Aircraft Details

The aircraft was originally designed as the Mitsubishi MU-300 Diamond, an all-new, all-jet development to complement and slot above the Mitsubishi MU-2 and provide Mitsubishi Heavy Industries with their top-of-the-line corporate aircraft model (hence the name Diamond). Beechcraft bought the production rights and began manufacturing it as their own model, initially redesigned as the Beechjet 400. The Beechjet 400 was certified by the FAA in May 1985.
