Incident at Calgary, AB (ATS operating irregularity)

Summary

1999-09-15: The crew of ABL 835, a DHC-8, was cleared for takeoff on Runway 16 at Calgary International Airport and instructed to turn right to heading 190 degrees and to maintain 6,000 feet. TSC 945, an L1011, was released on Runway 16 approximately 1 minute after ABL 835 and was advised that ABL 835 would be turning. Before TSC 945 started its takeoff roll, ABL 835 was again given a turn to heading 190 degrees, maintain 6,000 feet and contact Departure in the turn. As TSC 945 lifted off, the Tower Coordinator observed ABL 835 about 2 miles south of the airport, and apparently still on runway heading. The Tower Coordinator told both the Tower Controller and Terminal / Departure Controller that ABL 835 appeared to be on runway heading. The Tower Controller attempted to turn ABL 835 again. There was no response from ABL 835. At this time, ABL 835 was talking to the Calgary Terminal / Departure Controller, who immediately gave ABL 835 a heading of 250 degrees to move ABL 835 out of the departure path. The ABL 835 pilot said that they were never given the turn. Tower audio tapes indicate that ABL 835 was given the turn to heading 190 degrees, however the pilot did not acknowledge the clearance. OPI - ANS and Airspace UPDATE ANS reported that NavCanada will convene a Fact-Finding Board.
