The preliminary report says the small plane was too heavy for conditions that cause icing at the speed and altitude it was flying.

A Cessna plane that crashed while flying to Nome, Alaska, last month, killing all 10 people on board, was hundreds of pounds too heavy for icing conditions, a National Transportation Safety Board report says.

The regional airline flight in Alaska that crashed, killing all 10 people onboard, was overweight before it took off, according to a preliminary report released Wednesday by the National Transportation Safety Board.
