incident at YORKTON MUNI SK (CYQV) (ATS operating irregularity)

1996-05-09: An operating irregularity existed between MNS100, a Dornier 228 and Westwind WEW1051, a Cessna 401. MNS100 departed Winnipeg IFR at 8000 feet Langruth direct Saskatoon. WEW1051 departed Regina at 1205Z direct Tisdale at 8000 feet. One controller estimates the aircraft only had 5 minutes on a crossing track. This was not noticed until 1225Z when MNS100 progressed abeam Yorkton. At this point MNS100 was 23 miles from the conflict point. The controller took action and had MNS100 climb to 9000 to resolve the possible conflict. MNS100 was 5 minutes late abeam Yorkton so there was actually 11 minutes separation between the aircraft on a crossing track. ATC Shift Manager are investigating the incident.
