English: This three-dimensional (3-D) animated reconstruction shows the last 2 minutes of the February 12, 2009, accident involving a Bombardier DHC-8-400, N200WQ, operated by Colgan Air, Inc., which crashed about 5 nautical miles northeast of Buffalo-Niagara International Airport, Buffalo, New York, while on an instrument landing system approach to runway 23. During the approach, a pitchup motion occurred, followed by a left roll and then a right roll. During these maneuvers, both the stick shaker and stick pusher were activated, and the speed decreased. After further pitch and roll excursions, the airplane entered a steep descent from which it did not recover. The animation shows excerpts from the flight data recorder (FDR), the cockpit voice recorder (CVR) transcript, recorded radar data, and aircraft performance data. It does not depict the weather or visibility conditions at the time of the accident. The animation does not include audio.
