Historical Note
The Aerospatiale AS 350 Écureuil (Squirrel), known as the AStar in North America, represents one of the most successful light utility helicopter designs in aviation history. First flown in 1974, the AS 350 quickly established itself as a versatile workhorse for civilian and governmental operations worldwide.
Throughout its distinguished service life, the AS 350 has proven invaluable in diverse roles including emergency medical services, law enforcement, news gathering, corporate transport, tourism, and utility operations. Its exceptional high-altitude performance made it legendary in mountainous regions, with AS 350s regularly operating in the Himalayas, Alps, and Andes. The helicopter achieved worldwide recognition when an AS 350 B3 landed on the summit of Mount Everest in 2005, setting an altitude record that demonstrated the aircraft's remarkable capabilities.
The B-series variants covered in this manual collection represent the evolution of the design through multiple powerplant and systems improvements. From the original AS 350 B with the Lycoming LTS101 engine to the later Turbomeca Arriel-powered versions (B1, B2, B3), each variant brought enhanced performance and reliability. The BA and BB models introduced specific improvements for different operational requirements, while the D variant featured the Turbomeca Arriel 1D engine. These helicopters saved countless lives in search and rescue operations, supported critical infrastructure projects, and enabled operations in environments where few other aircraft could venture.
Production of AS 350 variants exceeded 6,000 units, with the type serving operators in over 120 countries. The helicopter's reliability, maintainability, and versatility made it a favorite among commercial operators, and many examples continue flying today after decades of service. The AS 350's success led to the development of the twin-engine AS 355 Écureuil 2 and influenced subsequent Eurocopter (now Airbus Helicopters) designs.
These original technical manuals represent the authentic documentation used throughout the AS 350's operational life by pilots, maintenance technicians, and engineers. They provide comprehensive insight into the helicopter's systems, maintenance requirements, and operational procedures as specified by Aerospatiale and later Eurocopter. For historians studying rotorcraft development, restorers working on preserved examples, or enthusiasts seeking to understand this remarkable helicopter's technical details, these manuals offer invaluable primary-source material from the aircraft's active service period.
