Hey Velojym, that's the same cockpit as the 1900... now imagine when someone spills coffee or another drink.
Our pilots didn't leave anything sticky (thank goodness) and there were no odd stains under the upholstery.
The passenger cabin, however, was an entirely different story. Try scrubbin' old dry soda from the hull under floor level.
It's enough to drive you nutz!
Lots of wiring and ductwork, and I wished my arms were an inch thick with 6 or 7 joints. I had to do a lot of it with forceps.
Ok, I don't want to think about it anymore. Suffice it to say, our charter planes sometimes came back with... interesting messes
in 'em. (The grandson of the FBO owner had a little party in a base customer's Falcon, doing about $50,000 worth of damage, including
cleanup, in the cabin... I might pay that for a whole airplane!)
