Narrative:
The pilot's of Air Canada flight 106 were warned of other traffic 1 mile in front of them, but they were unable to see it. A little later a slight jar was felt. The Viscount had collided with an Ercoupe 415 (CF-SHN), which spiraled down after the collision.

PROBABLE CAUSE: "The see-and-be-seen concept, although augmented by radar, was ineffective. The procedures to ensure safe separation of mixed traffic in the Vancouver area are obsolescent."
