Origin of the MD 500 Series
In the 1960s, the US Army launched a competition to develop a Light Observation Helicopter (LOH). Among the competitors was Hughes Tool Company, which won the contract in 1965 with the OH-6. Even before the OH-6 took flight, Hughes announced plans for a civilian version of the aircraft, the MD 500.
Marketed as the Hughes or MD 500, the helicopter became available in five- and seven-seat configurations. The improved Hughes 500D, introduced in 1976, quickly became the primary model, thanks to its upgraded engine, distinctive T-tail, and five-blade main rotor. In 1984, McDonnell Douglas acquired Hughes Helicopters. Following the Boeing-McDonnell Douglas merger in 1997, Boeing sold the MD helicopter lines to MD Helicopters.
Today’s MD 500
The modern MD 500 series includes models like the 500E, 520N, and 530F. These helicopters are commonly used for utility jobs, police work, emergency services, military operations, and helicopter charters. Known for its speed, this helicopter also stands out for its exceptional maneuverability in hot climates and high-altitude environments.
