1.4.1 Original Certification of the AS 350 Series

The basis of certification for the AS 350 series is United States Federal Aviation Regulations (FARs) Part 27 (FAR 27), Normal Category, effective 01 February 1965, including amendments 27-1 through 27-10.


The AS 350 series was introduced in 1974 by the Société Nationale Industrielle Aérospatiale (SNIA) of Marignane, France, which later was renamed Eurocopter France (ECF). The model first appeared in two forms - the AS 350 C for North American operations, and the AS 350 B for the European and other markets. The principle difference between the models was that the Avco Lycoming LTS 101 engine replaced the Turbomeca Arriel power plant installed in the AS 350 B model. In due course, several other AS 350 model variants were developed as a result of market demand and technological improvement.


Because France is the country of design, the French civil aviation authority-the Direction Générale de l'Aviation Civile (DGAC) - issued the original product type certificate (H9EU) for the AS 350 B in October 1977. In December 1977, the United States Federal Aviation Administration (FAA) certificated the AS 350 C. Production deliveries of the AS 350 model began in March 1978.





In June 1978, TC issued Canadian type certificate H-83 to the AS 350 C model as the first of the AS 350 series certificated in Canada. In February 1980, the AS 350 B was added to the data sheet of the type certificate, and in July 1988, TC certificated the AS 350 B1. In December 1990, following its technical review, TC certificated the AS 350 B2. The TC certification files for this model contained no record of specific concerns regarding the hydraulic flight control system. In August 1997, the DGAC withdrew the certification of the original AS 350 C, and as a result, TC withdrew the Canadian type certificate at the same time; accordingly, the AS 350 C is no longer certificated in Canada. The following table summarises the Canadian certification history of the AS 350.
