- Date: December 13, 2017
- Aircraft: ATR42-300
- Location: Fond-du-Lac, Saskatchewan, Canada
- Fatalities: 1
- Phase of flight: Takeoff and climb
- Cause: TSB (A17C0146): The aircraft took off with ice contamination that increased drag by 58 percent and reduced lift by 25 percent. Asymmetric lift from uneven ice caused an uncommanded left roll, the roll oscillation grew and roll control was lost, and the aircraft collided with terrain.
On 13 December 2017 a West Wind Aviation ATR 42 320 took off from Fond du Lac Airport with 3 crew and 22 passengers, carrying residual ice and frost from the earlier landing and a ground stop at the remote airport. Immediately after liftoff the aircraft rolled left, the roll developed into an oscillation, roll control was lost and it hit terrain 17 seconds after takeoff. The TSB (A17C0146) found the crew continued a departure with contamination, the airframe lacked crashworthy design features and the collapsed wing structure caused serious injuries; one seriously injured passenger later died.
