What happened
After completing its landing, the airplane was taxiing toward the ramp. The incident occurred in a location that was not visible from the air traffic control tower. During the taxi, the pilot looked to the left to prepare for a turn; however, upon looking back to the right, the pilot observed a snowplow truck backing up into the aircraft's right wing.
The operator of the snowplow reported that the aircraft was not visible in his sideview mirror while he was reversing. Following the initial impact, the truck operator stopped the vehicle. As the truck began moving forward again, the airplane struck the truck a second time. The force of the collision pushed the aircraft sideways by 6 inches and caused it to rotate approximately 90 degrees to the right.
