The Airbus Helicopters (formerly Eurocopter, formerly Aerospatiale) AS350 Squirrel is a light utility helicopter. It was the first Aérospatiale helicopter which was produced on an assembly line. Moreover, with this helicopter the so-called “Starflex” rotor-head was introduced, a system in which the number of moving parts is only a quarter of the usual construction, reducing the service intervals and decreasing production costs significantly. The first prototype took flight 27 June 1974. The Squirrel helicopter family is still being produced and has world-wide customers.
