A preliminary NTSB report into the Jan. 25 Bangor Challenger 650 takeoff crash shows the jet received de-icing and anti-icing but then sat 17 minutes after treatment—exceeding FAA’s 9‑minute holdover guidance and roughly eight minutes longer than recommended—before a night departure in snow.

Briefing
NTSB preliminary data shows a 17‑minute post-treatment hold versus FAA guidance of 9 minutes (about eight minutes longer than recommended), a concrete timing metric that directly affects contamination risk and go/no‑go decisions in icing conditions. See prior coverage of the Bangor crash for context (Bangor crash cluster).
The finding intensifies scrutiny of de‑icing operational limits, contamination detection and post‑treatment checks, reinforcing earlier calls to review de‑icing policy and tactile inspection practices (de‑icing limits context; tactile inspection guidance).
