Nextant Aerospace has a new approach to general aviation: The company has been producing the world's only FAA-certified remanufactured business jet, the 400XT. Nextant is working toward outputting 40 aircraft per year, to fill more than 80 existing orders. The idea was developed by aviation entrepreneur Kenneth Ricci, who says complete redesigns are not necessary. "[T]he only thing that's really changing are the engines and avionics ... the computerization. There are no leaps in aluminum landing gear" or other major aircraft components.
