25 April 1985: Flying a McDonnell Douglas Helicopter Company MD530F, Allison Chief Test Pilot Frederick Jack Schweibold sets a Fédération Aéronautique Internationale (FAI) world record for speed over a recognized course from Kansas City, Missouri, to Indianapolis, Indiana, at an average speed of 276,12 kilometers per hour (171.573 miles per hour).¹

The MD530F (Model 369FF) is the most powerful variant of the Model 369 series, which was originally produced by Hughes Helicopters as the military OH-6A Cayuse Light Observation Helicopter. It is optimized for “hot and high” operations. It has longer main rotor blades than the MD500E, and is powered by an Allison 250-C30 turboshaft engine. The helicopter is now produced by MD Helicopters, Mesa, Arizona.
