An MD 530N helicopter took to the air for the first time on December 29, 1989. This McDonnell Douglas offering, which features the NOTAR anti-torque system, is reputed to be the first conventional, single main-rotor helicopter minus a tail rotor for anti-torque directional control. NOTAR-equipped helicopters, which will be available on both MD 530N and MD 520N configurations, are the latest versions of the MD 500, which first flew in 1963.
