Is it Cessna 406?

I think they said in a few episodes that it was a Cessna 402 or something. I don't know anything about airplanes http://www.sitcomsonline.com/ubb/wink.gif

It was a Cessna 401 and a 402. They used more than one. They are almost exactly the same. The planes they used belong to a Company called Cape Air. If you ever go to Boston or Providence Airport you will see these planes.

I think there are two tipes of planes in the show
The one that is always in the hangar is a Cessna 421; but the plane that's always in the field is a Cessna 414. The structure is different but is very hard to say If I'm right. I read somewhere around here that too (Cessna 414/421).-
