MD 520

• Advanced design • No tail rotor • Increased safety

With its sleek shape and peppy performance, the McDonnell Douglas MD 520N is excellent for civil, commercial and police duties. The MD 520N combines a helicopter design from the 1960s (originally built for the military) with an evolving aerodynamic concept (the manufacturer’s NOTAR, or ‘no tail rotor’ configuration) to produce the MD 520N, the helicopter everybody wants. As of 1996, McDonnell Douglas had sold 80 of the type.
