Sequence of events

The events NTSB coded, in order, by phase of flight. The defining event is the one that best describes the accident. Under each, the cases with the same event anywhere in their sequence.

Analysis

The airplane was taxiing to the parking area when the right wing tip struck a light pole. The taxiway markings on the ramp were obscured by snow, and the airplane was being guided by ground handlers, including a wing-walker positioned at the right wing tip. The taxi speed was low due to the snow cover and positive contact with the ground handlers was maintained by the flight crew. The flight crew did not feel the impact with the light pole and were not aware of the accident until notified by company maintenance personnel after parking.
