One of the world's most successful and useful light turbine helicopters, the Hughes/McDonnell Douglas/MD Helicopters 500 series began life in response to a US Army requirement for a light observation helicopter.
Hughes won the US Army observation helicopter contest against competition from Bell and Hiller with its Allison 250 powered YOH-6A Cayuse, which first flew in February 1963. By then Hughes was already working on a civil variant, to be marketed as the Hughes 500. However, the engineering and certification designation for all military and civil variants of this helicopter type is Hughes Model 369. It was offered in basic five and seven seat configurations, and a 500U utility version. The 500 and 500U were powered by an Allison 250-C18A engine.
