NTSB Links Fatal Bangor Jet Crash to Deicing Holdover Violation

The National Transportation Safety Board released a preliminary report March 6 regarding the fatal crash of a Bombardier Challenger 650 at Bangor International Airport. All six people aboard died in the Jan. 25, 2026, incident, which the NTSB attributed to deicing holdover time violations during active snowfall.

Critical Timing Violation

Flight data shows the aircraft received Type IV deicing fluid approximately 17 minutes before takeoff — nearly double the nine-minute maximum holdover time for moderate snowfall at minus-16 degrees Celsius under FAA guidelines. Cockpit voice recorder data revealed pilots discussed a "14- to 18-minute standard" without performing required pre-takeoff contamination checks.

Fatal Sequence of Events

The jet accelerated through 127 knots at decision speed but experienced stick shaker activation as ice contamination reduced lift capability. Both engines maintained takeoff power until impact, ruling out mechanical failure as a cause. Emergency crews battled a post-crash fire before the airport closed for four days. The investigation continues as the NTSB examines all factors contributing to the accident.
