February 16, 2017: Fifty years after its first flight on 16 February 1967, the BO105 is still appreciated around the world for its versatility, reliability and quality. During its heyday, the BO105 was the most innovative light helicopter on the market. Most notably, the introduction of its hingeless main rotor head paved the way for the bearingless rotor systems of today’s helicopters. Some 1,400 units were delivered to more than 300 customers around the globe between 1970 and 2009. With approximately 400 aircraft still in service, the BO105 is a living legend.
