MONTREAL (AP) _ A small commuter plane that was rerouted because of smoke in the cabin crashed while landing today at Mirabel airport, killing all 12 people aboard, police said.

The plane was based at nearby Dorval airport and was headed to Ontario, according to the Royal Canadian Mounted Police.

``We were told there was a technical problem,'' said Sgt. Marcel Parent.

After the pilot reported smoke in the cabin, the control tower directed the plane to land at Mirabel, he said.

The weather did not appear to be a factor, Parent said. It was cloudy, but not raining this morning at the airport, 25 miles northwest of Montreal.

Two hours after the crash, smoke could still be seen billowing from the aircraft at the end of one of Mirabel's runways, and emergency vehicles surrounded the wreck.

The King Air twin-engine commuter plane, owned by the Quebec-based Prop Air, was carrying two crewmembers and 10 passengers, police said.
