Incident at Vicinity of Brandon, MB (Conflict - potential, ATS operating irregularity)


1999-03-23: WJA 85, a B737, departed Brandon for Calgary and the crew requested FL 260, but were cleared only to FL 200 because of opposite-direction traffic, ABL 838, a DHC-8 at FL 210 enroute to Winnipeg. The clearance was issued through Brandon FSS and on initial contact with Winnipeg ACC, the crew of WJA 85 indicated that they were climbing to FL 220. When questioned about the altitude restriction of FL 200, the crew of WJA 85 insisted that they were cleared to FL 220. The site manager in Brandon was contacted to look into the occurrence and the tapes revealed that the clearance restriction of FL 200 was issued correctly by the FSS specialist, but the incorrect readback from the crew of WJA 85 was not caught by the specialist. The internal NavCanada investigation is continuing. OPI - ANS and Airspace; Enforcement UPDATE ANS and Airspace reported that NavCanada is conducting a Fact Finding Board concerning this occurrence.
