History

Designed in the early 1970s to replace the Alouette II and III, the Écureuil introduced the innovative Starflex composite rotor head that eliminated traditional bearings and reduced maintenance. It entered service in 1978 and has sold over 5,000 examples. In North America it is marketed as the AStar.

Variants

Major variants include the AS350B, B2, B3 (high-altitude), and the twin-engine AS355 Écureuil 2; military versions include the H125 (AS350B3e) used by several air forces.

Where you'll see it

Operated by police forces, air ambulance services, mountain rescue units, and military training schools worldwide; the H125 variant has been used for high-altitude records including landing on Everest.
