EUROCOPTER AS350 B3

The Eurocopter AS350 , originally designed and manufactured in France by AErospatiale (now Airbus Helicopters). In North America, the AS350 is marketed as the AStar. The AS355 Ecureuil 2 is a twin-engine variant, marketed in North America as the TwinStar. The Eurocopter EC130 is a derivative of the AS350 airframe and is considered by the manufacturer to be part of the Ecureuil single-engine family.

The AS350 is a single engine helicopter, powered either by a Lycoming LTS101 or Turbomeca Arriel power plant (for twin-engined variants) that drives a three-blade main rotor which is furnished with a Starflex rotor head. The type is well known for its high-altitude performance and has seen frequently used by operators in such environment. Both the main and tail rotors make use of composite material and are deliberately designed to minimize corrosion and maintenance requirements. The AS350 was also developed to comply with the stringent noise requirements in locations such as national parks . The in-cabin noise levels are such that passengers may also readily converse during flight. The aircraft can also be quickly started up and shut down which is often useful during emergency medical services . It is equipped with hydraulically-assisted flight controls; these controls remain operational albeit operated with greater physical difficulty in the event of a hydraulic failure.
