Incident at Regina, SK (Conflict - near collision (VFR or IFR))


1997-08-20: C-GTOQ, a Cessna 172, was doing touch and goes on Runway 31 at 0400Z as the Tower was closing for the day. Traffic was then turned over to the FSS for advisory service. Winnipeg ACC advised FSS of two arrivals: ACA 153, an A320 from Toronto due at 0410Z, and CDR 1330, an F-28 from Calgary due at 0415Z. FSS passed on the arriving traffic to the pilot of C-GTOQ. ACA 153 landed on Runway 31at 0416Z without incident. CDR 1330 reported established on the ILS for Runway 13 at 0419Z just as C-GTOQ was on short final for Runway 31. CDR 1330 was given the airport advisory, and the traffic was reported to the pilot of C-GTOQ who elected to make a left turn immediately after takeoff. At the same time, the crew of CDR 1330 broke off the approach on short final and made a right turn. The two a/c flew on a converging path and were advised of this by FSS. The pilot of C-GTOQ then turned back to the right to avoid CDR 1330 and passed below the F-28. Winnipeg Centre then issued another clearance for CDR 1330, which completed the approach for Runway 31 at 0422Z. UPDATE When the Regina Terminal Control position is not manned and the Tower is closed, a five mile radius Mandatory Frequency area exists, and traffic is turned over to the Regina FSS directly by the Winnipeg ACC enroute controller. The written agreement between the FSS and ACC specifies that the enroute controller will advise the FSS of the position of the inbound IFR a/c, request traffic information within the MF area, and will relay this traffic information to the IFR a/c before entering the MF. The enroute controller will also ensure that the a/c report to FSS not later than 10 miles on a straight-in approach. In this incident, it appears that the information was not relayed to the F-28 crew. The F-28 was not turned over to FSS until inside 8 miles and did not have the traffic information. Part of the delay was incurred while the enroute controller was waiting for a down time for the A320 before turning over the F-28 to the FSS.
