Incident at Calgary, AB

Summary

1999-03-18: C-GVCA, a Lear 35, departed Calgary for an IFR flight to Thunder Bay and the Controller issued an altitude restriction of 9,000 feet ASL after takeoff to avoid conflict with an inbound a/c which had been cleared to descend to 10,000 feet ASL. As the two a/c approached each other, the Controller observed that C-GVCA appeared to be climbing, leaving 9,400 feet. When questioned, the crew replied that they were at 9,000 feet, although the Controller observed 9,500 feet on radar. Shortly after, the radar target descended to 9,000 feet. In a preliminary investigation, NavCanada determined that the crew had been cleared to 9,000 feet and the clearance had been acknowledged. OPI - Enforcement
