MITSUBISHI DIAMOND I/II/III

The Diamond I was introduced in 1979 as Mitsubishi's example of a 500-mph-plus executive fanjet. Its twin turbofans are rated at 2,500 lbs. s.t. for takeoff and 2,375 lbs. s.t. for maximum continuous operation. The two Diamond I prototypes underwent 350 hours of test flying in Japan before their arrival in the United States for FAA certification. A Diamond offers the performance characteristics, cabin size, and comfort level of the medium-class swept-wing jets plus the low cost and economy associated with light jets and some turboprops. The Diamond I wing design, with its advanced flight control system of full-span flaps, wing spoilers, and T-tail empennage, is built for optimum performance. (For more, see HAWKER 400XP).
