Wow - Good job Pinnacle Crew and ATC
 

Incident: Pinnacle CRJ2 near Grand Rapids on Dec 16th 2009, carbon monoxide in cockpit, both crew having trouble
Scary Stuff

Scary indeed. They seemed to have handled it very well. Where do you suppose the CO came from?

Great job in trusting your senses when something "just don't feel right"

Management Farted into the Packs

They should've turned off the cabin heat! Their muffler shroud must be damaged and leaking!

Maybe their heater hose to the exhaust manifold had a leak? :)

Watched it happen as we did box vectors waiting for them to land. Ended up taking a lot of the pax to DTW with us.

I have always wondered about CO2 in the cabin. Unless something is burning I'm not sure where it would come from in a jet aircraft. Bleed air from the engines is extracted from the compressor. Simple physics shows that a gas will go from a higher pressure to a low pressure so I'm not sure how the combustion could flow back into the compressor on a high bypass turbofan. In no way am I doubting this situation. Clearly they had some type of contamination. Does anyone have an idea as to where this sort of thing could come from if nothing was actually burning?

There is plenty of CO2 (Carbon Dioxide) in the cabin...since when you exhale that is what you partially blow out.

CO (Carbon Monoxide) however shouldn't be there. How it gets there is beyond me.

Ooopss, yeah my bad on that. Thanks for the correction!;)
