Deice Fluid Ingestion/Smoke
We recently had an incident where the aircraft (B1900D), blew bunches of smoke throught the environmental system during takeoff (bleeds open) at high speed 90-ish knots. This was on a very cold (-22C) night, and after a thorough deicing. The smoke was presumably glycol that went through an engine or two and then through the air cycle machine. Anybody else had this happen? It scared the heck out of the crew and caused an abort.
I just cannot figure out how there could be no issue, no odor, no smoke, while taxiing with the bleeds open, but then smoke up the entire cabin in a matter of seconds once takeoff power was applied. Where was the glycol lurking before takeoff? I'm still trying ot come to terms with this. Any reflections on issues of this nature are welcome, even if your aircraft type is quite different.
