Incident 8ml N of Victoria Int ernational Airport 31-Mar-2000 A Cessna 172, registration N8522U, serial number 17252422, was en route from Arlington, Washington, to Nanaimo, British Columbia. The aircraft was flying under visual flight rules (VFR) at 4500 feet above sea level on a north westerly heading. On initial contact, the Victoria, British Columbia, terminal airspace (YYJ) terminal controller assigned a transponder code, radar identified the flight, and approved the flight to proceed as requested to Nanaimo. About one minute later, a West Coast Air de Havilland DHC-6 (Twin Otter), call sign C606, serial number 94, checked in with the YYJ terminal controller. The Twin Otter was radar identified and approved to proceed to Victoria Harbour at 4,500 feet above sea level on a south-southwesterly heading.

Another controller reported for duty at this time. The first transmission received by the new controller when he took over the Victoria VFR traffic advisory frequency was an advisory from the Cessna pilot stating that he was descending because of a Twin Otter. At about 10:18 Pacific daylight time, the Cessna and the Twin Otter came into proximity of each other, necessitating evasive action by the Cessna pilot. The Twin Otter pilot did not see the Cessna in time to take evasive action.
