NTSB releases preliminary report on Challenger 650 crash in Maine

The NTSB released the preliminary report on the Challenger 650 (N10KJ) that crashed near Bangor, Maine on Jan. 25. The jet departed William P. Hobby Airport (HOU) at 2:20 p.m. CST on a two-leg flight to the Châlons Vatry Airport (FOK) in France. It stopped at the Bangor International Airport (BGR) at 6:09 p.m. EST and was taxied to the FBO ramp at 6:15 p.m. The engines were shut down and the aircraft remained powered by the APU while refueling. The aircraft was then taken to the deice pad at 7:19 p.m. EST. After the anti-icing application, the Challenger sat for 4 minutes 51 seconds before it taxied from the deice pad and stopped 200 ft away from the runway hold short line. At the time, the weather conditions were reported to be 16 degrees Celsius with light snow and a surface wind at 6 to 8 knots, according to the report. The aircraft was cleared for takeoff at around 7:42 p.m. and resumed taxi to the runway. It began to take off at around 7:43 p.m. The jet's altitude was 31 ft, though this height value was likely affected by the roll angle.Multiple CCTV cameras caught the aircraft's impact, followed by multiple explosions, according to the report. The pilot, co-pilot and all four passengers were killed. The report states that the Challenger stayed on the ground 8 minutes longer than it should have after receiving deicing treatment in the snowstorm.

The passengers were Houston lawyer Tara Arnold, event planner Shawna Collins, chef Nick Mastrascusa and sommelier Shelby Kuyawa, according to PBS News. Collins, Mastrascusa and Kuyawa all worked for Arnold's luxury travel company, which the Challenger was registered to. The jet should have waited no more than 9 minutes from the start of the deicing treatment before taking off, according to Federal Aviation Administration guidelines. The cockpit voice recorder captured the pilot stating that it was standard to wait 14 to 18 minutes and that they would have to return to the ramp to deice again if the wait was over 30 minutes. The co-pilot agreed with the pilot. "There is no doubt in my mind that the loss of control at liftoff - which was accompanied by an aerodynamic stall warning and sudden right bank - was likely due to snow and ice contamination on the right wing," said aviation safety expert Jeff Guzzetti to ABC News.
