PCL crew diverts to GRR -carbon monoxide

[SpiraMirabilis]

Janitrol foot bomb! I once did a flight in an ATP Seminole where it was inop in winter. ONLY ONCE. Ice was forming on me. It's hard to practice an ILS when every part of you is shivering.

I flew CPS-MEM once in a baron (in January) with what proved to be an inop Janitrol. Once. I was shivering so much it was hard to manipulate the controls.

Our 99s have carbon monoxide detectors and are obviously not lowly recips. But then again, they have Janitrols, although luckily most also have bleed heat.

I've been noodling on where the CO could have come from too. The flight deck has its own dedicated plumbing and everything gets vented out through the cargo compartment, so it is unlikely anything from the passenger compartment or cargo area would flow up front.

If something were burning and producing enough CO to affect the pilots, I would have expected accompanying smoke or odor (which may not have been reported).

The best guess I can think of now is that a significant amount of engine or APU exhaust was being ingested by a compressor section while the aircraft was on the ground (or the ground air supply gassed them) ... or they flew through a really big, rogue cloud of carbon monoxide during departure.

Or, the trace amount of CO detected after landing is a red herring.

I don't know why, but that just cracks me up. Guess it's a visual thing...oh wait...you can't see it! Holy crap!!! I'm scared now...how can I avoid these rogue clouds?!?

Will have to check back later and see if they find anything.
