Hughes announced it was developing a civil version, to be marketed as the Hughes 500, available in basic five and seven seat configurations. The improved Hughes 500D became the primary model in 1976, with a more powerful engine, a T-tail, and new five-blade main rotor; a four-blade tail rotor was optional. The 500D was replaced by the 500E from 1982 with a pointed nose and various interior improvements such as greater head and leg room. The 530F was a more powerful version of the 500E optimized for hot and high work.
McDonnell Douglas acquired Hughes Helicopters in January 1984, and from August 1985 the 500E and 530F were built as the MD 500E and MD 530F Lifter. Following the 1997 Boeing/McDonnell Douglas merger, Boeing sold the former MD civil helicopter lines to MD Helicopters in early 1999.
The MD 520N introduced a revolutionary advance in helicopter design being dispensed with a conventional anti-torque tail rotor in favor of the Hughes/McDonnell Douglas developed NOTAR system. Exhaust from a fan is directed through slots in the tail boom, using the Coanda Effect to counteract the torque of the main rotor, and a controllable thruster at the end of the tail boom is used for yaw control.
McDonnell Douglas originally intended to develop the standard MD 520 alongside the more powerful hot and high optimized MD 530N (both were launched in January 1989 and were based on the conventional MD 500E). The MD 530N was the first to fly, on December 29, 1989, the MD 520N first flew on May 1, 1990. Development of the MD 530N was suspended when McDonnell Douglas decided that the MD 520N met most customer requirements for the 530N. Certification for the MD 520N was awarded on September 13, 1991, and the first was delivered on December 31 that year.
In 2000, MD Helicopters announced enhancements to the MD 520N including an improved RR 250-C20R+ engine with 3-5% more power for better performance on warm days, and, with changes to the diffuser and fan rigging, increased range.
