Écureuil

The AS350 Écureuil, known internationally as the AStar, is a single‑engine light utility helicopter developed by Aérospatiale in the early 1970s. Its first flight took place on 28 June 1974, and the type entered service a year later, quickly gaining a reputation for reliability and versatility. After the 1992 merger that created Eurocopter—now Airbus Helicopters—the Écureuil continued production under successive designations (AS350 B, B2, B3, and the latest B3e). Key features include a Turbomeca (now Safran) Arriel turboshaft engine, a fully composite main rotor system, and a spacious cabin that can accommodate up to six passengers or a variety of external loads. The B3e version introduced a full‑FADEC engine control, glass cockpit, and optional EC155‑type avionics, enhancing performance at high altitude and hot‑and‑high conditions. Over 6,000 units have been delivered worldwide, serving roles from aerial work and law‑enforcement to medical evacuation and tourism. Its adaptability and cost‑effective operating profile have made the Écureuil a benchmark in the light‑helicopter market, influencing the design of many subsequent rotorcraft and cementing its place in modern aviation history. It remains in production today, with continuous upgrades that keep it competitive in emerging markets.
