The MH2000 is a light utility helicopter manufactured by Mitsubishi Heavy Industries of Japan. It has the distinction of being the first entirely indigenous Japanese helicopter as Mitsubishi had sole responsibility for its development and manufacture. The MH2000 was intended to fill various roles. These included passenger transport, law enforcement, search and rescue as well as medical services. The key values espoused by the designers of the MH2000 were safety, economy and low noise. Development began in 1995 with the first prototype taking flight in mid-1996. The first production model was delivered in 2000. Production of the MH2000 ceased in 2004 due to low demand. The MH2000 has a single, four-blade main rotor and a Fenestron tail rotor assembly. In keeping with the low-noise design of the helicopter, noisy components such as the main gearbox are located aft of the passenger compartment. Making for a relatively quiet ride with minimal vibration. Both the main and tail rotors are made with modern composite materials and the main rotor has tapered tips. The MH2000 can seat seven or twelve, depending on its configuration. Two Mitsubishi MG5-110 turboshaft engines power the MH2000, providing 653 kilowatts each. Interestingly the MH2000 has both a high-speed and low-noise mode which can be selected digitally at the flip of a switch. This gives the helicopter a greater measure of versatility for urban low-noise scenarios or situations where speed is a priority. Despite this, the MH2000 has developed a reputation for being underpowered and main rotor vibration problems. The MH2000 was issued a suspension of its certification following the loss of a prototype. The prototype experienced a tail rotor separation, prompting a redesign of the entire tail rotor. MH2000s that had already been delivered were recalled in order to be fitted with the new rotor design. These and other factors most likely led to the cessation of sales by Mitsubishi in 2004 following lax demand. By 2003 only five production aircraft were registered and only two aircraft were actually earning any revenue.
