If ya' can't pressurize a PA32, that ain't gonna happen either.Piper tried to pressurize the Aztec, and that did not work.They did pressurize the Navajo (also known as the Mojave), but that plane is only for those who love to waste money.A turbocharged engine does not, of course, mean the plane has a pressurized cabin. If it were pressurized it would look as bad, if not worse then the new Mooney Acclaim, which can hardly carry anything with all options and full fuel!Piper Seminole? It's just a PA28 airframe with two engines. Heck, the latest Saratoga II TC has a useful load that makes it look more like a Cessna 172 as to load carrying ability. Yes, no doubt that some 'look' like they are pressurized, such as some Mooneys and the Piper Saratoga, but.As to the Saratoga II TC, only a visit to the Piper web site will tell you if it is pressurized or not (the plane is still built today), and with any knowledge of the PA32 line it should go without saying these these are not, nor will they ever be pressurized aircraft. Interesting thread as to the answers when it comes to pressurized piston singles.
