Eurocopter AS355 Ecureuil 2 / Twin Squirrel Helicopters for Sale
The Eurocopter AS355 Ecureuil 2 — known as the Twin Squirrel in English-speaking markets — represents the logical twin-engine evolution of the renowned AS350 Ecureuil family. By installing two Allison 250-C20F turboshaft engines in the proven AS350 airframe, Aerospatiale (later Eurocopter, now Airbus Helicopters) created a helicopter that delivers the Ecureuil's famous agility and cabin space with the operational safety margins of twin-engine redundancy. The AS355 has served police aviation units, news gathering organizations, offshore operators, EMS providers, and corporate flight departments across five continents — proving that the twin-engine formula works as well in a light helicopter as it does in larger categories.
AS355 Variants
- AS355E — Original twin-engine Ecureuil with Allison 250-C20F engines. Established the platform with proven twin-engine safety margins in a compact airframe.
- AS355F / F1 / F2 — Progressive improvements to engine rating, transmission, and systems, with the F2 being the definitive Allison-powered variant.
- AS355N — Significant upgrade featuring twin Turbomeca TM319 Arrius 1A engines replacing the Allison units. Improved fuel efficiency, smoother running, and better hot-and-high performance characterize the N variant.
- AS355NP — Final production variant with Arrius 1A1 engines, further refined performance, and modern avionics compatibility.
The Twin Safety Margin in a Light Airframe
The AS355's compelling value proposition is delivering twin-engine safety margins in an aircraft that costs significantly less to acquire and operate than the larger medium twins like the AW109 or EC135. For operators flying over water, over urban areas, or in conditions where a single-engine failure would be catastrophic, the AS355 provides the redundancy that regulations or risk assessments demand without the full cost burden of a medium twin. Police aviation units particularly value this combination — twin-engine safety for crews operating at low altitudes over urban environments, in a compact platform that can navigate urban airspace effectively.
