Incident at WINNIPEG / JAMES ARMSTRONG RICHARDSON INTL MB (CYWG) (Conflict - loss of separation, ATS operating irregularity)
2003-05-07: TGO 988, a Beech King Air 90, was working IFR about 20 NM northwest of Winnipeg while C-FEMA, a Cessna Citation departed Winnipeg for Edmonton. Separation between the two a/c was reduced to 2.5 miles before correcting vectors were issued and the 3 mile standard was re-established. The Departure Controller reportedly misjudged the radar separation due to having recently changed the radar ranges.
2003-05-08: UPDATE TSB reported that an ATC operating irregularity and loss of separation occurred 20 NM northwest of Winnipeg, involving TGO 988, a Transport Canada Beech 90, and C-FEMA, a Government of Manitoba Cessna 550. Transport 988 was doing airwork in the northwest practise area at 6,000 feet. C-FEMA was en route from Winnipeg to Edmonton and was vectored through TGO 988's altitude with 2.25 NM lateral separation, in an area where 3 NM is required. The aircraft were under radar control and there was no risk of collision. ANS and Airspace reported that NAV CANADA will hold an Operational Safety Investigation concerning this occurrence.
