Incident at YELLOWKNIFE NT (CYZF) (Conflict - potential, ATS operating irregularity)


2003-07-14: UPDATE ANS and Airspace reported that Nav Canada completed a Level 2 Operational Safety Investigation.
2003-03-24: UPDATE TSB reported that the Summit Air Charters Shorts Skyvan SC-7, C-GJGS, was cleared to land when on a five mile final approach for Runway 27 at Yellowknife. A taxiing Air Tindi BE20, Flight AT 502, registered C-FCGU, was cleared to position on Runway 27 at the same time to await takeoff clearance. The crew of AT 502 and C-GJGS, as well as the Tower Controller, noticed the potential conflict and took corrective action independently. AT 502 proceeded no further than the runway edge, and the Tower Controller instructed C-GJGS to conduct a missed approach which had already been initiated by the Skyvan crew when it was two miles from the runway. AT 502 subsequently departed and C-GJGS landed without further incident. The weather was clear with unlimited visibility at the time of the occurrence.
2003-03-17: C-GJGS, a Shorts SC7, was inbound VFR to Yellowknife from Hilltop Camp and the crew reported 5 mile final to land on Runway 27. They were cleared to land by the Tower Controller. AT 502, a Beech King Air, was cleared to position on Runway 27 and the Controller believed that there was sufficient time for AT 502 to depart. C-GJGS then reported 2 mile final and the crew did a 360 degree turn for spacing because AT 502 was still on the runway. AT 502 then departed from Runway 27 and C-GJGS landed on Runway 27 without incident. An Operational Safety Investigation has been recommended.
