About the 355F1

The Aerospatiale 355F1 is a French twin-engine rotorcraft designed for roles such as law enforcement, emergency medical services, passenger transport, and search and rescue. It suits operators requiring a versatile multi-role helicopter and features a spacious cabin layout accommodating up to six passengers alongside a pilot and co-pilot, powered by twin turboshaft engines driving a main rotor via a common gearbox.

Background development of this twin-engine variant stemmed from the earlier single-engine series, incorporating a distinctive Starflex main rotor hub built with a glass cloth and epoxy resin central component to reduce part count and weight. Over the course of production, the airframe saw upgrades including wider chord rotor blades and increased maximum takeoff weight capabilities under various designations before manufacturing concluded.
